found a strange bug in Ubuntu 24,10 when using a headset connecting by dongle. I don't get any sound without having the sound settings window open. As soon as I close the window the computer goes silent but the media continues to recieve the media stream.
When I open the window in settings the sound comes back.

I like the idea of workspaces so I can hide the window and still having it open.

Äänen Lumo

Welcome to discuss the past year and future of our sonic art space in Vallila!

May marks one year since Äänen Lumo started renting the space which is now known as Toinen Kerros.

We feel it is time for a moment of shared reflection and discussion on these past months and future possibilities.

Welcome all organisers, artists and audience alike!

Update: Thanks to @furicle for this suggestion. I think it's about perfect:

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!!

Trees become soft woodwinds, mountains resonate as deep notes, and the vehicle's speed influences the tempo, creating a unique, immersive #soundtrack for each trip.
