When talking data rate in MP3 terms usually we speak of the compressed data rate (as is usually the case with JPEG image files). The data rate that you were speaking of in your example is the decompressed raw PCM data rate. In MP3 terms stating that a file is 192kbps means that its fixed or aggregate compressed data rate (in the case of variable bit rate compression) averages to 192kbps. And for what it's worth mp3 coding is limited to 32, 44.1 and 48 kHz sample rates, for higher sample rates other audio file formats must be used. -- Rob Studdert HURSTVILLE AUSTRALIA Tel +61-2-9554-4110 UTC(GMT) +10 Hours [EMAIL PROTECTED] http://home.swiftdsl.com.au/~distudio//publications/ Pentax user since 1986, PDMLer since 1998 -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
