MP3 resampling
I have some .mp3 files that I would like to resample to a lower bitrate
to take up less space. from what I have read, I should be able to do
this with lame with a cmdline of:
lame -abr56 infile.mp3 outfile.mp3
which would resample the output to an average bit rate of 56kbps, or:
lame -v -b56 infile.mp3 outfile.mp3
I tried using the second option, at 56, 64, and 128kbps. None of these
made much difference in the file size, however. I then tried :
lame -V6 infile.mp3 outfile.mp3
which cut the file size by about 20%.
When I tried using -abr the file size shrank by about 60%, but, I used
values of -abr56, -abr64, and -abr128. All three ouput files had the
same size and, according to mp3info, all were encoded at 64kbps.
What did I do wrong?
What is the best way to resample MP#s so that reasonable quality is
retained, while file size is noticeably reduced.?
