Hello,
I'm almost done, I'm learning but slowly...
I finally made everything working but I lack a mixer that work to make the
first real test.
I want a kind of BassMax on a mono speaker.
I first split the stereo into two mono channels
then, I apply a low pass on one the Left channel
Then, I apply a shifter (overtone one octave) on the left filtered channel
Then, I mix both channels
Here under my asound.conf
Why does my final mixer doesn't work ???
Is there a way to generate more harmonics (2nd, 3rd, 4th, ) I could only do
2nd
Best regards,
Jean
