I'm searching for a Audio DSP solution for ubuntu. I want to have the possibility to set some high pass and low pass filter to my 5.1 outputs. Low pass for the LFE and high pass for surround and center for instance.
I have "correctly" set up my installation and can change the volume on each channels but
- Changing the output on some channels will also change the overall output on others (it has probably something to do with upmixing??)
- I didn't find anything to set a high or low pass filter on one specific channel.
Until now I used the pulse equalizer and it does it's job but apply the filters on all channels at the same time. Is there any way to get this?
I'm surprised that there is no nice solution to tweak sound on linux.
Hope someone can help me there :)
