I'm not sure why there's a loss in quality either. What I did was record on my Zoom in MP3 format at 96 KBPS. After editing in Audacity, I export the project at 96 KPPS, and there is definitely a loss in quality. I'm doing the recordings in stereo and am exporting in Audacity in stereo (not joint stereo). I'm not sure whether the stereo choice exists on the Zoom; that's just the way I've been recording.

I'm not sure why there is a loss of quality when you export to mp3 files. Experiment and see what results you get. Are you making the original recordings as mp3 files or as wave files. Does the digital recorder give you a choice between recording monaural and stereo files? Are you making the original recordings monaural or stereo in format. I may be able to help further once I have the answers to these questions. Other list members may be able to help as well. But aside from what anyone tells you, experiment. Make a small recording of test material on the recorder, place the file on your computer, and try exporting it as mp3 files using different bit rates.

I'm wondering if I should set this recorderto 96 KBPS when recording. Then I'd edit the recording on my PC in Audacity. After which I'd export the file at, say, 128 KBPS, since there seems to be a loss of quality when I export at the same KBPS as what I recorded in.I'm recording myself reading a book that we're wanting to sell immediatelyon CDs, and, possibly, in MP3 format eventually. I'm also wondering whether the low-cut filter should be on or off on my Zoom H1 while recording.

You said in your question that you are going to record in Audacity. Earlier, you said you are going to record using a digital recorder. 96kbps is not a high quality recording setting. Are you recording for yourself? Are you satisfied with the sound? As far as I know, it doesn't matter what format you are using, 9600kbps is not a high quality recording and exporting to a 128kbps mp3 file would mean, as I understand it, that you are using a higher quality mp3 setting than the original recording. You can't improve the original recording by using a higher kbps setting in the Mp3 file. Please give details about what you intend to do. Are you using a digital recorder? Are you recording files formatted as stereo or monaural files. Are you transferring files from the digital recorder to the computer, then working with them in audacity? Are you asking about a 9600kbps rate because that's the rate you are using in the digital recorder?

If I decide to stick with Audacity, record at 96 KBPS, edit the project and export to 128 KBPS, should that give me a high-quality recording?

I intended to word the first paragraph as follows:Instead of working with enormous wave files, I would suggest that you try recording in a high quality mp3 format and editing using Mp3 Direct Cut. If you don't like the results for some reason, you can usewave files. If you wwant to work with wavefiles, then edit them in Audacity, which is not as easy or convenient as editing using Mp3 Direct Cut, then take the time to have these large files converted to Mp3 for their final form, that's your choice. I would strongly advise you not to assume things such as that a high quality wave file will yield better results than a high quality mp3 file for spokenword recordings. I won't discuss music recordings in this message. I doubt that anyone can tell the difference betweena 320kbps mp3 file of spoken word material and a high quality wave file. And since you intend to convert the material to mp3 anyway, even if there were any detectable difference, it would be lost when you convert the wave file to mp3. No recording program serves all purposes well. Audacity serves many purposes well. It is not as good a choice for editing mp3 files as Mp3 Direct cut where all you want to do is edit, not apply effects or perform other operations. Gene ----- Original Message ----- From: "Steve the Fiddle" <stevethefiddle@xxxxxxxxx> To: <audacity4blind@xxxxxxxxxxxxx> Sent: Saturday, October 13, 2012 8:56 AMI> I'd suggest recording at 44.1 / 16 PCM, and use a good fast flashcard. If the flash card can't keep up with the amount of data there will be bits missing from the recording or other peculiarities. 44.1 / 16 should give excellent quality without overly stressing the H1 or the flash card.

I have only two choices with the Zoom, either PCM Wav or MP3. If I choose PCM Wav, which sampling and bit rates should I go with? My choices are 44.1-16, 44.1-24, 48-16, 48-24, 96-16, and 96-24. After recording, I'd edit with Audacity.

In the mp3 options when saving, is the bit rate mode set to constant? If so you could set it to average, and see if this is an improvement. Unfortunately, there will be at least some loss in quality after decoding from and then re encoding to mp3 format.

When I edit the recordings, I'm quite okay with the sound quality. When, however, I export these projects back into MP3 format, 96 kbps, I find that the quality deteriorates. The recordings kind of sound tinny, like radio stations' web broadcasts used to sound like. Can I fix these MP3s somehow? Is there a particular equalizer that anyone would suggest that I use?
