you people are nuts (except for hi and lo).
1. Trader's Little Helper does not convert 24 bit files to 16 bit files. I don't think it has that capability, even if you wanted it to do it.
2. Foobar bit rates. It takes the total file size, and divides by the length of the song. That's it. a 16 bit / 44.1 kHz WAV file always shows up as 1411 kbps. take that same WAV file and convert it to FLAC, and foobar will show a different bit rate, most likely somewhere in the 700 - 915 kbps range, corresponding with the 50-65% relative size of FLAC files to WAV. But, as we all know, FLAC is lossless. but the overall file size has been compressed, so foobar displays a smaller bit rate. this is absolutely 100% how foobar works, for both 16 bit & 24 bit WAV and FLAC files.
