Audacity Forum

Hi Steve, Sorry to bother you again, but I think the playback problem could be related to my MOTU sound card. I exported the recorded file in 16-bit WAV, then played it back using several WAV players, and audio is always 24-bit at the output. So probably the MOTU is doing something wrong... I'll tal...

Hi Steve,

I got the confirmation by one of my colleagues that the audio I recorded is really 16-bit. So we need to look at the playback chain... Could this be caused by Portaudio ?

In the meantime, I'll try to playback the exported WAV file with VLC.

Do you know any software that can read WAV files and display the audio samples with their values, like in an Excel spreadsheet ?

Am I able to see the audio samples values directly in Audacity's GUI ? Or the only way is to export in WAV ?

Both dither control are already set to "None".

By the way I also tried to disable everything in "Preferences/Effects", but still not working.

Hi Steve, I was able to make the test I described previously and I think I have some good explanations here. I recorded 16-bit PCM audio in Audacity, and when played back I obtained 24-bit audio. I have some equipment to monitor that the input PCM audio is really 16-bit, and that it is 24-bit at the...

Again, I want to remind you that compressed audio (or non-PCM audio) is carried through "standard" PCM audio samples. The only difference is how the sample values are coded. PCM audio is a linear coding, while compressed audio samples are defined by a specific encoding. Audacity doesn't know that co...

First, I don't know if the problem is at the record or playback stage. What I know is that my MOTU sound card is 24-bit transparent (I've had several discussions with them in the past). Again, I am feeding AC-3 audio (coded on 16-bit) to the system (MOTU + Audacity). I record the signal, then I play...

I went back on Audacity 1.3.11 (Beta) using MME drivers, and I did some recording tests with compressed audio mapped on 16-bit. I changed my project settings to 16-bit resolution, at 48k. My MOTU is also set to 48k. I still cannot playback the original audio "as is", it seems to be altered by the so...

Is it true to say that if Portaudio eventually supports 24-bit on Windows, Audacity will automatically support 24-bit ?

I will try to push a bit on Portaudio to know if this is going to be fixed soon...
