Sound on 🔊
Dear sound/audio folks and engineers,
I have a directory with 3.5GiB of audio files (chiefly opus & m4a) which are spoken word recordings.
Some of them are quite low, and some of them are quite dynamic such that it's a whisper at times and nearly a shout at other times.
I've processed a lot of them with #audacity's compressor filter or #ffmpeg (ffmpeg -i audio.m4a -filter:a "speechnorm=e=50:r=0.0001:l=1" audio-normalized.m4a), but there are some unprocessed files in the collection, which are a pain to individually find and fix.
Is there a way from the #CommandLine to detect the loudness and/or dynamic range of audio files so that I can automatically flag them for processing with ffmpeg?
Thanks!!
