Zoom H4n , I Impressive with minor flaws

Tuesday, December 27, 2011

In looking for a portable handheld recorder for scratch tracks and samples, I weighed the benefits of a few of the handhelds available today and settled on the H4n. The other recorders on my short list were the Edirol R-09 and Sony PCM-D50, and also the H4. So far the H4n hasn't disappointed.

I settled on the Zoom H4n for a couple of reasons:

1) 1/4" and XLR inputs with phantom power - Very handy for throwing a mic on a kick and snare, and the H4n will record those plus the internal condensor simultaneously, which is perfect to get the rest of the drum kit for some quick loop scratch tracks.

2) More geeked out features than the others - They are not needed but still fun to have. The H4n is like the Leatherman of handheld pocket recorders with plenty of built in effects (which sound really good btw), built in 4 track recorder mode, tuners and metronome, playback speed control, MP3 encoder, acts as USB audio interface (both input and output), built in monitor speaker, and more. I also like the little things I'm still discovering, like when I put Ni-MH batteries in and then plugin in the adapter it recharges the batteries.

3) Build - I like the build quality compared to the H4 - Not as nice as the Sony but the thing does feel solid and substantial in your hand. The built in mics are a little exposed without a wire cage on the top like others have, it would probably not be a good thing to drop this unit and have the mics hit first.

4) Cost - This recorder was midrange even with it being brand new. It's less than the Sony and more than the H4 or R-09. I suspect the price will come down a bit when it's been out for a couple months down to where the R-09 is now. For what it has built in it's amazing to be it's as inexpensive as it is.

5) Sound quality - The H4n sounds clean. I believe turning on the built in compressor, or boosting a really weak input signal with a lot of input gain could cause hiss, but for the most part I don't notice any. Usually the noise floor is so low on what I've recorded that it is not audible. Some different mics and setups might have different results, time will tell.

6) Menu and button layout - I really like the way they set this unit up. Very easy to navigate and record with, and does what I want quickly with only a few caveats mentioned below.

7) SD card format - SD cards are cheap and readily available. I don't care so much for the memory sticks the Sony uses.

Now the downsides, maybe all these handheld recorders suffer from similar issues but I'm going to give my first impressions never having used one before and the H4n is the best I have to compare with:

1) Menu system - While easy to navigate, still feels like it could use refining through a firmware update. It feels like it wasn't finished when the product shipped. The fonts look a little like a 5 year old put them together, Zoom could have done better with the screen they put in the H4n. A lot of products like this are rushed to market to meet revenue goals, so hopefully they will get time to take another look at the firmware and make UI improvements. Also the firmware is trying to be a little too fancy with the menus. There is a little expanding box effect that happens when you open a menu, but it ends up just looking like screen artifacts when changing the menus. It would have been better to immediately jump to the menu, it would be faster and would look better.

2) File naming (another UI complaint) - I really wish the firmware gave you the ability to delete a character in a file name. The filename can be edited, but characters can only be added or changed, not deleted. If you use divide alot, the name gets larger and larger but cannot be made smaller. This is a bit annoying when combined with the divide implementation....

3) No divide while recording - there is no divide while recording that I could find. It seems like it would have been very easy to make one of the unused buttons act like a divide when recording. Instead you can set a "mark" (non editabled btw, after one is set it is permament in that wav file). The marks let you easily jump to that point and divide it later, but when it divides the file you end up with an 'A' or a 'B' tacked on to the filename. Now, imagine recording an entire gig or practice with only marks to use to delimit the songs, and then you have to divide them later with the naming scheme and lack of delete character function I mentioned above. What you end up getting is files named something like 'STE-001A.wav', STE-001B.wav', 'STE-001BBBBA.wav', and eventualy 'STE-001BBBBBBBBBBBBBBBBBA.wav' etc and there's not a lot you can do on the device to fix it since the best you can do is replace the extra characters with spaces so that you end up with a file named something like 'song blah .wav' (you can plug it in as a USB interface later and fix all the filenames in the folders, but not a lot you can do on site except stop and restart recordings versus using "marks").

4) Documentation - I'm not sure what Zoom was thinking here. The documentation looks like it was passed through a translation program without any proof reading before shipping. It is filled with sentences such as "On stereo mode can be made 19 different setting using. WAV & MP3. If you want to change, operate before recording". I get the general intent most of the time but it hurts. Luckily the unit is easy enough to use that you don't have to rely on the documentation too much.

