I recently acquired a hand-held stereo linear PCM recorder for the purpose of recording different pipe organs. The recorder allows bit depths of 16 or 24 and sample rates of 44100, 48000 or 96000.

Having watched the primer videos at I know that there is no obvious advantage in distributing files with greater bit depth or sample rate than 16/44100 for playback. I am also aware that on a portable device the effective bit depth of the recording will not come close to 24 bit. Storage space on the device is not an issue for me with the availability of cheap, high-capacity SD cards.

My question is which combination of sample rate and bit depth settings are likely get the most out of what I assume is relatively common ADC hardware? For reference, the recorder is a TASCAM DR-05, which is a $100 device.

I've been using portable digital recorders with some pretense of quality for about 10 years. Or, should I say that about 10 years ago I bought a first generation M-Audio Microtrack, and have used it for any numbe of live recording assignments, since then.

It turns out that the Microtrack does 24/96 which I have used on occasion for technical reasons. The Microtrack has about  98 dB dynamic range in 24/96. It comes close to the theoretical 93 or so dB limit of 16 bits.  So we're talking 5 dB of headroom difference, which is not a lot in practical use. In general, I record at 16/44 and never have felt like the recorder was holding back the quality of my work.  

The phantom power feature has gotten a lot of use. The issue of battery life needs to be considered. If I'm recording for more than a few minutes, I hook up an outboard battery pack just to be sure.

The most important technical parts of any live recording that you can control are the microphones you choose and how you position them. I have found that relatively inexpensive small diaphragm microphones get the job done very nicely.

The quality of the musicianship and the acoustics of the room you are recording in are issues that strongly affect listener pleasure, and that you generally can't do a thing about them.
As is probably obvious by now, it's gone forever. I do have a backup that the shitty service provider sent me, but have no intention of putting it up anywhere. Honestly, I don't really care that much. It was fun while it lasted, but after a decade (plus the previous iterations plus the Rancid Snakepit), it was about time for it to be euthanized anyway.

Regardless, if someone else wants to start up a new board, I'll be happy to participate. I have no desire to own it again though. Being responsible for that place wasn't exactly hard work, but it was still a pain in the ass. I'd been trying to hand it off to someone else or just kill the damn thing for the last 7 or 8 years.

Sure, I can take a look, no problem, but as I said before it's unlikely to provide an answer.

Hi again. So, I decided to not bother you with that log cause it really looked unpromising and since you already said yourself that it won't probably help much, I just lived without AAD for a while.

But searching on google for squared images is absolutely not yielding the same results as AAD did! I miss that little piece of software! :)

Meanwhile, I also installed AAD on my laptop, which is also running x64 Win10. There, AAD is running fine...

I really want to figure out why it's not running on my desktop anymore though. Do you have any idea why the log file is not written at all to the temp folder, even when I start AAD with administrator rights?
What kind of microphone are you using? As far as I can see, the DR-05 claims to be able to handle input at 125 dB with its built-in mic, and if it is reasonably smart, it will align the 24-bit with sufficient headroom to capture anything the microphone can handle. (If then you clip in the digital domain, the signal was ruined already when it got that far.) But if you use an external microphone, then it is another story.

if you're making CDs (16/44.1) there's no reason for going higher than 44.1kHz.

That assumes that even portable recorders have good enough highpass filtering and do not start way below 22.05? Otherwise there is a theoretical - though I would suppose insignificant - improvement from downsampling later.
(Is that a battery-intensive operation? If so, could it be that a portable device has chosen a compromise solution?)

Good- I've been doing something similar.

Now can you answer the question?
I think I am going to get an ATH-M40X (certified refurbished), for 80 bucks, and add some brainwavz earpads as an upgrade. Total 100 bucks.
Yes, that's important. I don't know what kind of unit the recorder uses (such as dB, % etc), how about three files:
[1] maximum
[2] one step above minimum
[3] default (if any)?

Also, if the device has some sort of auto gain function, disable it for this test.
Thanks everyone for the replies.

Can you use the internal mic to record 10-20 seconds of silence (e.g. put the recorder in a drawer) in 24-bit 96k WAV and attach the file here?
What input level should I use for this test to be useful? Should I max the input level?

So the data from 1983 is what we need.
