I'd like to let you know that I just released Speex 1.0-beta2:
"This second beta release brings many, many optimizations to the encoder and decoder. In some cases, the speedup is on the order of 50% to 100%. As part of the optimizations, some sections of Speex have been written in assembly with SSE instructions which can be enabled with the _USE_SSE flag when compiling with GCC. Finally, the code has received a major cleanup." Also the web site has been re-designed: http://www.speex.org/ |

Does the new speex encoder / decoder support high quality wav files for input or does it only take mono wav files? If it only takes mono wav files, can someone please tell me the best, quickest, simplest way to get a wav file to mono wav using a command line program, if any are available!

If you are a win32 user, you could use speexdrop which will do the downmixing (to mono) and the resampling for you.

Is it only me or it happens to everyone?
When I try to use speexdrop with a big audio file (1 hour lecture recording in 8khz, 16bit PCM) speexdrop increases in size and then almost kills the whole system. So after a few minutes speexdrop takes 700Mb of virtual memory. However if I use speexenc.exe, then everything is ok and very fast, total memory taken is only a few kb. May be it is possible to create speexdrop similar to LameDrop, where an external encoder is used? -------------------- My endian is bigger than yours.

Sounds like I have a memory leak problem. I'll look into it. Thanks for the notification.

It was indeed a memory leak. Problem fixed and new sources and exe, V0.0.3, uploaded to Mirror 1, below.
