This is an improvement to the current compressor which I have added
to my own Sansa Fuze V2 build. I am submitting here in case others
find it interesting.
Features added to the existing compressor:
Attack, Look-ahead, Sidechain Filtering.
Exponential attack and release characteristic response.
Benefits from adding missing features:
Attack:
Preserve perceived "brightness" of tone by letting onset transients
come through at a higher level than the rest of the compressed program
material.
Look-ahead:
With Attack comes clipping on the leading several cycles of a transient
onset. With look-ahead function, this can be pre-emptively mitigated with
a slower gain change (less distortion). Look-ahead limiting is implemented
to prevent clipping while keeping gain change ramp to an interval near 3ms
instead of instant attack.
The existing compressor implementation distorts the leading edge of a
transient by causing instant gain change, resulting in log() distortion.
This sounds "woofy" to me.
Exponential Attack/Release:
eMore natural sounding. On attack, this is a true straight line of 10dB per
attack interval. Release is a little different, however, sounds natural as
an analog compressor.
Sidechain Filtering:
Mild high-pass filter reduces response to low frequency onsets. For example,
a hard kick drum is less likely to make the whole of the program material
appear to fade in and out. Combined with a moderate attack time, such a
transient will ride through with minimal audible artifact.
Overall these changes make dynamic music sound more "open", more natural. The
goal of a compressor is to make dyanamic music sound louder without necessarily
sounding as though it has been compressed. I believe these changes come closer to this goal.
Enjoy. If not, I am enjoying it

As comment in code states:
"It is possible for our seek to land in the middle of audio
data that looks exactly like a frame header from a future
version of an encoder. When that happens, frame_sync() will
return false. But there is a remote possibility that it is
properly synced at such a "future-codec frame", so to make sure,
we wait to see several "unparseable" errors in a row before
bailing out."
Currently we wait for 10 "unparseable" errors. libFLAC waits for 20.
But I've got a valid flac+cue, wherein switching to certain track
gave me 24 "unparsaeable" errors. Therefore I increased
unparseable_count to 30.

Sync opus codec to upstream commit
02fed471a4568852d6618e041c4f2af0d7730ee2 (August 30 2013)
This brings in a lot of optimizations but also makes the diff
between our codec and the upstream much smaller as most of our
optimizations have been upstreamed or supeceded.
Speedups across the board for CELT mode files:
64kbps 128kbps
H300 9.82MHz 15.48MHz
c200 4.86MHz 9.63MHz
fuze v1 10.32MHz 15.92MHz
For the silk mode test file (16kbps) arm targets get a speedup
of about 2MHz while the H300 is 7.8MHz slower, likely because it's
now using the pseudostack more rather than the real stack which
is in iram. Patches to get around that are upcomming.

Instead of providing yet another memory allocator implementation
use tlsf and simply link tlsf library.
Another small improvement is to *grow* memory pool by grabbing
audiobuffer instead of just switching to use audiobuf exclusively.
Tested with simple lua 'memory eater' script.
This patch extends tlsf lib slightly. You can provide
void *get_new_area(size_t * size) function which will override
weak dummy implementation provided in lib itself. This allows to
automaticaly initialize memory pool as well as grow memory
pool if needed (for example grab audiobuffer when pluginbuffer
is exhaused).

Replaces the NATIVE_FREQUENCY constant with a configurable frequency.
The user may select 48000Hz if the hardware supports it. The default is
still 44100Hz and the minimum is 44100Hz. The setting is located in the
playback settings, under "Frequency".
"Frequency" was duplicated in english.lang for now to avoid having to
fix every .lang file for the moment and throwing everything out of sync
because of the new play_frequency feature in features.txt. The next
cleanup should combine it with the one included for recording and
generalize the ID label.
If the hardware doesn't support 48000Hz, no setting will be available.
On particular hardware where very high rates are practical and desireable,
the upper bound can be extended by patching.
The PCM mixer can be configured to play at the full hardware frequency
range. The DSP core can configure to the hardware minimum up to the
maximum playback setting (some buffers must be reserved according to
the maximum rate).
If only 44100Hz is supported or possible on a given target for playback,
using the DSP and mixer at other samperates is possible if the hardware
offers them.

