I know this is an old video, but thanks a LOT for this. I was struggling with getting into qjackctl and just needed an easy fix. Google returned tons of results, but this just made my day.

The Unix gray beards would be proud of you, well done.

Hey Kris, do you know if it’s possible to record from the output source at a speed that’s faster than the 1x real-time speed? But when it’s done recording, I still need the recorded file to playback at the original 1x speed. I just have a long 60 hour track that I need to record but I want to see if there’s a faster way to record the whole track that doesn’t require me to just run this for 60 hours straight. Does that make sense?

Even if you use a GUI to record, knowing a bit of background on how it is working behind the scenes is important. And as you said a script to quickly record would be really cool.

do you know how to record from two devices but in the same file. So record my microphone and the audio coming from headset. I have tried -f pulse -i 2 and -f pulse -i 1. It only records from from -i 2 (which ever one I put first)

hi! great video.
is there any way to sync audio captured from soundcard output (.monitor) and audio captured by the mics?

[StefanoPapaleo-TS]

Awesome. Makes things easier for all those non-Jack programs or just something quick & dirty. Thanks!

Good to hide the most important part, the commands behind your preview.

Kris, thank you for the tutorial...Would you happen to plan on a tutorial on how to record multiple sources into a single file (would that eliminate the possible out of sync situation)?
