Need Audio recorder for capturing from output of soundcard
Using Debian Jesie
I need something to record from my soundcard. I have tried audacity but not able to get it working. I need something that works. What are some good recording software that works in linux? I do google searches with not much luck. Mostly get hits for Audacity.I cna't get audio control set up properly for Audacity. It would be good to have more than one audio recorder anyway. Thanks, Joe |

If you have snd-aloop kernel module
Code:
find /lib/modules/`uname -r` | grep snd Example: ~/.asoundrc Code:
pcm.!default { Code:
modprobe snd-aloop Code:
ffmpeg -f alsa -i hw:1,1 -c:a aac -b:a 32k -vn OutFile.m4a Code:
mv ~/.asoundrc ~/.loop_asoundrc && modprobe -r snd-aloop |
I'd find out why AudacityŽ didn't work. (funny, they copy protected the name)
Using pulse, jack or alsa may be part of the issue?? lspci | grep -i AUDIO dmesg | grep -i sound |

I got Audacity to work today. I don't know why that is. I don't see what I did different. I chose monitor built-in audio analogue stereo. Yesterday Audacity kept freezing on me and I had to terminate it with kill. I also tried vlc today to record. Using view > advanced controls, > chose audio capture > built-in audio capture However when I played the file the sound was only a whisper. Xould hardly hear it. If I tried moniter built-in audio capture I get a bad sound while listening. I don't really understand pulse. |
When I think of the times I had problems with volume levels there were two issues. One was some setting like -20db that was checked. The other was I was using mic as input and not internal line passthrough to capture sound.

Pulse doesn't understand pulse.
I tend to use a pulseaudio over jackd configuration. When you need to do something fancy / odd you can use qjackctl to change the routes to get what you need. Otherwise you need the loop stuff and direct access. $ find /lib/modules/$(uname -r)/ -iname '*snd*loop*' Audacity can be pretty non-functional without a .asoundrc to tell it which end is up. Or other less than obvious configurations for other audio applications. Like hostname and /etc/hosts to be setup and configured, so the client and server model functions even though nothing else about it uses networking. Kids these days. |
Audacity works fine for me in Fedora 25 w/ pulse. It was a little tricky to set up, first visit was to the pulse audio volume control to choose Monitor as an input source (monitor devices weren't enabled by default for me) Then I had to fiddle with the Device toolbar in Audacity to set the audio host, recording device and playback device properly.
After those one-time setup steps I've been able to record anything that was playing sound without any problems. |
