Just thought I'd note that MPEG 2.5 is more or less broken at lower bitrates,
and that the filters seem screwy at low frequencies...
Try the following: (preferably with a 8kHz sample)
"LAME --resample 8 -b 8 <input> <output>" (MPEG2.5)
-> Notice how everything is garbled.
"LAME --resample 16 -b 8 <input> <output>" (MPEG2)
-> Notice how this sounds just fine compared to the previous.
Now, find a 8kHz sample somewhere and try this:
"LAME -b 8 <input> <output>" (Resamples to 16kHz (fix it when 2.5 works))
-> Notice how soft the output sounds.
"LAME -k -b 8 <input> <output>"
-> Notice the vast difference.
