VBR V0 Bitrates close to 300 kbps
Reply #8 – 2012-07-05 21:47:05
I've posted the results of encoding a variety of music at different -V quality levels in a couple of other threads. Most end up in the 220 to 260 kbps average bitrate range, but I did see several over 290 kbps. Overall, LAME 3.99 increased the average bitrate of -V0 encoding compared to 3.98 to the point where you almost have to wonder if something is broken.http://www.hydrogenaudio.org/forums/index....st&p=796662 Here's a track that jumped from 253 kbps in LAME 3.98.4 to 299 kbps in LAME 3.99.5:M:\_Test-MP3>metamp3 --info "Ottmar Liebert - August Moon-V0-rw-3.98.4.mp3" metamp3 v0.91 - Copyright © 2006 by Tycho File: Ottmar Liebert - August Moon-V0-rw-3.98.4.mp3 Type : mpeg 1 layer III Mode : joint stereo Frequency : 44100 Hz Frames : 9671 Length : 00:04:12 Max.
