search for: int16_t

Hi! I've spent the last few nights digging into the Vorbis source and working to implement a vorbis_synthesis_pcmout_int() function that kicks out interleaved int16_t pcm data. I think its important to have this function available to make the job for people using the codec a little easier. This function abstracts out the conversion to int16_t and removes the extra overhead of moving the pcm data over the processors data bus just to do the int16_t conversion aft...

LLVM's typedefs for int32_t etc. under MSVC (in Support/DataTypes.h) conflict with those used by other third-party libraries. Instead of these: #ifdef _MSC_VER typedef __int64 int64_t; typedef unsigned __int64 uint64_t; typedef signed int int32_t; typedef unsigned int uint32_t; typedef short int16_t; typedef unsigned short uint16_t; typedef signed char int8_t; typedef unsigned char uint8_t; typedef signed int ssize_t; #endif it would be preferable to use these: typedef __int8 int8_t; typedef __int16 int16_t; typedef __int32 int32_t; typedef __int64 int64_t; typedef unsigned __int8 uint8_t; t...

...tic unless you can just commit to one specific value of vscale. Also, I had a question about your table. Based on your description of how LMUL works, I’d expect that LMUL == vscale, and that each column in your table would be the same: int64_t | vscale x 1 x i64 int32_t | vscale x 2 x i32 int16_t | vscale x 4 x i16 int8_t | vscale x 8 x i8 … which is basically equivalent to: int64_t | LMUL x 1 x i64 int32_t | LMUL x 2 x i32 int16_t | LMUL x 4 x i16 int8_t | LMUL x 8 x i8 … is this not the case?

From: Jyri Sarha <jsarha at ti.com> I optimized Speex resampler for NEON capable ARM CPUs. The first patch should speed up resampling on any platform that can spare the increased memory usage. It would be nice to have these merged to the master branch. Please let me know if there is anything I can do to help the the merge. The patches have been rebased on top of master branch in
