You may know that no real-life room is perfect in terms of wavelength neutrality. That means that the music is "destroyed" by reflections and absorption of certain wavelengths by your room. Also no speaker behaves perfect. By applying a realtime-filtering you can adjust the music signal and by this compensate for negative effects. Goal: Better sound :-)

Quote:Which filters would you want to apply and how many filter coefficients would be useful for your purposes?

I'd apply one filter per room. The number of coefficients depend on a lot of parameters. I cannot answer that before I could try it with MinimStreamer :-)

Quote:How would you determine those filter coefficients?

I think I'll start here