As I see it, the complaints I have are mainly around details of the UI implementation and documentation and relatively minor. All around the unit is great and a lot of fun to use. The sound quality is top notch, and the capabilities of the device are astounding. I would have given it 5 stars if the few UI details had been better thought out and someone had read the documenation. For a great all around handheld recorder with excellent sound quality, lots of features, and a reasonable price, the Zoom unit is going to be very hard to beat.

Zoom H4n : Step to Upgrade System Software

Monday, December 26, 2011

In my opinion, now the portable audio with a wide variety and the most cost happens in the market, one the best is Zoom H4n, but when I bought them late last year, it was discovered that there are limitations.

I have created some uneasiness was recorded by a microphone into the input 1 and 2 in the bottom of the machine, it can not split gain (acceleration signal) of each device. Gain-sharing is required, for example, that if someone speaks mic1 lighter mic2 can not use only gain the necessary mic1 up to the mic2 together.

When I purchased the Zoom H4n, the system software (firmware) version 1.5 and later, it is the Zoom out until the latest update to the v1.72 by a significant increase is that we can split gain of input1 and input2 by  separate and independent, and it is grace ... appreciate it.

I was talking about the update system software. Actually it is very easy. Let them see a good step.

1. To download Zoom H4n system software version 1.72 (latest as of now) from this link http://www.zoom.co.jp/downloads/h4n/software/?lang=en.

2. Then extract the zip file and get a file named SYSTEM.BIN.

3. Connecting a Zoom H4n to a computer with a USB device, select the Storage mode (if it not found the USB cable, remove the SD card from your H4n to connect directly to it at all).

4. Throw a SYSTEM.BIN file into the root directory of the SD card of the Zoom H4n ... cast into thinking it is not anywhere to put it into the folder.

5. Disconnect the USB cable of the Zoom H4n to a computer. Or bring the SD card that came with the computer directly to the SD card I put back into the H4n as it was.

6. Turn on the Zoom H4n, press [PLAY / PAUSE] Now hold on.

7. Use the rotate [DIAL] to the side of the H4n to move the cursor down to "OK".

8. Rotate the [DIAL] to begin the update.

This is done to update the system software version 1.72.

Zoom H4N Portable 24-bit Sound Recorder

The H4 remains one of the most flexible of the current crop of portable 24-bit recorders, but Zoom have found plenty of room for improvement — and, more importantly, they’ve used it.

Zoom’s H4 digital stereo recorder remains hugely popular and, despite a few reservations, is one of my favourites. With ‘combi’ jack/XLR inputs, 48V phantom power, a coincident stereo pair of mics onboard, and masses of extra functionality (from four-track mixing to guitar effects and a USB audio interface) it’s much more versatile than most recorders, and the sound is good for the price. The H4’s preamps could be better, navigating the menu can be fiddly, the casing might be a bit more robust, and so on, but on balance it’s an excellent portable recorder.

N-Power
It should come as little surprise, then, that Zoom are continuing to sell the H4, while releasing an improved model that addresses many criticisms made of the earlier model. The H4N comes in at a slightly higher price but, like its sibling, boasts a feature set that makes other recorders look positively lightweight.

The H4N’s body has a thick, rubberised coating, which tackles concerns about handling noise pretty effectively — not to mention making the whole device feel more solid, better weighted, and altogether more ‘professional’. If you do find handling noise an issue, there’s a camera-tripod mounting socket on the rear, and a separate mic-stand adaptor for this. If noise is still a problem, there’s an optional remote control that plugs into the main unit via a mini-jack on the left-hand side panel.

Other striking visual changes include a slightly clearer screen (the one on the H4 was already pretty good) and a new control layout. Gone are the rather fiddly controls of the H4: you now have dedicated transport, input- and track-selection controls on the front panel; and the mystifying two wheel/button menu controls of the H4 have been replaced with a more intuitive system based around one menu button and a single scroll-and-click selection wheel. The track-selection buttons double up to provide shortcut keys for some of the more commonly used functions — folder and file selection, playback speed (yes, you can slow down tracks, without pitch change, to learn your guitar licks), and recording format. The recording level and playback volume settings are controlled by dedicated buttons on the right and left panels respectively.

