GXLame-t3. Changelog:- Slight tuning (some artifacts addressed)- Improved high frequency handling (helps stabilize cases of fading backbeat, etc)- Slight speedup
I noticed that gxlame doesn't like quiet samples like bruhns, bibilolo, Chariots of Fire (=sample02 from last mp3 test) etc.
Could you direct me to these sample clips?
Surely there's a central location for these killer samples?
PS: What version of GXLame did you use for the bitrate curve test?
LAME 3.99 alpha 6 (default and vbr-new)
Does this version have a different default VBR mode?
I wonder how it'll compare in listening tests.
current version is alpha 7 vbr-new behavior was tuned again...
GXLame-t4:- Reworked ath system- Lowpass raised (again) also at high bitrates (20.5Khz at V100)- Tuning- Changes in bitrate mapping as follows:Code: [Select]V0: 64kbps (resampling to 32Khz takes place at V5)V10: 79kbpsV20: 85kbpsV30: 96kbpsV40: 112kbpsV50: 128kbpsV60: 146kbpsV70: 162kbpsV80: 185kbpsV90: 224kbpsV100: 256kbpsI addressed some problem samples (some more than others, for various reasons), but in general I think you'll find perceptual quality has increased tremendously with this release. Special attention was given to "cleaning" up the sound and reducing ringing in certain situations. V20 (85kbps) is now perfectly usable on my player while on the go. (Of course, a deafeningly noisy bus commute with my rather strange collection of music blaring through cheap headphones doesn't vouch for everyone).This marks my first "alpha" release. Note that there is much left to be done. The new ath system has yet to mature and isn't yet used to its full potential. Also, abr (still) isn't tuned yet. Speed and stability have yet to be evaluated in the long haul. I recommend you use -f if things are moving too slowly for you, but speed tweaking isn't a priority now--the focus is on quality at very low bitrates (V10-V30 in particular). Let me know of any regressions, no matter how obvious or obscure. Cheers!

Thank You,Nice to see new version. It looks good at first sight. It really has less warbling but maybe at cost of some noise.Will get a try to it in these days.It is particularly interesting for me bitrate 96 kbps (V30) .Don't know if it is worth to compare to some of the LAME versions (settings) or other MP3 encoders which are tuned for low bitrates.
V100: 256kbpsV90: 224kbpsV80: 185kbpsV70: 162kbpsV60: 146kbpsV50: 128kbpsV40: 112kbpsV30: 96kbpsV20: 85kbpsV10: 75kbpsV0: 64kbps (actually 56kbps @ 32KHz; auto resampling to 32Khz takes place at V5 and below)
Just for the record (in case I'm not around for a test announcement like before), GXLame-t5.2 (or 5.3) can be used in any upcoming listening tests. In fact, I strongly encourage it and hereby enter it in any and all such tests.
Any volunteers? I probably can't since I work for one of the codec providers...
