At the end of WWII, the Soviet Union shifted its censorship into high gear in order to minimize the corrupting influence of the West. The punishment for disseminating banned materials could be imprisonment in a gulag, or even death. But that didn’t stop the enterprising, innovative people of the former USSR. @TheConversationUS explains “bone music,” where recordings of Ella Fitzgerald and Elvis were etched into used X-ray film. “The music … suggested that a different sort of life is possible, beyond the strictures of Communist officials. How could a political system that prohibited beautiful music, many asked, possibly merit the allegiance of its citizens?”

The ConversationWhen Elvis and Ella were pressed onto X-rays – the subversive legacy of Soviet ‘bone music’The bizarre, homemade technology became a way to skirt censors in the Soviet Union – and even played an indirect role in its dissolution.

Dear sound/audio folks and engineers,

[Update: just for clarity: I'm looking for a command line utility that will help me decide which of 70 audio recordings need amplification/compression/normalization. Something that can print out media stats like average loudness, or something like that]

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!!

I am making a very nice recording, this time in the K Desktop Environment, on one of my master tapes.
I'm recording Herbie Hancock I'll make another post separately about that. The manner in which the Bass player is handling the double bass is amazing!
