search for: bandlimited

I am totally new to icecast, and would appreciate a pointer in the right direction. My application is to encode audio (at the linux server) at a low bit rate, say ~16 kbps, for transmission to a decoder at another location. The audio source will be bandlimited (basically voice grade circuit such as you'd find in a telephone application.) The decoder end (connected via a TCP/IP session) would be a Windows CE 3.0 machine which may be limited to MP3 decode format. I've looked through what documentation I could find on icecast and haven't see...

John, Thanks for the reply! You mentioned output sample rates should be 44100 or 48000, should I worry about input (Mic) Sample rates as well? (Currently I was requesting the sample rate on both ends to be 16000 samplesPerSecond, for ease of passing into the codec) Also, do you recommend any particular resampler that I should use, or are any of the ones out there probably okay, or should

Hi everyone, We just made an Opus 1.2.1 minor release to fix a relatively rare issue where the 1.2 encoder would wrongly assume a signal to be bandlimited to 12 kHz and not encode frequencies between 12 and 20 kHz. This only happens on a few clips, but it is good to update to avoid a potential loss of quality. There are no other changes compared to 1.2. Please report any problems. Cheers, Jean-Marc -------------- next part -------------- An H...

I don't know about the input side; I have personally only experienced being bitten by the output resampler. But it seems like a safe assumption that yes, the input side is equally broken. Any resampling code found on the 'net should be suitable as long as it sounds good, doesn't take too much CPU, and is compatible with your product's licensing/distribution terms. There are
