[alsa-devel] app-internal volume control

Hi,

might be a dumb question for people knowing the externals of Alsa but I'm not sure :-(

What is the best practice to control the volume of a Linux application? I could control Alsa'x mixer for Master or PCM but that looks like a bad thing to do since it changes the volume for every other app as well.

Is there another mixer I could use which is application specific? Or do I need to implement an application internal filter to control the volume by modifying the audio stream?

Thanks, Wolfgang