At the top are more solid-feeling mics than appeared on the H4. These are, again, configured for coincident stereo recording, but can be rotated between 90 and 120 degrees. Combi sockets on the bottom panel allow the connection of external mics, or line/DI sources, and these sockets can deliver 24V or 48V phantom power. The preamps have been upgraded; they’re not high-spec by studio standards, but are perfectly adequate for this sort of device. You can also connect a stereo mic via a mini-jack socket (with plug-in power), to use instead of the onboard mics.

As well as the line/headphone output, there’s now a small speaker on the rear. This isn’t for serious monitoring, of course, but it’s a useful addition that brings the Zoom into line with more recent competition. It means you don’t always need to use headphones or external speakers to check things are operating as they should, or to locate a specific track or location within a track. Power comes in via the included adaptor, or a pair of AA batteries.

Like the H4, you can record in different file formats, with a range of MP3 and WAV options, from the cruddiest, media-efficient MP3 to 24-bit, 96kHz WAVs. Usefully, you can record broadcast WAVs, with markers for use when navigating or editing audio files, or burning CDs. All this is recorded to SD card (a 1GB card is included).

Four Play?
The H4’s four-track mixer enabled you to do basic overdubbing, and to apply effects to your recordings, but despite having two mics and two external inputs, it wasn’t capable of simultaneous four-track recording. With the H4N, you still get a multitrack mixer, but the onboard mics and external inputs can be used simultaneously. Because the onboard mics are configured for stereo, your four-track options can seem limited, but you could bypass them using the mini-jack input and a splitter cable for a pair of battery-powered mono mics. Even without this, there are plenty of possibilities. A number of applications are suggested in the detailed manual, and there is plenty more potential. Capturing jam sessions in stereo while, say, DI’ing keyboard and bass/guitar parts, is easy; or you could similarly take a feed off an FOH desk and DI a couple of instruments or set up a pair of ambient or audience mics to give you more options in post production. It also opens up the possibility of surround-sound recording, and it might prove useful for applications such as impulse-response capture.

Putting the H4N into four-track mode is as simple as clicking the menu button, scrolling to ‘Mode’ and clicking, then selecting ‘4CH’ and clicking again. A similar approach is used to set it back to stereo. There’s also an ‘MTR’ multi-tracker mode, which allows you to record mono or stereo sources to each of your four tracks, apply effects to and balance those tracks, and create a stereo bounce.

Bells & Whistles
There’s plenty more on offer too, from compressors and low-cut filters, to guitar amp and cabinet emulations (not the most authentic out there, but certainly passable for demo purposes), and distortion and delay-based effects.

As with so many of Zoom’s products, there’s literally too much to go into in detail in a review of this length, and I’d recommend visiting Zoom’s web site if you’re genuinely curious about the range and quality on offer. Suffice it to say that I’ve called these functions ‘bells & whistles’ as I suspect they won’t sway most people’s decision to purchase. Even if you don’t plan to use these sort of facilities for mixing, they do provide a convenient means for headphone-clad guitar and bass practising.

One really useful ‘whistle’ is the four-in, two-out 24-bit, 96kHz-capable audio interface capability, and you even get a copy of Steinberg’s Cubase LE4 DAW software for Mac and PC thrown in — which makes the package more than enough to get a would-be home recordist started. It wouldn’t be my first choice as a hardware interface (this is, after all, designed with location recording applications in mind) but it’s certainly very usable.

Sound Choice?
In terms of ergonomics and functionality, then, the H4 has undergone quite a transformation to acquire the extra ‘N’ (which stands for ‘next’ — probably my only real gripe!). But what of the sound quality? Well, that’s improved too. Tackling the handling-noise issues of the H4 and upgrading the external mic preamps makes quite a difference. Using the preamps with a pair of AKG C451s, I was able to capture a perfectly usable sound in the studio. The onboard mics are definitely an improvement, and comparable with those on other portable recorders in this price range. The two stereo-width settings also give a useful option when trying to achieve separation between two sources, or simply recording something like an acoustic guitar part in stereo, while leaving a ‘hole’ in the middle for a vocal.

Conclusion
I’m a big fan of the H4N, and found very little to dislike about it. While there are more ‘professional’ portable recorders out there, you’d be hard pushed to find something that’s better on sound quality alone. This product is also aimed at a very different market, where it compares very favourably with the competition. The H4N is justifiably a little pricier than its H-series predecessors, given the improvements that have been made, but although there’s a lot of ‘bonus’ functionality I can’t imagine using, you’re not paying a premium for it. If you want a good handheld recorder, this should definitely be on your shortlist; and if you want simultaneous four-track recording thrown in, it will be a very short list indeed!

