I'm not sure the controversy about the Audacity recording level is valid. I've been using Audacity for editing Redbook CD files ripped to 16-44.1 WAV and for 24-96 and 24-192 WAV LP recordings and Audacity converts everything to 32-bit float for processing. I haven't used Audacity to record directly but it makes sense that it records at 32-bit floating point resolution since that's how it's processing the file anyway.There's a discussion of that topic at the Audacity forum (linked below) and this is what I read:
"Audacity always records at 32-bit float, and then down-converts the recording to 16-bit if your Default Sample Format is 16-bit." In other words, it records at 32-bit float and then uses whatever bit-depth and sample rate you want.Not linked, but here's another discussion regarding trying to change the recording level to 16-bit:
https://forum.audacityteam.org/viewtopic.php?t=78179The image below shows an example of a CD file I ripped and opened in Audacity. You can see it's a 44.1Hz sample rate but it's now at 32-bit float resolution. My default sampling rate (Project Rate) is 96000 Hz and I specified WAV export format using 24-bit PCM Encoding.
I can also take a 24-96 or 24-192 WAV LP recording and export it to 16-44.1 WAV if I wanted. But it's being processed at 32-bit floating point resolution regardless of the original bit-depth of the recording.

Hi tk - I'd like to ask you a Qu re 'bits' - are you able to send to send a PM to me ... so I can respond.
Thanks,
Andy
Here's where you can set your default sample format bit rate. I have mine set for 96000 Hz sampling and 24 bit depth. But as shown in my previous post, Audacity takes my 24 bit file and converts it to 32-bit floating for processing even though I specified 24-bit as my default.
