[Lame-dev] case study: multi-threaded LAME

[Alexander L. <Alexander@Leidinger.net>]

Hi,

a german company made a case study regarding multi-threaded LAME. Here  
is their result:

This is limited to 44kHz, 16 bit, joint-stereo, wav input, MP3 output  
(no other layers) and uses their async-programming framework, so it is  
not really something which we just can "copy".

But it seems that maybe libdispatch  
(http://libdispatch.macosforge.org/, respectively the Grand Central  
Dispatch API of Mac OS X) could allow a similar benefit. Obviously  
this API is available on OS X. It will be available soon on FreeBSD,  
and it will probably also not take too long until it can be used on  
Linux. Unfortunately I have no idea about a Windows port. If someone  
has a little bit of time and interest, he could maybe have a look if  
it is possible to integrate libdispatch without losing the ability to  
run without it (maybe with some not too complicated macros).

Bye,
Alexander.
