* ARMv5 optimized complex multiply function for libopus.Michael Giacomelli2013-01-21
| | | | | | | | | | | | | Speeds up decoding of 128k opus files by 1.2MHz on AMSv2. Rounding error is 1 bit due to KissFFT using a 15 bit shift instead of a 16 bit shift. Also, change an LDMIA in the armv4 code to LDM as the pointer should not increment.

* Add support for 16 bit 'half float' format PCM.Michael Giacomelli2012-11-22
| | | | | | | | | I'm not 100% sure that the rounding of denormals is correct. As compared to foobar2000, some samples are off by +1 LSB. However, since I can't output 24 bit PCM easily with rockbox, I'm not sure if this is due to a bug or just how rockbox rounds. In practice I don't think it matters so I'm just going to commit this for now. Change-Id: Ic0792fcb172e4369a5512d202121c2b918b36079

| | | | | | | | | | | | | | | | | 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.

* Fix corrupt when repeatidly playing very low bitrate WMA files.Michael Giacomelli2012-05-01
| | | | | | | | | | | | | | | | | | | 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.

* 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.
