[Solved] SOX not recording

[rick71]

Raspberry Pi 3+, Bullseye, Sox 14.4.2, Audacity 2.4.2, USB soundcard. I'm trying to produce timestamed sound files, preferably in the file name, but that can be edited later.

AUDIODEV=hw:1 rec -r 44100 TX.ogg silence 1 3.0 5% 1 7.0 5% : newfile : restart

record command starts, creates TX001.ogg, timer shows the script running, but it seems nothing is recorded and nothing is saved.

When using Audacity, Software Activated recording enabled, input is captured and can be saved/exported.. Audacity is showing input is on the left channel.

Can anyone point out what I may be doing wrong?
Thanks.

Adding AUDIODRIVER=alsa immediately after AUDIODEV=hw:1 has allowed some audio to be recorded, saved and the script restarted. I'll have to play with the numbers to get the recording start/save/restart working properly. I'll also have to look into saving the file with a timestamp name instead of an incremented name.

I do believe that Buster is abut to reach it's end of life cycle in a couple of months. I'd strongly recommend that that the OP look into either Debian 1o(buster) or Debian 12(bookworm).


Debian 10 Buster reaches it's EOL aon June 30th of this year.
Debian 11 (Bulleye) Reaches its EOL on June 30th 2026.
Debian 12 (bbokworm) 12 (BookWorm) June 30th,2028

So I'd strongly recommend that the OP consider one of the last two releases that are listed up above.

This is what I use.

Code: Select all

sox -t alsa sysdefault:CARD=A900 ./record.wav silence 1 0.1 5% 1 2.0 5%

Run

Code: Select all

arecord -L

to get the name of the mic you want to use. This is a better way as hw1 might change it's card on reboot unless you've previously set your card loading order.

Wav gave me the best results while recording and it's very easy to re-encode later.

Stop posting irrelevant comments. OP is using Bullseye.

I have adjusted the recording numbers and prepared a bash script. All seems to be working for now, including saving file with the timestamp in the file name..

Thanks all.
