Finally I made it: HeadAC3he v0.23. Due to lack of time I haven't debugged it enough and implemented as much as I liked (esp the downmixer). Here are the goodies:

- added WAV input
- added mp2 and mp3 input by using a modified version of mpglib (input is scanned on start-up to enable frame
selectioning and to minimise events of crashing on corrupt streams)
- used latest sources form LAME and modified mpglib with a floating point interface
- added mp3 pre delay fix (tuned for 48kHz LAME mp3s)
- added internal downmixer (now only to 1ch or 2ch possible) with DS2 ("Surround 2") downmix capabilities
- DS2 downmix for ac3 input added (6ch input is decoded with selected DRC for output ch)
- improved booster and added more boost functions
- new input formats fully integrated (cutting possible, though not advised on mp3 input if bit reservoir is used)
- deleted "quick mode" option from mp2, as I found out I understood it wrongly after looking into the source again
- added "4ch" preset and made all three presets configurable by INI file
- some (drastic) internal changes and a bunch of fixes
- following settings are forced on update:
global gain to 0
downmix to surround 2
private flag for mp2/mp3 to 0

- global gain is used for wav/mp2/mp3 input in 1pass mode and input gains are used by downmixer (only if downmixing is done)



A lot of dlls have been updated as well.
I'll be offline till June, as I will travel far away...If you don't hear anything then it either means I died of plane crash or a tropical disease or I have better things to do. ;-)

Shit, I forgot:

I now use official lame (CVS) as it is based on john33 code. So you can use official, esp while I am away. ;)

BTW, if you don't get, what the pre delay fix (not really, rather a primitive work-around) for mp3s is about:
