| | | | | | | | | | | Since gcc 4.4 the MIPS port no longer recognizes the "h" asm constraint. It was necessary to remove this constraint in order to avoid generating unpredictable code sequences. We can achieve the same effect using 128-bit types. See also:GCC 4.4 release notes at http://gcc.gnu.org/gcc-4.4/ Change-Id: I713cdf57cde1a989ad960aa441ab1ccf51f1cdc6
* New crossfeed algorithm for Rockbox: "Meier" crossfeedBertrik Sikken2012-05-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Emulates the basic "Meier" crossfeed (2 capacitors, 3 resistors) as discussed in http://www.meier-audio.homepage.t-online.de/passivefilter.htm This crossfeed blends a bit of low-pass filtered L signal into the R signal (and vice versa) while adding about 300 us delay to the crossfed-signal. A difference with the crossfeed already present in rockbox, is that this algorithm keeps the total spectrum flat (the one currently in rockbox accentuates low-frequency signals, making it sound a bit muffled). This implementation is quite lightweight, just 3 multiplies per left-right pair of samples. Has a default C implementation and optimized assembly versions for ARM and Coldfire. The crossfeed effect is quite subtle and is noticeable mostly one albums that have very strong left-right separation (e.g. one instrument only on the left, another only on the right). In the user interface, the new crossfeed option appears as "Meier" and is not configureable. The existing crossfeed is renamed to "Custom" as it allows itself to be customised. There is no entry for the user manual yet. Change-Id: Iaa100616fe0fcd7e16f08cdb9a7f41501973eee1

* Expand the range of the inverse quant table in WMA Pro.Michael Giacomelli2012-05-20
| | | | | | | | | Several of the problem samples on the tracker use values outside this range. Trying the larger table doesn't quite seem to fix things, but its only a small amount of additional memory and looking at ffmpeg, I think the larger table is correct.

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