Capture sound from soundcard - tutorials are close but not quite
Hello,
I'm running Ubuntu Intrepid Ibid running kernel 2.6.27-14-generic on a Toshiba laptop. I'm trying to capture sound from a radio broadcast from NHK here in Japan and I can't quite get it. The broadcast is initiated from a Flash object so I can't use streamripper. I can open PulseAudio volume controls in Gnome and I switched my input source in PulseAudio Device Controller to 'Monitor Source of ALSA PCM on front:0 (CONEXANT Analog) via DMA' and I can see the sound output in Gnome. When I try to record from arecord I'm still getting a blank file with no sound. How do I tell arecord how to use the monitor driver? Thanks |

One person mentions a simple solution... Route autio out to autio in, physical route. Simple yet...Well yet ugly. |
If I understand well, you have sound on Line In, and you want to capture that to a file, correct?
If you are using arecord, issue these commands first: Code:
/usr/bin/amixer -c 0 sset 'Line',0 100%,100% mute capt After you issued these commands, do: Code:
arecord -r 8 -D plughw:0,0 If you see mainly '{' and '|' characters on your screen, you are NOT capturing any sound. But that is unlikely. If you see the screen full of garbage, you are capturing. So choose a sample rate, resolution and pipe the output in your file: Code:
arecord -f CD -D plughw:0,0 > myaudiofile.wav jlinkels |
