Drop the the mdct files from libwmapro since they are no longer needed.

Use codeclib's mdct in wmapro. Input coeffs to the transform needed to be scaled down first by (log2(frame_size) - 3). Increases decoding speed by 1.3MHz on PP5022 and saves ~32KB that were previously needed by the mdct tables. (FS#11511 by Buschel and myself)

More cleaning for libwmapro; use codeclib's bitstream functions and drop those from the libwmapro.

Initial cleanup for libwmapro.

Add WMA Pro to the main build. WMA Pro now plays on target and decodes in 151% realtime in a 320kbps sample on a sansa e200. Lots of cleanup still need to be done, and optimisations should start soon too.

Remove the floating point code from wmaprodec.c and change variable names accordingly.

Partial conversion of the wmapro decoder to fixed point arithmetic. Currently inverse quantization & rescaling,

imdct and windowing are all in fixed point.

Wrote apps/codecs/wmapro.c and modified libwmapro to make the codec work in the sim. Neither libwmapro nor wmapro.c have been added to the main build yet, codecs.make should be edited to compile both with rockbox.

2010-06-21T10:48:34+00:00

current status of the decoder :
- Plays and seeks in the sim
- Still in floating point
