Is there any advanced audio mixer where I can have more control of my microphones (audio input)?
There's almost no options on alsamixer and the default pulseaudio mixer. Also, I can only see stereo options for my microphone (digital stereo, normal stereo, ...). I would like to change things like frequency, add noise cancellation and maybe other filters at the OS level.
I'm picking up too much background noise.
The most complete recording, editing, and audio mixer software is Ardour. This software is based on Jack rather than PulseAudio sound server.
can be installed from the Software Center but it will likely better be integrated in the Ubuntu Studio flavour of Ubuntu.
If it is only a single or few LADSPA plugins we can also integrate them to the default Pulseaudio server:
For editing (but not for real-time effects) we may have a look at Audacity which also nicely integrates additionally installed LADSPA plugins.
