Hi Frank,
1. FFT filters are strictly speaking no filters (they are not a LTI system),
so they have some nasty properties, which are more or less audible. The
audibility depends on the steepness of the filter. So high passes should
never be made by FFT filters. Never ever.

Naoki IIRC, bug of winamp is also triggered by FhG encoded mp3 file.
This means that nitrane has more than one bug.
So, changing IXMAX_VAL to 8191 doesn't solve all problems.
I think we should investigate what FhG encoder does, and make lame do
what FhG does.

What about the proposal to design and discuss a well designed lame API now
without implementation? AFAICS this takes at least 3 months, if you want to
have a durable and neat API, Mark don't want to change the API until summer
2001. May be should use this time to design all the structures

Should we change IXMAX_VAL to 8191?
pros:
1. as Rob points out, less false syncwords in the bitstream.
(8206 is encoded as 0x1FFF).
2. LAME produced mp3's will no longer trigger Winamp bug.
cons:
1. Winamp may not bother to fix their decoder
2. Tiny loss in quality just to pander to
This is a good idea. Some comments (Frank: not all of these are serious:-)
I am serious :)
5. All developers should be required to take 200 hours of UML training
before working on any more code.
6. Learn more about CVS, especially about making your own branch.

Only keep valid frames from any MP3 files...
The problem is that I never released publicly the Win32 build/corrections...
And I have no time to do so :(

I was only wondering about the size of the wav's (not the binary contents).
As noted in a parallel reply from Mark, the discrepancy had something to do
with the VBR header being decoded into extraneous samples.
Thank you,

True, it was the -t encode switch.
By the way, isn't "lame -?" -t disable writing wav header when
using --decode a bit misleading about this?
Yes, that is a little misleading: "-t" option is listed twice,
since it disables wav headers when decoding, and disables
Xing headers when

Nullsoft sent me these .zip files, but I haven't tested them
yet. They are probably also available somewhere on www.winamp.com.
