Gregory Nutt 5e9a388ebd PCM decoder: Fix a logic error in a DEBUG assertion 2014-07-28 12:45:22 -06:00
Gregory Nutt 1da856cca9 PCM: Forget to increment pointers in one part of sub-sampling 2014-07-27 21:47:25 -06:00
Gregory Nutt ab26d97d74 PCM: Major simplification of the sub-sampling design. Now need no extra buffers because sub-sampling is done in place 2014-07-27 21:42:10 -06:00
Gregory Nutt 2efb594f50 PCM: remove partial sample buffer. Not needed 2014-07-27 21:00:19 -06:00
Gregory Nutt 38c095bd17 NxPlayer needs to set curbyte field to zero before enqueuing a buffer. Otherwise, it looks like beginning of the buffer has already been consumed 2014-07-27 19:49:01 -06:00

Gregory Nutt dba43a9c75 Audio: Get rid of the decoder->driver IOCTLs that I added a couple of commits back; Use existing configure method 2014-07-24 09:56:39 -06:00
Gregory Nutt ca779ece55 Audio: Add hooks for fast-forward and rewind needed by CMediaPlayer; add hooks for equalizer settings needed by the WM8904 2014-07-24 08:28:10 -06:00
Gregory Nutt 72133f5d95 Add ioctls so that PCM decoder can configure the driver bitrate, num channels, and sample width 2014-07-23 12:21:04 -06:00
Gregory Nutt 516b343666 Flesh out missing PCM decoder methods 2014-07-23 11:58:43 -06:00
Gregory Nutt cfa76b5278 Flesh out a few more PCM methods, still incomplete. Re-vision PCM structure definition 2014-07-22 19:23:05 -06:00
Gregory Nutt d7a9633dcd Rename pcm_decode.h to pcm.h since it will hold more than just decoding definitions. Fix some porting errors like idbg should auddbg, etc. Add wav file header and a few low-level wav utilities. 2014-07-22 15:54:56 -06:00
Gregory Nutt a4dcd690bb Add new framework for the PCM decoder. It is now a 'front end' for lower-level drivers like the WM8904 that performs the PCM decoding from end 2014-07-22 11:54:13 -06:00
Gregory Nutt b656602055 More changes to reduce complaints from CppCheck. Some latent bugs fixes, but probably some new typos introduced 2014-02-10 19:11:56 -06:00
Gregory Nutt 8b73558ad7 Moved audio/buffer.c to libc/audio/lib_buffer.c so that it can be shared betweent he OS and applications in a kernel build 2013-11-10 11:20:06 -06:00
