Audio Screen Recorder?

Post by Doug B »

Is there such a thing as an audio only screen recorder? Something that you could do things like record youtube,etc.
Like Simplescreenrecorder, but audio only.

Thanks

Depends on the Browser, Audio System (ALSA, Pulse, JACK) and Operating System in use.

Usually select System or Mix as the input source in audio mixer and then select the input source in Audacity.

Non of the settings show up where you indicated. I'm using a Lexicon Alpha External USB sound card.

I think it much depends what kind of audio setup you have. Asking from musicians, everybody assumes you have jack running.
If you have jack running, and pulseaudio, then recording PulseAudio JACK Sink will give you all 'normal' desktop audio stuff.

You can use any audio recording program (like Audacity) but you have to set up your audio properly.

On my systems I have jackd running all the time. It's my main sound system. It gets all the audio since ALSA is redirected to Pulseaudio and Pulseaudio outputs via jack_sink to jackd.

That's only half of the truth,

The other half is to direct everything (Pulseaudio's jack_sink and jack clients) not to system:playback but to a central jack_thru instance. I named it "main". "main" is the central point that I connect Audacity to, so I can record everything.

Yes, downloading a video and extracting its audio track by the use of a video editor or even ffmpeg is what I'm doing, if I'm interested in the video's music. Takes the same bandwidth but very less time compared to recording.

In general I don't watch videos online. Also my browser just can't play audio, which I'm happy for as I find it annoying when audio starts coming out of my speakers after entering some web-sites. Browser is Firefox, needs pulse audio, don't have it installed, don't like it. Even disabling auto-play won't work on some web-sites.

Instead I'm downloading and watch later offline.

And just in case you previewed a video but are only interested in its audio tracks you may simplify as such:

Code: Select all

 youtube-dl --no-playlist -x -f bestaudio URLofWanted

Great, thanks!

I assume this would save some bandwidth/download traffic...