How to Synchronize ZOOM H4 Audio with External Track

Saturday, November 21, 2009

It 'important to realize that even if the oscillators sample may vary from one another, they tend to be extremely accurate in time, we are referring to themselves. This means that if you know what the clock speed of your recorder audio''autres sample clock of the camera, so a single correction factor will both return path for the synchronization.

A simple procedure is described below, using freeware programs, for calculating the correction factor necessary for your particular record. Necessary programs (all free):

1) AoA audio Extractor --- (not necessary if you can extract the audio track from a video recording in your NLE)
2) Audacity , a free audio editor
3) Switch , a free audio file type converter

Step 1: Set up your camera and audio recorder next to each other, and start both running

Step 2: Make a good audio 'clapperboard' point by tapping a pencil firmly onto a hard surface, as close to both camera and recorder mics as possible. This will cause a fast 'edge' to become the reference point, which will be useful later.

Step3: Let both devices run for at least 10 minutes. 20 minutes are better, but not essential.
At the end of the period, (timing not critical), make a second similar 'clapperboard' reference point. Allow a few more seconds recording, and then stop both devices.

Step 4: Download the video from the camera, and the audio from the recorder to your computer.

Step 5: Open the video file in 'AoA audio Extractor', and extract the audio from the video. Convert this audio file (if necessary) to a 48KHz 16 bit LPCM (wav) file, using the 'Switch' program linked to above. This file will be your reference audio file.

Step 6: Open the WAV file saved in the previous step in 'Audacity' - a free audio editor.

It is now necessary to save only the part of the file between the two 'clapperboard' references, which hopefully stand out clearly (if you hit the pencil hard enough in steps 2 and 3!).

This must be done accurately, to within 100th of a second, or better.

Click and drag the file to highlight the beginning section, including the first 'clapperboard' waveform. Use the 'fit selection to window' tool (immediately to the right of the 'zoom' tools) to magnify. Delete as much as possible before the 'clapper' reference. Repeat the operation until you can clearly identify the first distinct waveform of the 'clapper' reference waveform. Click, hold and place the cursor directly over the first full (clipped) waveform, where it crosses the centre line. Delete every thing to the left of that point, by clicking and dragging to highlight, and then deleting with the scissors tool.

Step 7: Repeat the above procedure for the end part of the waveform, again using the start of the second 'clapper' waveform as your reference cutting point. In this case, cut everything to the right of your selected reference point (not the left, as in the first case.)

Step 8: It is necessary to record the exact length of this new cropped waveform. This information is listed at the bottom of the window, but in a rather inappropriate format. Locate the toolbar
at the top of the window, click 'Edit'-'select all' and then 'Effects'-'change tempo' . Note the length of the file in seconds in the right hand box (the left hand box is greyed out).

Record this figure. It is the reference file length

Step 9: It is necessary to convert the file recorded on the audio recorder into an identical format to the camera audio track, namely 48 KHz 16 bit PCM. If the track is not already in this format, open it in Switch, a free file transfer program, and select the output encoding as 48 KHz 16 bit, mono or stereo to fit your audio file. This program will then convert whatever format your input file is (MP3, WMA, 44.1 KHz PCM, etc) into the required 48 KHz, 16 bit format required.

Step 10: Repeat the procedures in steps 6 and 7 for this new file. Edit the 'clapper' points with as much accuracy as before, but notice that the 'clapper' waveform will appear different from the first, although hopefully with as clearly defined first ' zero crossing' point.

Step 11: Repeat the procedure in step 8, and you will notice that the overall file length is different.
Overwrite the original file length into the right hand box, and take careful note of the resulting figure in the percent change box. Make sure you record whether it is a plus or minus value - it could be either! This is the most important figure, because it represents the percentage variation between the two units.

Once you have obtained this value, simply apply it to all files recorded with the same recorder and this camera. Providing you can align the start of the file with a single 'clapperboard' mark, there is no need to repeat the rest. Simply change the length of the external audio file by the correct percentage value, to allow the two audio tracks to remain synchronised.

It may seem a long winded process, but it only needs to be done once, and could then save quite a lot of time, against the option of trying to align tracks manually in your NLE, in small sections.

