Serious problems for LAME mp3 , similar issues with AAC.

Thank you for applauding 3.99.5y, but I'm afraid something has gone wrong.
3.99.5y restricts its functional extension to only -V0+.
Did you use 3.99.5x instead? However 3.99.5x -V5+ doesn't help (for me), it takes an additional --adbr_min 200 to make this sample transparent to me (didn't try lower --adbr_min values).

To me this is not a pre-echo issue but a sample where Lame's psy model isn't quite right, but this flaw is overcome here by original Lame's top quality settings. With 3.99.5y problems like these are tackled by the internal --adbr_min feature which always keeps audio data bitrate above a certain threshold.

Sorry, I'm late replying, hence the full quote.

That's weird. My -V 5+ version was encoded by lame-3.99.5y.zip from your thread about that Lame version, halb27.

The -V 5 version encoded by it was 132kbps, LAME3.99y reported encoder (short string can't display the extra .5)
The -V 5+ version had a load more 320 kbps frames, and came out at 189kbps without running mp3packer. I have attached the -V 5+ version to this post.

--edit: the above info from foobar2000 before I realised I still had the original command prompt open--

I'd assume it's doing something when I run -V 5+ as indicated in --help. Perhaps it's reverting to the behaviour of LAME3.99.5x? Dunno.

Here's a CODEBOX with the --help info and the two encodes I ran. As luck would have it I still have the same Command Prompt Console open so I followed up with a -V 0 and -V 0+ encode, to compare, and there are actually 5 encodes in the following order:

1) lame3.98.4r -V 5
2) lame3.99.5y -V 5+ (file attached to this post)
3) lame3.99.5y -V 5
4) lame3.99.5y -V 0
5) lame3.99.5y -V 0+

I note that the percentage of short blocks is the same in the different encodes including a 3.98.4r encode I didn't spend time ABXing, but the -V 0+ encode is encoded very differently from the -V 5+

Please feel free to download the -V5+ encode attached to this post and examine it or ABX it between 0.9 and 1.9 seconds, or whatever you choose.

LAME 32bits version 3.99.5y (http://lame.sf.net)

usage: lame3995y.exe [options] <infile> [outfile]

<infile> and/or <outfile> can be "-", which means stdin/stdout.

RECOMMENDED:
lame -V2 input.wav output.mp3

OPTIONS:
-b bitrate set the bitrate, default 128 kbps
-h higher quality, but a little slower. Recommended.
-f fast mode (lower quality)
-V n quality setting for VBR. default n=4
0=high quality,bigger files. 9=smaller files
-V n+ compared to -V n, -V n+ has a significantly reduced
amount of inaccurately encoded frames due to
lacking data space. Moreover, it doesn't allow
audio data bitrate to go too low
--preset type type must be "medium", "standard", "extreme", "insane",
or a value for an average desired bitrate and depending
on the value specified, appropriate quality settings will
be used.
"--preset help" gives more info on these

--priority type sets the process priority
0,1 = Low priority
2 = normal priority
3,4 = High priority

--help id3 ID3 tagging related options

That's weird. ...

You're right, and the weirdness is definitely on my side. Sorry for the confusion.
I'm a bit upset about the version I uploaded which definitely doesn't work the way I intended (though it seems to have its advantages) and is not identical with my development version.
I'll try to find out about the problem. Sorry again.

Anyway, your finding shows that making Lame more defensive makes sense also with lower settings than -V0+. Thanks for that. I'll go back to work.
