* 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

* 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.

* Revise the PCM callback system after adding multichannel audio.Michael Sevakis2012-03-03
| | | | | | | | | | | | | | | | | | Additional status callback is added to pcm_play/rec_data instead of using a special function to set it. Status includes DMA error reporting to the status callback. Playback and recording callback become more alike except playback uses "const void **addr" (because the data should not be altered) and recording uses "void **addr". "const" is put in place throughout where appropriate. Most changes are fairly trivial. One that should be checked in particular because it isn't so much is telechips, if anyone cares to bother. PP5002 is not so trivial either but that tested as working.

* Initial commit of the Samsung YP-R0 port.Thomas Martitz2011-12-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This port is a hybrid native/RaaA port. It runs on a embedded linux system, but is the only application. It therefore can implement lots of stuff that native targets also implement, while leveraging the underlying linux kernel. The port is quite advanced. User interface, audio playback, plugins work mostly fine. Missing is e.g. power mangement and USB (see SamsungYPR0 wiki page). Included in utils/ypr0tools are scripts and programs required to generate a patched firmware. The patched firmware has the rootfs modified to load Rockbox. It includes a early/safe USB mode. This port needs a new toolchain, one that includes glibc headers and libraries. rockboxdev.sh can generate it, but e.g. codesourcey and distro packages may also work. Most of the initial effort is done by Lorenzo Miori and others (on ABI), including reverse engineering and patching of the original firmware, initial drivers, and more. Big thanks to you.

* GSoC/Buflib: Enable compaction in buflib.Thomas Martitz2011-08-30
| | | | | | | | | | | | | | | | | | | This enables the ability to allocate (and free) memory dynamically without fragmentation, through compaction. This means allocations can move and fragmentation be reduced. Most changes are preparing Rockbox for this, which many times means adding a move callback which can temporarily disable movement when the corresponding code is in a critical section. For now, the audio buffer allocation has a central role, because it's the one having allocated most. This buffer is able to shrink itself, for which it needs to stop playback for a very short moment. For this, audio_buffer_available() returns the size of the audio buffer which can possibly be used by other allocations because the audio buffer can shrink. lastfm scrobbling and timestretch can now be toggled at runtime without requiring a reboot. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30381 a1c6a512-1295-4272-9138-f99709370657

* Anti-Aliased Fonts support.Thomas Martitz2011-03-05
| | | | | | | | | | | | | This enables Rockbox to render anti-aliased fonts using an alpha blending method. The input font bitmaps are 4bit, i.e. 4x larger, but the metadata size stays the same. A tool, convttf, for converting ttf fonts directly to the Rockbox fnt format is provided. It has a useful help output, but the parameter that works best is -c1 or -c2 (2 for larger font sizes).