Basically, just give it a good rewrite.
Software codec recording can be implemented in a more straightforward
and simple manner and made more robust through the better codec
control now available.
Encoded audio buffer uses a packed format instead of fixed-size
chunks and uses smaller data headers leading to more efficient usage.
The greatest benefit is with a VBR format like wavpack which needs
to request a maximum size but only actually ends up committing part
of that request.
No guard buffers are used for either PCM or encoded audio. PCM is
read into the codec's provided buffer and mono conversion done at
that time in the core if required. Any highly-specialized sample
conversion is still done within the codec itself, such as 32-bit
(wavpack) or interleaved mono (mp3).
There is no longer a separate filename array. All metadata goes
onto the main encoded audio buffer, eliminating any predermined
file limit on the buffer as well as not wasting the space for
unused path queue slots.
The core and codec interface is less awkward and a bit more sensible.
Some less useful interface features were removed. Threads are kept
on narrow code paths ie. the audio thread never calls encoding
functions and the codec thread never calls file functions as before.
Codecs no longer call file functions directly. Writes are buffered
in the core and data written to storage in larger chunks to speed up
flushing of data. In fact, codecs are no longer aware of the stream
being a file at all and have no access to the fd.
SPDIF frequency detection no longer requires a restart of recording
or plugging the source before entering the screen. It will poll
for changes and update when stopped or prerecording (which does
discard now-invalid prerecorded data).
I've seen to it that writing a proper header on full disk works
when the format makes it reasonably practical to do so. Other cases
may have incorrect data sizes but sample info will be in tact. File
left that way may play anyway.
mp3_enc.codec acquires the ability to write 'Info' headers with LAME
tags to make it gapless (bonus).

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.

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.

due to lack of user feedback the actual tags may change, hopefully not though.
The way it works is the skin specifies a rectangle and a viewport label. For each item in the list that is being displayed all viewports with the specified label are drawn. However, instead of the viewport x/y position being offset from the top left corner like normal they are offset from the rectangle position in the list (so think of them as child-viewports of the rectangle which moves).
Normally the rectangle will move down the screen to show a normal list, this can be changed to move across the screen in a grid pattern.
The UI viewport is used to bound the items (i.e %Vi() )
Scrolling is completly disabled in all items except the currently selected item.
This works well in combination with the %cs tag to show differently styled lists based on the current screen :)
New tags:
%LT - Get the current items text
%LI - Get the current items icon number
%Lc - Use as a conditional to determine if the current item is the selected item
%LB - BAR TAG to show the scroll bar, params/options like other bar types. It still needs a bit of work though. Use as a conditional to find out if the bar is actually needed
%Lb(viewport, width, height [,tile]) - specify the viewport label to draw for each item and the size of each item. if the last param is 'tile' it will form a grid instead of a list
example.sbs:
%?cs<%Lb(a,100,20)|>
%V(0,0,10,-,1)%Vf(aabbcc)

%pL for the left channel, %pR for the right channel... usable as a value, conditional or bar (exactly the same as %pv/%bl/etc)

As a conditional it scales its value to the number of options you give it (like volume)

We want simulators to simulate target code where possible, that includes memory constraints and memory allocation schemes. It also removed the sim's ability to show the theme's ram usage.
Use malloc only in application builds.

It caused the parser to not see that skin parsing failed and to enter an infinite loop.
And as a result it continued to endlessly malloc(). In normal build the skin buffer size limit made it end.

