What are you writing at first 22,050hz at 16Bit or smaller? in stereo, you could only go about 6 hours and 40 minutes at that rate before you'd fill a fat 32 disk with 2 gigabytes. 24K mp3s don't really sound that good, the smallest I do is 32K or 32K at the lowest vbr rating of the encoder engine I use, can't spell frahnhoffer but I tried, but, again, on the BP 24K mp3s I guess are ok. One mp3 at that length would be a little unwieldy to me, but that is just individual preference, and the bp does keep track of where you're reading in any case. What is a *.pca file? I am going to give GoldWave a look to see how they use noise reduction or how their native noise reduction works, it's worth the$50 because of the support to keyboards the program continues to have as well. Bruce, you're a good promulgator of the program, :) <grin>
