I appologize for the non-compressed AIFFs of Seefeels new CD5. I converted them to .au's (160K for those of you keeping score) tonight so dig it at: http://hyperreal.com/music/artists/seefeel/seefeel.html I'll convert the other sound files later this week. -- Brian "Pepsi, just fucking drink it, man!" http://sparrow.bio.indiana.edu/brian/me bhostetl@silver.ucs.indiana.edu

Sorry to barge in like this, considering i've been off this list for a while, but didn't Brian Behlendorf suggested MPEG as the standard for audio on hyperreal? Also, compressed AIFF are a pain on any other platform than Mac, while compressed (ADPCM) wav can be played on all platforms (on PC just by using media player, and for Mac, there is a player on stanford). On data CD technology (like CD-i, CDROM etc...) ADPCM .wav is what is used and sometimes MPEG (much more used for video) to compress audio, so i would suggest one or the other instead of those horrible sounding .au files. For MPEG, one has to consider what bitrate will be used, and from that, what level (1, 2 or 3) of the MPEG 1 audio support will be used. With level 3, one can get the same file size as .au, but with very high fidelity. It does take over an hour to compress a complete song on a machine without DSP however. Level 1 can be done in realtime. For ADPCM, it always yield 4:1 compression, but it can be done aon a 22KHz file instead of 44KHz, so it will give 8:1, which is almost as small as u-law .au files, but with a much higher quality (level 2 mpeg-1 type of quality for that type of bitrate). 44KHz adpcm gives equivalent results to level 3 mpeg-1 on the same type of bitrate, but is realtime in opposition to mpeg. The shear number of platforms that can do realtime ADPCM encoding and decoding would suggest we use this, but if we want to go with 16:1 compression rates instead of 8:1 then MPEG level 3 is the only way to achieve this. Note that a pentium 90 is required to play realtime an MPEG file with a full level3 decoding. So, any comments?
