Record sounds (Deezer, etc) in separate tracks

sudo apt-add-repository ppa:osmoma/audio-recorder
sudo apt-get update
sudo apt-get install audio-recorder


or preferably

sudo apt-add-repository ppa:osmoma/audio-recorder -y && sudo apt-get update && sudo apt-get install audio-recorder -y

 or even better, if apt-fast is installed

sudo apt-add-repository ppa:osmoma/audio-recorder -y && sudo apt-fast update && sudo apt-fast install audio-recorder -y


Start recording while playing Deezer or any sound played by the computer.

If listening to an album and want to get files separated according to the silence between them uncheck the Add option, and then edit Timer, which is a matter of trial an error, and changes should be made from case to case.

A good start would be adding in any case 'start if sound', so that a new file should be created when sound starts; but in order to have a new file (different from the previous sound), first the recorder must be made to stop when there is no sound. 'stop if silence' is not a good option, as it creates a lot of small useless files; a better option is 'stop if silence 1 sec.'; and 'stop if silence 0.5 sec.' may also be a good option. (This should be enough for the stated purpose. Using audio threshold timer commands seems to me more complicated.)



The files are saved in ~/Audio.

Changing volume level during recording is a bad idea, because the recorded sound is distorted.
