Let me see if I can track it down... I agree with you, but 30Mhz! That is a very low clock for 256kbps decode. MIPS did very significantly outperform Intel at that time. http://www.mp3-tech.org/programmer/sources/amp-0_7_6.tgz http://www.mp3-tech.org/programmer/sources/amp-0_7_6.tgz Found it. An Indigo sat in the office for a time playing tunes from an NFS share we would populate. I eventually took it home to do the same thing. I forget how I parted ways with that old box. I am not inclined to build it at the moment, though it may well make for a great micro controller project one day.

Nice! Still compiles with a minor modification: added a break on the default case of a switch. Time signature is wrong when playing though. Edit: Fixed: add "frequency = frequency/2;" after the comment /* Set the output frequency */ in file audioIO_Linux.c

  Cool! I liked the quality output of that player at the time. Highs were clean. Does it still hold up? Maybe I will build it just for grins myself. Thanks for the tips.

    I can't critically evaluate the quality since I have no high quality mp3 nor Hi-Fi audio devices. An old recording of mine http://marcodiegomesquita.tripod.com/rda.mp3 http://marcodiegomesquita.tripod.com/rda.mp3 sounded with very unsaturated bass; which is good, I think I recorded/mastered it wrongly or the software I used at the time decoded it like amp decodes it. It actually sounds really good with amp. But yes, it uses very little cpu. Maybe less than dosamp.

      I had similar experiences. Yeah, I need to build it now. Have a few tracks that often have watery highs, just not crisp. Amp played them great. Maybe I will play your track after the family activities. Edit: Except access denied, lol. No worries.
