... over and over. Data and aup files are together in the same file. a) LAME is now built-in into Audacity - it is only needed for exporting as MP3 b) FFmpeg is for import and export of addition audio formats - not neede for WAV exports c) If you get FFmpeg from the site or documentation recommends ...

Does anyone have a idea where i could pass "drc_scale" 0 option for ffmpeg in the audacity code? It always bothered me that ffmpeg defaults to the bad dynamic range compression for AC3 by default. Would be great to just fix this in audacity code for my ...

You don't have to "convert" them first. If you haven't done so already, download and install FFmpeg . It adds support for many/most audio formats. FYI - Audacity works with uncompressed PCM data so when you open a compressed file with Audacity (and with FFmpeg when ...

... nothing exotic here; it's just the typical onboard sound chip on my x399 motherboard. But out of impulse, I tried rebuilding with the '--without-ffmpeg' option and it launched properly. :o And it worked when I copied the build out to a laptop which is also running Debian 10. It's even more boggling ...

Then the script calls the underlying, 64-bit executable. But since there is no direct link between the app bundle and that 64-bit executable, ...
