I played live last night and recorded my set in Rack. Due to how I shut down my computer at the end, I ended up with a huge stereo 24-buit 44.1khz wav file.
Any simple way to turn that into a WAV (or other format) file?
People often use Reaper or ffmpeg.

I have FFMPEG and learned how to add a header to a PCM file. But the result is garbage. According to the recorder I use - the Nysthi Recorder 2 - it saves as 24-bit PCM WAV files. So when I slammed the lid on my laptop, it didn’t get a chance to convert to WAV.
Does the PCM format match the output for that recorder?
try with REAPER
Audacity will also convert many a format to many other formats
Audacity will work fine. VLC Player can do it also.
One thing still bothers me: you have a wav file and you want to convert it to a… wav file? Do you need to convert at all?
Audacity does not autodetect the encoding used in the temporary PCM file that can be found if rack is killed via taskmanager while recording using the NYSTHI recorder 2.
I used these NYSTHI Recorder 2 settings:
killed rack while recording, and recovered the PCM using Audacity:
In audacity, File .. Import .. Raw Data, These settings seem to do it:
32 bit float, Little Endian, 2 channels, match VCV sample rate used when recording.

Did you ever manage to get this working ? Or did you give up ?
If you stop the recorder in an unusual way, you could find a PCM 32bit stereo file on disk.
let’s say the file is named 202601291210_GT.000.pcm. you can easily convert in WAV 24bit format using the FFMPEG command
ffmpeg -f f32le -ar SAMPLINGRATEINYOURVCVRACK -ac 2 -i 202601291210_GT.000.pcm -acodec pcm_s24le 202601291210_GT.000.pcm.wav
(you must use the sampling rate you used in VCVRack during recording!)
example in mine I have 48khz
ffmpeg -f f32le -ar 48000 -ac 2 -i 202601291210_GT.000.pcm -acodec pcm_s24le 202601291210_GT.000.pcm.wav

Thanks, Antonio - that command line worked I thought I had it right but I missed one or more of the necessary flags.
