how can a higher bitrate encoded mp3 be smaller than a lower one of the same length?

i'll explain: one version of a song is 4:17, encoded at 192 kbps, and is 6 mb. another version of the song is 4:18, encoded at 160 kbps, but is 7.2 mb. is this a cbr/vbr thing? a mistake in kazaa? or something else altogether?

don't trust what kazaa tells you 😛

variable bit rate

My guess would be VBR......and stop stealing music!!!!!!!!!!

we gotta be fair ... he never said if the music he was downloading was copyright. I mean it most certainly is .... but we just can't assume that.

ah. thanks!

Kazaa like Media Player doesn't seem to read VBR bitrates properly....many of my VBR160kbps files come up as things like 40kbps on kazaa and 350kbps on Media Player.

As people said, its VBR. Per second, any MP3 file will use either 160 or 192 for that one second of information in an MP3 file. THis will translate to varied file sizes, also how well the song will sound.

Or it just could be an incomplete song at 192Kbps. You'll hear 90% and then it cuts out. (<--nevermind, you had the times in there, so, I guess VBR too.)
