'ffmpeg' -loglevel "verbose" -v 99 -i - -c:a pcm_f32le "%f" how is this it like making a 24-(8x3)bit-image out of 8-bit(256 color) data? 😕😖 but do appreciate the honesty about the nauseating waveforms earlier.. ...

This works fine for me: ffmpeg -i - -c:a pcm_f32le "%f.wav" Produces: General Complete name : myfile.wav Format : Wave File size : 5.05 MiB Duration : 30 s 0 ms Overall bit rate mode : Constant Overall bit rate : 1 411 kb/s ...

... so that the resulting music, with its possible tied notes and harmony is also preserved. If I take the original selection, export it and use ffmpeg or rubberband to get the pitch change, it does it perfectly, a beautiful pitch change to the exact percentage requested and with the same duration, ...

You could perhaps write a Python script to send commands to Audacity to:
1) Run the labels to chapters plug-in.
2) Export the audio as MP3

and then:
3) Sleep long enough for the export to complete
4) Run the FFmpeg command.

That fixed the plug-in installer! Thank you. My current steps are: Run the labels to chapters plug-in. Export the audio to mp3. in terminal, run ./ffmpeg -i /Users/vmarks/Downloads/ai\ pod/ai\ pod\ destri.mp3 -i /Users/vmarks/Downloads/ai\ pod/metadata.txt -map_metadata 1 -codec copy -id3v2_version ...

thanks, it worked!
