Full Version: Sample rate conversion = pops and clicks?

Howdy,

I'm not sure where to post this, so here goes:

I have a bunch of MP3's encoded at 160-192 and I am attempting to broadcast using shoutcast and oddcast (using the LAME encoder to re-encode and send to shoutcast). I can stream without a problem at 44100hz 128K, but I decided to get all creative and stream 96K and cut the sample rate to 32000. Unfortunalty this produces a ton of pops and clicks to the music, a very unexpected distortion IMO. I expected ringing or fuz from a bad sample rate conversion, but pops and clicks??

Can someone explain to me why this would happening? And related, does it do any good to cut the sample rate in order to keep the encoder from wasting bandwidth on frequencies I can't hear (not on these speakers anyway)?

Seems like a bug in whatever does the rate conversion.

Resampling indeed helps efficiency a bit.
