Hi all, I'm new to this list, Linux daily user near 3 years ago but pretty new in audio work and my mother-lang is french :) I'm looking for pointer about sound analysis, the principal aim is to be able to analyse sound system response. I have a friend who is sound technician, he is using a win32 apps to measure loudspeaker response, this apps uses Maximum Length Sequence measurement and FFT to avoid it. I have not found an equivalent tools running under linux, I've found fftw lib but don't know how to use it :o Is someone use real time analyser to align his sound system ? Thanks, Jody
