2012-05-28New crossfeed algorithm for Rockbox: "Meier" crossfeedBertrik Sikken
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

2012-05-08Fix fat test program not compiling (FS#12646).Marcin Bukat
This changes the way creat() is wrapped around in native builds so more experienced devs should look at it. This patch forces to compile fat test in 32bit mode. Building natively on x86-64 works just fine but our fat code apparently can't deal with 64bit pointers/ints correctly.

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.

2012-01-03Rework powermgmt to enable code re-use on appliation and sims.Thomas Martitz
* Introduce CONFIG_BATTERY_MEASURE define, to allow targets (application) to break powermgmt.c's assumption about the ability to read battery voltage. There's now additionally percentage (android) and remaining time measure (maemo). No measure at all also works (sdl app). If voltage can't be measured, then battery_level() is king and it'll be used for power_history and runtime estimation. * Implement target's API in the simulator, i.e. _battery_voltage(), so it doesn't need to implement it's own powermgmt.c and other stubs. Now the sim behaves much more like a native target, although it still changes the simulated battery voltage quickly, * Other changes include include renaming battery_adc_voltage() to _battery_voltage(), for consistency with the new target functions and making some of the apps code aware that voltage and runtime estimation is not always available. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@31548 a1c6a512-1295-4272-9138-f99709370657

2011-08-30GSoC/Buflib: Enable compaction in buflib.Thomas Martitz
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
2011-08-14GSoC/Buflib: Replace all direct accesses to audiobuf with buffer API functions.Thomas Martitz
Namely, introduce buffer_get_buffer() and buffer_release_buffer(). buffer_get_buffer() aquires all available and grabs a lock, attempting to call buffer_alloc() or buffer_get_buffer() while this lock is locked will cause a panicf() (doesn't actually happen, but is for debugging purpose). buffer_release_buffer() unlocks that lock and can additionally increment the audiobuf buffer to make an allocation. Pass 0 to only unlock if buffer was used temporarily only. buffer_available() is a replacement function to query audiobuflen, i.e. what's left in the buffer. Buffer init is moved up in the init chain and handles ipodvideo64mb internally. Further changes happened to mp3data.c and talk.c as to not call the above API functions, but get the buffer from callers. The caller is the audio system which has the buffer lock while mp3data.c and talk mess with the buffer. mpeg.c now implements some buffer related functions of playback.h, especially audio_get_buffer(), allowing to reduce #ifdef hell a tiny bit. audiobuf and audiobufend are local to buffer.c now. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@30308 a1c6a512-1295-4272-9138-f99709370657
