Just a quick question, but what is the difference between constant and variable bitrate?
Constant (as the name suggests) uses a fixed rate at which to encode the song. Variable (as its name suggests) uses a variable rate to encode the song, more bits for more complex parts, less for less complex.
An acoustic guitar on its own wouldn't need a lot of bits, whereas a full blown orchestra at full tilt with everything going on would need more to capture each sound adequately.
Personally, I find CBR to soud sufficiently better than VBR, that I use it exclusively. After that, LAME is a touch better than other MP3 codecs.
as above, and VBR should be less batt intensive, since player works less for "simple" period of songs. And you save space
Actually, apparently VBR songs eat the battery more since there's more processing needing done on playback.
Sounds plausible since the processor is constantly changing the decoding rate whereas the CBR is a set value from start to finish.
