Recently I have become involved with the analysis of birdsound audio and have been making recordings using a handycam and the video facility of the Canon EOS 7D DSLR. However these are a very ‘clunky’ ways of doing a simple task and wonder if anyone has found a reasonably cheap digital voice/audio recorder which does the job fairly well?
I’m not really planning to do ‘professional’ recordings but more to get reference material (so please don’t bother to re-open the ‘playback’ thread as it is not my intention to use it for this purpose!)
Any constructive ideas gratefully received,
Tom
You are right – I was confusing it with the H1 which is very new from what I can gather!

Using the inbuilt mics and 8-bit WAVs or MP3s should provide great quality for indoor recordings with any of these devices.
I do find that 24-bit WAVs do give me a bit of lee-way for post-processing my outdoor recordings, especially when I didn’t get the microphone gain just right (I’m often concentrating more on the visuals: if I was serious about this I’d have someone dedicated to monitoring the audio recording).
The Zoom H4 initially only supported SD cards (i.e. up to 2GB) but firmware updates did extend this to 4GB SDHC. At the same time the H2 support was also upgraded through firmware updates (again, I think 4GB is the limit for the H2). The later H4N is better in this regard, but might or might not be the most appropriate device for Tom.
I usually put a 4GB SDHC into my R09HR which is plenty for my use (even with 24-bit 48 kHz stereo WAVs, at ~1 GB/hour) but I know that 8GB cards also work.

We use H2 recorders to record music exams in Victoria. We can fit a whole day (around 6-7 hours) onto a single 2Gig SD card and the quality of the recordings is excellent. We don’t have to worry about playback on the units. One feature that might be annoying for some users is that you have to take the screw-on stand off to change SD cards.
I think there may be a limit to the capacity of card you can use, but I’m not sure.

I also use the R09HR, for field recordings (either with the internal mics or with a variety of external mics) in conjunction with video recorded with my DSLRs. It’s small, and can record in 24-bit WAV format for optimal quality (or MP3 if you’re desperate for space). It also timestamps each recording file, which is essential for my work. Earlier I used a Zoom H4 and the R09HR is much better for me. The newer H4N might be an option, although it is larger than the R09HR.
The H4 had issues with internal hum from the power supply affecting recordings, which some people hacked with hardware mods, but I was able to avoid it by using an external power supply (driven by a Canon BP-511A battery!). If I recall correctly the H2 had some issues with noise on external microphone input, but my info is probably out of date.
The H4 could be connected via USB to act as an external mic/XLR IO box for your computer, but I don’t need that. I just pop the SDHC card out of the bottom of the R09HR and transfer the files to the computer that way.
I do wish I had a good wind-break muffle for the R09HR, but using external mics avoids that issue.
The H2 wasn’t new in late 2008 when I got my R09HR, so I’m not sure where you got that from!

For oral histories in my job we use a digital recorder designed for music recording. The Edirol R09HR (possibly a later model available now as mine is 2 years old). It is very popular with oral historians because its easy to use and to upload to a computer and has good inbuilt microphones.
If anyone is seriously interested I have a 15 page guide booklet compiled for oral historians by John Hockney that I imagine he will be happy to share to another field of users.
The cost was $550 in 2008.

Would be interested in any replies you get as I am looking at the moment. The Zoom H2 is supposed to be good, but is very restricted in its playback options and is very new. The one I am looking at (but can find no reviews of as it is also very new) is Olympus WS750M which seems to do most of what I want – both recording notes in the field and hopefully bird calls and also the occasional playback! FOr me the ability to plug into a PC to transfer recordings is vital and both of these do that.
