INTRODUCTION
|
||||
============
|
||||
mp3encode is a package for encoding MPEG layer I, II and III audio
|
||||
files. This is the reference implementation so don't expect
|
||||
spectacular performance.
|
||||
|
||||
Driving encode is pretty simple although it may take some practice to
|
||||
work out an optimal compression rate. AIFF files are the only type of
|
||||
files that seem to work with this version so you may need to install a
|
||||
port like "sox" to convert your file types. I use the "nas" port to
|
||||
record and edit all of my audio files but so long as you have a valid
|
||||
AIFF file it shouldn't matter what you use.
|
||||
|
||||
Although the source code includes a decoder I have decided not to port
|
||||
it because we already have a couple of top class mpeg decoders in the
|
||||
ports collection.
|
||||
|
||||
HINTS & TIPS
|
||||
============
|
||||
Physcoacoustic model 2 is the only supported model in layer III
|
||||
encoding. A bit-rate of 128Kbps is adequate for most forms of music but
|
||||
you may need to turn down the compression to 160Kbps if the music is
|
||||
particularly atmospheric.
|
||||
|
||||
Vocal spoken recordings are best encoded using a 32Kbps bit-rate with
|
||||
layer II (layer III makes you sound like a Dalek under digital water)
|
||||
with a 32kHz sample rate in mono. Using this method I have managed to
|
||||
get about 5 minutes of AM Radio quality audio into around 1 MB.
|
||||
