   2
   3         * g72x.c
   4         Added {} in function update () to prevent 'ambiguous else' warning messages.
   5
   6 2000-07-14  Erik de Castro Lopo  <erikd@mega-nerd.com>
   7
   8         * g72x.c
   9         Modified g72x_init_state () to fit in with the new structure of the code.
  10         Implemented g72x_encode_block () and g72x_decode_block ().
  11
  12 2000-07-12  Erik de Castro Lopo  <erikd@mega-nerd.com>
  13
  14     * g72x.h
  15     Moved nearly all definitions and function prototypes from this file have been
  16     moved to private.h.
  17     Added an enum defining the 4 different G72x ADPCM codecs.
  18     Added new function prototypes to define a cleaner interface to the encoder
  19     and decoder. This new interface also allows samples to be processed in blocks
  20     rather than on a sample by sample basis like the original code.
  21
  22     * private.h
  23     Added prototypes moved from g72x.h.
  24     Changed struct g72x_state to a typedef struct { .. } G72x_PRIVATE.
  25     Added fields to G72x_PRIVATE required for working on blocks of samples.
  26
  27 2000-06-07  Erik de Castro Lopo  <erikd@mega-nerd.com>
  28
  29     * g72x.c
  30     Fixed all compiler warnings.
  31     Removed functions tandem_adjust() which is not required by libsndfile.
  32
  33     * g721.c
  34     Fixed all compiler warnings.
  35     Removed functions tandem_adjust_alaw() and tandem_adjust_ulaw () which are not
  36     required by libsndfile.
  37     Removed second parameter to g721_encoder () which is not required.
  38
  39     * g72x.h
  40     Removed in_coding and out_coding parameters from all functions. These allowed
  41     g72x encoding/decoding to/from A-law or u-law and are not required by libsndfile.
  42     Removed unneeded defines for A-law, u-law and linear encoding.
  43
  44     * g723_16.c
  45     Removed second parameter (in_coding) for g723_16_encoder().
  46     Removed second parameter (out_coding) for g723_16_decoder().
  47
  48     * private.h
  49     New file containing prototypes and tyepdefs private to G72x code.
