- 2000-07-14 Erik de Castro Lopo <erikd@zip.com.au>
- * g72x.c
- Modified g72x_init_state () to fit in with the new structure of the code.
- Implemented g72x_encode_block () and g72x_decode_block ().
- 2000-07-12 Erik de Castro Lopo <erikd@zip.com.au>
- * g72x.h
- Moved nearly all definitions and function prototypes from this file have been
- moved to private.h.
- Added an enum defining the 4 different G72x ADPCM codecs.
- Added new function prototypes to define a cleaner interface to the encoder
- and decoder. This new interface also allows samples to be processed in blocks
- rather than on a sample by sample basis like the original code.
-
- * private.h
- Added prototypes moved from g72x.h.
- Changed struct g72x_state to a typedef struct { .. } G72x_PRIVATE.
- Added fields to G72x_PRIVATE required for working on blocks of samples.
- 2000-06-07 Erik de Castro Lopo <erikd@zip.com.au>
- * g72x.c
- Fixed all compiler warnings.
- Removed functions tandem_adjust() which is not required by libsndfile.
-
- * g721.c
- Fixed all compiler warnings.
- Removed functions tandem_adjust_alaw() and tandem_adjust_ulaw () which are not
- required by libsndfile.
- Removed second parameter to g721_encoder () which is not required.
- * g72x.h
- Removed in_coding and out_coding parameters from all functions. These allowed
- g72x encoding/decoding to/from A-law or u-law and are not required by libsndfile.
- Removed unneeded defines for A-law, u-law and linear encoding.
- * g723_16.c
- Removed second parameter (in_coding) for g723_16_encoder().
- Removed second parameter (out_coding) for g723_16_decoder().
-
