I'm experiencing little to no damping of acoustic echo from the echo cancellor and I can't figure out why so far. I thought I should try the echo_diagnostic tool so I built libspeex.dll and libspeexdsp.dll with the DUMP_ECHO_CANCEL_DATA flag, but I'm not getting any output files at runtime. Any ideas?
