Is it possible to record from speakers on mac?


When I enumerate all the recording sources using getRecordDriverInfo(), I only get microphone devices.

Do I miss something or it is not possible to record from speakers on mac?


Could I grab some more info, what are you trying to record?

getRecordDriverInfo() will only retrieve microphones as they are used to record external audio.


In the meantime, I found the “BlackHole” utility which allows to record the sound card output on mac.

Anyway, I was trying to follow this old article where the sound card output is used for visualization.

Now, even with “BlackHole” turned on, I still can’t manage to use the signal for FFT purposes. Will create a new post on the subject.
