* Still need settings.h in dsp_misc.c for now for software volume.Michael Sevakis2012-04-30
| | | | Change-Id: I824e8f9935013f6e2a1db6ccd2db4bd406257057
* Make DSP's replaygain independent of global_settings.Michael Sevakis2012-04-30
| | | | | | | | | | Moves replaygain definitions to lib/rbcodec/dsp/dsp_misc.h. Intermediate functions in misc.c handle any adjustment and calling the rbcodec APIs.

* Fundamentally rewrite much of the audio DSP.Michael Sevakis2012-04-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Add a more correct absolute difference function to dsp-util.Michael Sevakis2012-04-26
| | | | | | | | | Differences between signed samples cover the entire unsigned 32-bit range. "abs" will think any difference exceeding INT32_MAX is negative which is not corrent.

* Add the warble test program.Sean Bartell2012-03-03
Warble uses Rockbox's codecs to play files with SDL or convert them to WAV or raw formats. It also prints metadata and supports some of the DSP effects. In the future, warble could be used to implement an automated test suite for codecs, metadata, and DSP.
