[gst-devel] Help needed on changing frequencies of equalizer

[Maarten Bosmans]

I'm not sure I quite follow you.

You can just choose either system of 10 bands and set the
centerfrequencies of the bands in the GStreamer equalizer to those
frequencies. You can then fix the bandwidth, or better yet, fix the
Q-factor of each band to a reasonable value.

In every graphic equalizer there is some overlap between the bands,
that's no problem.
