It's a riddle wrapped in a mystery inside an enigma. Judging by the somewhat odd structure of le_short() and be_short(), I think this keeps coming up over and over again. Even Apple's byte swapping macros fail under certain circumstances, and here's why: 1. Logical shifting must be used, not arithmetic (or else the high bit is wrong) 2.

Hi, I tried both the stable and beta versions of the speex source code download on Mac OS 10.4.9. I just do: ./configure make sudo make install Then I added libspeex.a from /usr/local/lib and the headers to my xcode project. My app compiles and I'm able to call all of the speex functions. I copied the example code from the website and tweaked it to include the first 10000 bytes of

I have an audio file compressed by JSpeex that I'm trying to decompress on the iPhone. I've been trying to work from the speexdec example in an attempt to port the core logic to ObjC. I have a class that does the decode and passes the result back to another class. (currently the other class is a unit test.) My other class is writing the converted output to disk. I compare the results of my

Hi all, Speex currently decides endianness at configure-time. This causes the ppc half of Mac universal binaries to have some endianness problems. Most notably, the header built by speex_packet_to_header() has incorrect byte-ordering. This Apple developer page describes the incantation that can be used to build universal binaries on Mac. It also highlights the configure-time versus compile-time

Hi, I got my hands on the LCA 2003 CD today and I tried to listen to it on my powerbook running Linux. Instead of getting speech, I got an earfull of noise! Attempting the same experiment on an i386 with the same CD produced understandable speech. It seems that the output routine in speexdec converts the output data to little endian short format, which is incorrect on the ppc architecture. The

I could not figure out how to use speexdec.exe 1.2.3 in piped mode in order to avoid the creation of the potentially large intermediate *.wav or *.pcm files. Any
