How can I obtain the audio stream that I hear in speaker system or in earphones?
Let assume that we have the following situation: we have a sound in the speaker systems or in earphones, maybe we play an audio CD, some mp3's or maybe a movie, etc.
All I know is that the sound goes through sound card to speaker system or in earphones, no matter the source.
How can I obtain the audio stream that I hear in speaker system or in earphones?
I would like to write an application that record and analyze the audio stream that I hear in my speaker system or in earphones.
My OS is Ubuntu 10.04.
If you have a recommendation like "try to use ALSA", please provide more details like "in alsa-utils you have a class Class_Name, with the following function Funcation1, etc. Try to use the Function5 as in the following example".
Any help is appreciated.