They now only parse the correct branch (so only the true branch, or only the false branch). This shuold allow you to load different images/backdrops with the same id's depending on the targets hardware.
Add a new %Tp - "touchscreen present?" tag to check if the target has a touchscreen

Don't crash when not enough params were given (i.e forgetting the filename)
Make the parser enforce the first 4 params as compulsary
Be more leniant and don't require the image filename if one isnt going to be loaded (no more need for the - as the 5th param)
Add an option "image" to specify the filename (otherwise the first option will be used if it isnt a recognised option).
e.g: %pv(0,0,100,10) or %pv(0,0,100,10, bar.bmp) or %pv(0,0,100,10, ..., image, bar.bmp)

The register prefix is always % for the architecture we use (elf),
hardcode it instead of confusing the preprocessor

%Fl now takes an optional 3rd param which is the number of glyphs to cache (default to 256). the smaller the number, the less ram will be used (i.e using 15 for a font which only shown numbers is a good idea)

It's used by both, plugins and codecs, and sh/hwcodec doesn't compile codecs
so it doesn't fit into sources.

<tag> is the tag to check against
<operator> is the comparisson to do, any one of... =, !=, >, >=, <, <= (when comparring against a string tag like %ia only = and != work, and it is done NOT case sensitive)
<operand> is either another tag, a number, or text.
[option count] is an optinal number to use for the few tags which scale to the amount of options when used as a conditional (i.e %?pv<a|b|c|d> would have 4 options)
example: %?if(%pv, >=, 0)<Warning.. volume clipping|coool...>
That says "If the value from %pv (volume) is greater than or equal to 0 then display the warning line, otherwise the cool line."
%?if(%ia, =, %Ia)<same artist> <= this artist and next artist are the same.
some tags might need a touch of tweaking to work better with this. experiment and have fun

* the bar orientation (horiz/vert) is now chosen based on the width and heigt values (or can be forced).
* the fill direction can now be inverted (fill right to left, or top to bottom is considered inverted)
* It can now draw a slider type bar instead of a fill type (or indeed a slider with a fill type)
To configure the new bar, any (or all) of the following params can be used after the bmp filename (order makes no difference either):
invert - cause the bar to fill in the inverted direction
vertical - draw a vertical bar (not needed if the height > width)
horizontal - draw a horizontal bar (this is obviously the default)
nofill - dont draw the filling bar (this still draws the outline, obviously pointless without the slider param)
slider - draw an image for the slider. The next param MUST be the label of the image to draw. No option to use a subimage here, so the whole image needs to be the image you want on the slider.
example: %pb(0,0,-,-,-,nofill, slider, slider_image, invert) - draw a boring horizontal progressbar which doesnt fill and only draws the image "slider_image" which moves right to left.
the slider type might need some tweaking. let us know how it goes

example: %Vp(1, %?it<%in -%it|%fn>) <- show the next tracks strating from the first next track and show info if it is avilable or the filename.
Basic cuesheet support here, and will load upcoming track tags from the database if you have load to ram enabled.

Also adds the possibility to specify a set of params which a tag can have (i.e a tag or a integer)
git-svn-id: svn://svn.rockbox.org/rockbox/trunk@27812 a1c6a512-1295-4272-9138-f99709370657
example:
%xl(I, __list_icons__, 0, 0)
%xd(I, %Li)
^ display the list icon at position 0,0 in that viewport. (you can of course %xd(Ia) if you really wanted also.)

It can now automatically load the correct subimage from a strip (assuming the strip is in the correct order) by giving a tag for the 2nd param.
example: %xd(F, %mp) which is equivilant to %?mp<%xd(Fa)|%xd(Fb)|%xd(Fc)|%xd(Fd)|%xd(Fe)>
You can also set the subimage offset.. i.e %xd(E, %mm, -1) which means "show nothing for the first value of %mm and use the bitmap strip for the remaining values"
if a tag+offset is <0 or greater than the number of subimages in a strip he image is cleared (I'm open to changing this if someone has a better idea)
cabbiev2.176x220x16.wps is an example of how to use this

- add similar trickery that is used for the libraries used by Rockbox Utility
to allow building as universal binary.
- don't overwrite CC, we need to set this from outside for building OS X 10.4
compatible binaries.
- extend Theme Editor project file to build 10.4 compatible binaries on OS X.
