makes life a bit more convenient for some MSVC users (or at least for me)

My commit 0e734722 causes lockups in SCUMM (sometimes) and SCI (very often). I didn't like the way I had fixed this before, but in the end I now had to do it in a similar way.

Timers should be reset only the first time the enable flag is sent. This also requires some updates to drivers which didn't send these flags accurately.

- Increase internal sample rate to dividers of the actual chip clocks and fix other related things. This seems to improve certain sfx/noise generator like sounds. The performance still seems to be okay.
- Fix feedback glitch that caused some noise with certain instrument patches when playing short notes.
- Fix squarewave sound glitch (mute channels when volume is zero; this could also cause unnecessary noise).
- Some cleanup.

The previous fix did not work as the forbidden exception had no effect
since scummsys.h and thus forbidden.h had already been included prior
to the fluidsynth header being included. This also meant that undefining
the exception define after the header would have had no effect anyway.
This new solution was suggest by eriktorbjorn on bug #11278 and should
avoid the need to add an exception which would persist over the entire
source file.

(move mixer calls before mutex lock, since the mixer has a mutex of its own)

The OPL3LPT is like the OPL2LPT with an OPL3 chip. Add OPL3 support to
the existing OPL2LPT driver.
There is no auto-detection of OPL3 capability. The user is required to
explicitly select OPL3LPT as their OPL device.
Tested with Sam & Max Hit the Road.

- move mac, pc speaker and fm-towns ims sound drivers into separate directory
(AdLib and MT32/GM drivers are still too entangled with common code to be moved so easily, especially MT32/GM. It would require lots of changes to the common code and possibly to all engines using the MidiDriver class. So I leave that for now.)

Paula low-pass filtering, as implemented by UAE.
The Amiga has two filtering circuits: a static RC filter
(only) on the A500, and an LED filter that can be enabled
or disabled dynamically.
By default, the Paula now doesn't apply the static RC
filter, but allows for enabling the LED filter (with
setAudioFilter()).
NOTE: At the moment, this code still uses floating point
arithmetics! It also calls tan() three times per
instantiation.

Fixes warning C4245: signed/unsigned mismatch
(seems in line with other decoders)
|
|
Fixes warning C4530: C++ exception handler used, but unwind semantics are not enabled
by disabling exceptions in the STL since ScummVM doesn't support them
|

This is another warning of the use of memset to clear a non-trivial
structure / class. This can be removed since the structure is cleared by
the constructor which will be called by the "new" so clearing this again
is redundant.

(just to remove some analysis warnings)
|

(also add some sanity checks and make some more adjustments for SCI audio driver)
|
|
(This didn't come up with the targets supported until now, but it does come up with SCI PC-98 music)

sort and rename some methods and vars and move as much as possible from public to private section
|
|
Apart from some basic cleanup this commit reverts a somewhat unfortunate design decision I made. The Kyra/Hof/Lol PC-98 sound drivers shouldn't inherit from the emulator. This commit separates the driver from the emulator putting some common interface in between. This should allow easier implementation of other PC-98 sound drivers.

No need to explicitly set it to 1.0. (There may have been in an
earlier version, to avoid any possible rounding error. But if so,
that reason is long gone.)

The high-resolution videos play back at much lower volume than the
original ones. This adds hard-coded values for how much to amplify
each cutscene. It's all done by ear, and it does introduce some
clipping, but I think it should be acceptable.
Of course, it could also be a problem with the audio decoder, so
this may be the wrong approach entirely.

It also hads further support for playing AIFF files. However, the
Blorb files for Lurking Horror & Sherlock on the if-archive website
don't seem to be valid AIFF files, so sound doesn't play using them

(This is basically an unnecessary emulation of a hardware limitation. EOB II will try to load approximately 70 KByte of samples for the outro sequence, which would lead to some missing sounds with the 64 Kbyte limit).

This code comes from clone2727's now defunct (?) ac3 branch.

Because scumm_strdup(), unlike strdup(), allocates strings with
new, not malloc(). (CID 1395228, 1395233, 1395235, 1395236)

The function signature for these functions was changed from (char *) to
(const char *) in the v1.1.7 release, so compiling against
Fluidsynth v1.1.6 or earlier requires the copying of the strings to
prevent compilation errors such as "error: invalid conversion from
'const char*' to 'char*'".
Normally, we would break compatibility with older versions as platforms
should be using the latest Fluidsynth v1.X release of v1.1.11.
However, since this is trivial to fix and prevents breakage for legacy
platforms, am restoring the string duplication with scumm_strdup().
Apart from this, we should look at the Fluidsynth v2.X releases
currently in RC testing as the API is now changed for this.

As discussed on the mailing list we should use title capitalization
only for push buttons and tabs and use sentence capitalization for
everything else.
