| * Fix audio outputMashiat Sarker Shakkhar2012-01-03
| | | | | | | | | | | | | | | | | | | | Up until now, the decoder didn't output anything in the data buffer. This fixes all the issues related to sample format, removes leftover code and actually outputs some audio to data buffer. With this, the only sample we have can be played. Seeking is still broken though.
| * Suppress dumping of residues bufferMashiat Sarker Shakkhar2012-01-03
| |
| * Use quantizer value read from bitstreamMashiat Sarker Shakkhar2012-01-01
| | | | | | | | | | | | Currently the code initializes quantizer even before reading it from bitstream and uses that to dequantize samples.

| * Use correct value for rangeMashiat Sarker Shakkhar2011-12-02
| | | | | | | | | | | | The current range value causes an underflow when negated and pushes anything less than zero to the minimum.
| * Fix some int / int16_t / int32_t confusionMashiat Sarker Shakkhar2011-12-02
| | | | | | | | | | For now force everything to int16_t, except for variables used as index

| | | | | | | | | | If everything works fine for 16-bit streams, the current code could be extended to do 24-bit.
| * Init s->cdlms[][].recent to order - 1Mashiat Sarker Shakkhar2011-11-30
| | | | | | | | | | | | Not sure if this is correct. But looks like it was giving us off-by-one's when used to index buffers.

| | | | | | | | (Resolves some conflicts)
| * Fix some int vs. int16_t confusionMashiat Sarker Shakkhar2011-11-30
| | | | | | | | | | Size should be determined from bits per sample. The current code only accepts 16-bit streams.
