Audio Encoding

Like video encoding, several audio codecs are available to use. MP3 is easily the most popular, being the first to receive massive use for encoding personal collections. However WMA can provide higher quality at the same bitrates, and seems to encode faster. OGG is another solution, supported by the open-source community. It also boasts higher quality over MP3 at similar bitrates.

This test was performed by encoding a 45 minute WAV track ripped directly from a CD. dbPowerAMP was used, with the three codecs downloaded from their Codec Base. All tests were done in 192 kbps constant bitrate, single pass. Total encoding time in seconds was given:

More intriguing than the CPU results is the fact that OGG takes so long to encode a CD! I mean seriously, what would you rather sit through? 45 seconds in WMA, or 4 minutes on an OGG file?

MusicMatch Jukebox 7.1

Another Worldbench 5 test, this is a more robust encoding solution than dbPowerAMP. MP3 was used here:

Once again, the P4 simply spanks the Athlon64's in this encoding test. Like video encoding, the P4 simply is the better solution at this point.
