Using audacity to record streaming audio?

Postby tsreyb on Fri Jun 06, 2014 11:51 am

I used to use audacity in Windows to record streaming audio - it was actually just an analog recording of what is sent to the speakers, but it was more than good enough for me. Audacity used as its input device the windows WASAPI interface.

In mint I'm playing the audio stream with banshee. I've got audacity running, but when I record I get nothing for all input choices - except for a mic input device, which is very low quality and records room sounds as well). I tried all possible input devices known to audacity on this system:

HDA Intel MID: ALC887 Analog (hw:0,0)
HDA Intel MID: ALC887 Alt Analog (hw:0,2): Front Mic:0
HDA Intel MID: ALC887 Alt Analog (hw:0,2): Rear Mic:0
HDA Intel MID: ALC887 Alt Analog (hw:0,2): Line:0
HDA Intel MID: ALC887 Alt Analog (hw:0,2): Front Mic:1
HDA Intel MID: ALC887 Alt Analog (hw:0,2): Rear Mic:1
HDA Intel MID: ALC887 Alt Analog (hw:0,2): Line:1
IVTV-0: Hauppauge WinTV PVR-150 (hw:2,0): Front Mic:0
IVTV-0: Hauppauge WinTV PVR-150 (hw:2,0): Rear Mic:0
IVTV-0: Hauppauge WinTV PVR-150 (hw:2,0): Line:0
IVTV-0: Hauppauge WinTV PVR-150 (hw:2,0): Front Mic:1
IVTV-0: Hauppauge WinTV PVR-150 (hw:2,0): Rear Mic:1
IVTV-0: Hauppauge WinTV PVR-150 (hw:2,0): Line:1
sysdefault: Front Mic:0
sysdefault: Rear Mic:0
sysdefault: Line:0
sysdefault: Front Mic:1
sysdefault: Rear Mic:1
sysdefault: Line:1
pulse: Front Mic:0
pulse: Rear Mic:0
pulse: Line:0
pulse: Front Mic:1
pulse: Rear Mic:1
pulse: Line:1
default: Front Mic:0
default: Rear Mic:0
default: Line:0
default: Front Mic:1
default: Rear Mic:1
default: Line:1



.. all of them record nothing but silence (other than "sysdefault: Front Mic:0", as I described previously)



has anybody had success recording a stream with audacity (or any other tool)?

Try this:

1) Open Terminal and install PulseAudio Volume Control by issuing the following command:

Code: Select all
sudo apt-get install pavucontrol

2) Launch the PulseAudio Volume Control program by typing "pavucontrol" (without quotes) in Terminal and hitting ENTER.

3) In PulseAudio Volume Control, click on the "Input Devices" tab

4) Make sure to mute all unwanted sources of sound input

5) Click on the "Show" radio button and change the setting from "All Except Monitors" to "Monitors"

6) Play the music file in Banshee, and make sure one of the Monitors in Volume Control (in my case, it was called "Monitor of Built-in Audio Analog Stereo") is picking up the sound

7) For the Monitor that is picking up your sound, click on the green check button to "Set as fallback"

8 ) Launch Audacity and record

That allowed me to record music coming out of my computer speakers in Audacity without it sounding tinny and low (like a cheap mic).

Newbie? Does an external mic have to be plugged into the PC? I have a Vostro 220 w/o a mic and would like to try to record sound from a U-tube video. How would I do that if its even possible. Mods if a new thread is required please let me know. Thanks -AD
