Martin Schiff wrote: As I suspected, this story seems to be an urban legend (at least based on my tests). I used your file LoHorn.wav and recorded it digitally on my Sharp The first time this problem was discussed on the list, it was a completely different sound that caused it. I can't remember who discovered it but I can remember the sound - it was a bassy percussive type sound that sounded very synthesized, and I just thought that the synthetic nature of the sound was what caused it, ie. a strange waveform that the psychoacoustic model couldn't handle somehow. When the French Horn recording problem was then discovered, it eliminated that possibility because it was directly from a microphone. I'd also like to add that I didn't discover the problem, but followed it up with a second test when the original French Horn player (who's name I also don't remember) discovered it. I was able to reproduce the noise using my cousin's 722, using a digital link from a SB Live. I guess there's a possibility that not all units are affected - there may have been a bad batch of ATRAC chips that found their way into production. Intel seem to be able to do it all the time, why not Sharp? -cb - To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]

It happened the first time that sound sample was recorded when I tested it. No need for looping or anything, just record it from start to finish. I guess another factor that must be considered is whether the PC is playing the file at exactly the right speed. If the speed is wrong the pitch will change and the problem may not show up. -cb - To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]

I used your file LoHorn.wav and recorded it digitally on my Sharp MD-R2, then digitally on my Sharp 702, and finally analog through the line in on my Sharp 702. There was absolutely no distortion whatsoever in the recording. All the wave forms are perfectly normal and the copies sound just like the original (hiss and all). I would be happy to provide the wav file to anyone that would like a copy of it. I suspect that the person who originally experienced this problem had a bad cable or some other mechanical/electronic problem. To perform this test properly you've got to make a loop out of the signal you're recording. The number of samples in the loop should be: (number of samples) module 512 == 511 (or 1) Then repeat the loop 512 times (or more). ATRAC's window size is 512 samples (11.6ms) and this 1 sample shift will cause ATRAC to window the signal with every possible alignment boundary.
