Hello, speexers. I'm new to the list and new to audio compression. I've been asked to look into creating a digital archive of 20-minute speeches (sermons) and speex seems to be what I need. My experience is in image compression; I shepherded gzip, deflate, zlib, and png through the IETF process, put &qu...

...this will be followed by a bit of wideband information that starts with a bit set to 1 (narrowband starts with a bit set to 0). Have a look at what the Speex decoder does. You may actually want to have similar code in a "null decoder".

Hi all Speexers, I've done some optimization to current SVN fixed-point on ARM9E platform. If the RVDS simulator gives the MCPS(Million Cycle Per Second) value A, then actual MCPS on real CPU will be around 2*A. I don't know what cause the big gap between the simulator and real CPU. What do you think...

Dear Speexers :-) I am trying to change the frame size from 20 ms to 10 ms, I did that by changing the value of the frame_size from 160 samples, to 80 samples in the sampleenc.c file. The number of frames increased as expected, but the size of the encoded stream of each frame remain the same! For example, if I...

Dear Sir/Miss: I'm very sorry to bother you,but I've found a bug in the Speex,Version 1.2beta1,and also I've have some questions. I'm deeply impressed by the work you have done in the coding and decoding of speech signal.But when using speex,I encoutered a bug,that is when in 32K mode,the window size is still 200 samples,but not 400 samples,the bug will bring the problem of

I have written a program which uses libspeex. Now i have tried to use the new version (1.2beta1), but when I try to compile with the new version of libspeex.lib and new h files, with Visual Studio .NET 2003, I get this error: fatal error LNK1262: link failed due to mismatched versions of 'C:\Programmi\Microsoft Visual Studio .NET 2003\Vc7\bin\c2.dll' and LINK.EXE Could someone help?