You may of course wish to use an alternative audio editor, and the details of this precedure may then be slightly different, but the principle remains the same.

Friday, November 13, 2009

Unlike other flash-based recorders, the Zoom H4 features both a track or two to four-track recorder. Four track mode allows simultaneous playback of four tracks and recording of two songs. All four tracks are recorded, you can mix and bounce to mono or stereo, then add more tracks. You can add effects such as the emulation of guitar amps, chorus, compression or delay. Other unique features are a metronome and guitar tuner. In stereo mode, the Zoom H4 can record 16-bit or 24-bit WAV files at 44.1 kHz, 48 kHz or 96 kHz. A full range of MP3 bit rates are also available. Four modes of road, the unit records 16-bit/44.1 kHz.

Built in H4 are two studio-quality electret condenser cardioid microphones in X / Y pattern for true stereo recording. Bar-top caps protect damage to the microphone and foam windscreen is supplied for external use. Documentation H4 Secure Digital (SD). A 128 MB SD card is included. With a 2GB card, the H4 provides up to 380 minutes of recording in 16-bit mode (CD quality), and 34 hours in MP3 stereo mode.

This versatile machine can operate as a USB audio interface, which allows you to record instruments and vocals to your computer. The H4 comes with Steinberg Cubase LE is a multitrack recording software that works with Windows and Mac So for $ 299, you get a workstation and a digital audio tape recorder two-track/four-track. Audio must be 16-bit, 44.1 kHz or 48 kHz mode USB interface. Zoom offers a USB cable and a Handy USB / Cubase LE start guide. The device uses two AA batteries or power adapter included. Battery-powered continuous recording time is four hours, shorter, with phantom power switched on. The dimensions are 2.75 centimeters x 5.22 centimeters x 1.38 cm.

In terms of H4 is a backlit 128 x 64 pixel LCD screen, buttons sampling rates or indicators, a stereo with four modes LED track, record button and a slider button to select menu, play / pause, or modify the file. You press the record button once to set the levels and press the button again for registration. Arranged along the front left is a stereo jack for output as a line 1/8-inch, 1/8-inch stereo headphone jack, wheel, headphone volume, on / off switch and a mini-USB port.

How to record live presentations by Zoom H4

Tuesday, November 10, 2009

The recording of a presentation can be difficult. Not only will you have the challenge of capturing the audience's questions, it is also generally have a PowerPoint presentation that everyone is watching, and the hum of a projector and a microphone that wants to enter a room. Although you can use a variety of digital recorders, digital recorders Olympus creaks a bit 'economic, like bacon frying in the worst case. (To hear a track record of a higher end Olympus digital recorder, listen to this.)

I experimented with other recorders like the Zoom H2 or Edirol or Marantz. I am sure that every time you start spending $ 200 on a tape recorder, the increase in sound quality.

The costs for my Zoom H4
I like the Zoom H4, not only for the sound quality, it also doubles as an audio interface for your computer. In other words, you can use the Zoom H4, a USB microphone to record Camtasia or Captivate tutorials - and the sound quality sounds great. And if you want to record interviews in person, zoom microphone to record the sound is better than many external XLR microphone (that plugs into it). But it is also possible to use an external microphone to put in front of someone. This may be preferable at times. Since the zoom microphones are so sensitive, they will get every movement of his hand on the device.

My method for recording podcasts with Zoom H4
In this post, I share the method I used to record my last blog and podcasting the presentation of a local chapter of the STC. Moreover, since PodCamp SLC salt, I want my document techniques.You audio recording might want to spend a few days to familiarize themselves with the Zoom H4. Do not worry one of the four skills of song.

Tip: I recommend to buy audio equipment from the professionals. They have a lot of personalized cards and peripherals, which may be necessary, and vendors have experience with audio, if you have questions about what to buy.

Define and record audio
1. Insert the SD Memory Card 2GB Zoom.
2. Adjust the zoom of a recording in WAV format.
3. Activate the phantom power zoom to 48 volts.
4. Adjust the zoom to the mic input, rather than omnidirectional microphones.
5. Connect the adapter Phantom zoom.
6. Connect the adapter omni-directional lapel microphone phantom.
7. Drag the Zoom in custom-sewn belt clip large and attach to your belt. Tie-clip microphone a few inches below the chin of the presenter.
8. Make a big sign that says "Please repeat the questions from the audience."
9. Each time the audience asks a question, make the sign you made in step 8.
