[maemo-developers] Mixing audio streams

[From: Arek]

Hello,

What I'm trying to get is an application (or two separate apps, doesn't
really matter) that will be able to output two streams (from fmradio and
mic) separately (so some operations may be performed on them).

So far I'm trying to user fmradio and maemo-recorder to achieve this.
Running fmradio and setting Input Select (in alsamixer -c0) to Digital, let
me hear both fm output and mic at the same time. The problem is that those
are the same stream for the application, so I cannot manipulate them
separately. With this setting, however, maemo-recorder is able to record
only mic (without fm stream). What stuns me is that both fmradio (giving
both mic and fm) and maemo-recorder (giving just mic) use pulsesrc in
gstreamer.

Any ides how this (two separate streams) can be done?

I would really appreciate some help with this (part of a larger project,
blocking others).



Best regards / Med venlig hilsen / Z poważaniem,

Arek
