[Freeswitch-users] polyphase lowpass filter

[e schmidbauer]

thanks for the tip...i figured it out....changed line
"lame_set_brate(context->gfp, 24 * (handle->samplerate / 8000) *
handle->channels);" to "lame_set_brate(context->gfp, 24);" and added line
"lame_set_lowpassfreq(context->gfp,0);"
not sure if everyone wants it configured this way....i find that this config
does not skip when broadcasting to icecast. thanks again.
