...d as 16 bits. I now got the vocoder compiling but when i compare the encoded output with a windows build, they don't match. Among the other problems i think that the char definition is one of the biggest players. I've seen in arch.h the following definitions: /* 2 on TI C5x DSP */ #define BYTES_PER_CHAR 2 #define BITS_PER_CHAR 16 #define LOG2_BITS_PER_CHAR 4 That makes me think the code is in someway ready to work on these kind of platforms. I don't see the above definition used anywhere in the code though. Does anybody know if CELT could work on platform with 16 bits char or if any attemp...

...fine. I don't know where that clicking noise is coming from. Any advice/comments/suggestions?

Hi everyone, I've recently done some major internal changes in Speex aimed at reducing RAM (by nearly a factor of 2!) and improving quality of the fixed-point. In doing so, I might have accidently broken a few things. I'd like to hear feedback on the current svn code to make sure I fix any regression before the next release. I'm already aware that --enable-vorbis-psy is broken and

...the c5x is essentially big endian My plan is to change int and unsigned int to int32_t and uint32_t where 32 bit ints are needed, such as in the stream header. I'm attaching a patch that updates bits.c to work with 16bit chars, renaming "byte" to "char" and using macros BYTES_PER_CHAR, BITS_PER_CHAR, and LOG2_BITS_PER_CHAR to keep the code portable between 8-bit chars and 16-bit chars. Other than compiling, I have not tested this code but I wanted a style check before going too far down this path. I hope that these changes or suitable reworking of them will be acceptable i...

...e the loopback application only uses speex_bits_write. Since this affects the Speex interface (just for these targets), I though I should ask for feedback before sending a patch. Does anybody care? Note that speex_bits_read_from is broken in other ways (the length checking is wrong for the if BYTES_PER_CHAR=2), so bits.c needs to be updated either way.

After searching the mailing list archive (I forgot to do that before posting, sorry!) I found the solutions: 1) The documentation has a mistake: The bit terminator is NOT set automatically! (I'm using the latest speex version!) It has to be set manually using speex_bits_insert_terminator(&bits); 2) speex_decoder_int() has to be called as long, as it returns -1. After that, all frames

...t's the case, then you're more than welcome to fix it. I think your judgement is much better than mine on this, so you can do it the way you like as long as the patch is clean enough. > Note that speex_bits_read_from is broken in other ways (the length checking > is wrong for the if BYTES_PER_CHAR=2), so bits.c needs to be updated either > way.
