2012-05-07rbcodec: abstract tdspeed buffer allocationNils Wallménius
Move code dealing with rockbox specific buflib allocations into a rockbox specific file and implement buffer allocation with malloc/free for warble/stand alone lib. Based on patch by Sean Bartell.

2012-05-03Add rbcodecplatform.h and rbcodecconfig.h.Sean Bartell
librbcodec users must provide these two files when the library is built. rbcodecconfig.h provides configuration #defines and basic types, and will be included by public librbcodec headers, so it must not conflict with the user's code. rbcodecplatform.h provides various OS functions, and will only be included by source files and private headers. This system is intended to provide maximum flexibility for use on embedded systems, where no operating system headers are included. Unix systems can just copy rbcodecconfig-example.h and rbcodecplatform-unix.h with minimal changes.

2012-05-01Fix corrupt when repeatidly playing very low bitrate WMA files.Michael Giacomelli
The LSP feature in WMA requires that the noise table values be doubled verses when it is not used. Unfortunately, the previous code would double the same values every time a LSP file was decoded without first resetting them to their original values. Change the code to check if the values are already doubled, and then double/halve them as needed. This is still a bit ugly, in the future consider using the built in rockbox dither instead of a lookup table. Fixes playback when skipping back and forth between low and high bitrate WMA.

2012-04-29Fundamentally rewrite much of the audio DSP.Michael Sevakis
Creates a standard buffer passing, local data passing and messaging system for processing stages. Stages can be moved to their own source files to reduce clutter and ease assimilation of new ones. dsp.c becomes dsp_core.c which supports an engine and framework for effects. Formats and change notifications are passed along with the buffer so that they arrive at the correct time at each stage in the chain regardless of the internal delays of a particular one. Removes restrictions on the number of samples that can be processed at a time and it pays attention to destination buffer size restrictions without having to limit input count, which also allows pcmbuf to remain fuller and safely set its own buffer limits as it sees fit. There is no longer a need to query input/output counts given a certain number of input samples; just give it the sizes of the source and destination buffers. Works in harmony with stages that are not deterministic in terms of sample input/output ratio (like both resamplers but most notably the timestretch). As a result it fixes quirks with timestretch hanging up with certain settings and it now operates properly throughout its full settings range.
