If you use a tilt EQ you chose a centre frequency, if you use a shelving filter, you chose a start frequency, but if you move the graph, they are the same. If you manipulate the frequencies you automatically manipulate the amplitude/level of the signal, it makes no difference what approach you chose. Changing the level of the frequencies requires to adjust the level of the audio signal. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
