MP3 freeformat bitstream support

considering that uncompressed wav audio at 44100 16bit stereo is 1411kbps (1384kbps plus headers and such), 640kbps is technically compression, of 2.204:1 and just as lossless as the real lossless formats.

plus, hypothetically what happens if you have a 96khz 24bit (~2900-3000kbps) file and want to make an MP3 (or one of the lossless format) from that without resampling and bit-dithering (all contingent upon an encoder actually accepting that format), 320k just won't cut it, but 640kbps would be a ~4.531-4.687:1 compression

and I've used them all already also
Monkey's audio suports any sampling rate, and up to 24bit, but the compression is only ~2:1, no matter the WAV's format, you got 44100 16bit, you get ~700kbps, you got 96000 25bit, you get ~1500kbps
wavepack roughly same compression ratio unless using hybrid mode (making it lossy) and only up to 48khz 16bit
flac roughly same compression as wavepack and MAC unless using hybrid mode (making it lossy) and same format
I'll point you here for a comparison chart of the lossless formatsI'll point you here for a comparison chart of the lossless formats

so, where is the advantage of a 640kbps MP3 again? more actual compression over lossless formats

and there's also OGGVorbis, does nullsoft's decoder work with it's maximum bitrate of 512kbps? and that does cover more than just 2 channels
