What sampling rate and bitrate should I use?
The standard for the a.b.s.mp3 newsgroup is 44.1KHz sampling rate, 128kbits/sec for Stereo music files. This is considered to be near cd-quality and of a manageable size for Usenet. Of course higher bitrates *can* produce higher quality MP3s in some cases, but 128/44 is high quality while not being too bloated for the MP3 newsgroups.
