Make Amiga music loop until fade out when changing scene. This is
based on watching a video of Future Wars Amiga walkthrough, not on
playing the Amiga version or reading its disassembly. But it does seem
that the music loops instead of just playing once.
Add support for dividing the playing rate of Paula and SoundFx audio
by integers other than 1. This is going to be used in the Cine engine
for dividing the playing rate of music in the Amiga version of Operation
Stealth by 2 to get it to sound right. Otherwise it sounds too high
pitched.
This is groundwork for fixing bug #11676.
The instrument names are a maximum of 22 characters in length but
were previously shortened to a maximum of 8 characters. At least in
Amiga versions of Operation Stealth some of the instrument names are
longer than 8 characters and failed to be loaded because of this.
Raising the limit from 8 to 22 characters fixes this.
Addresses bug #11676.
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.
As discussed on the mailing list we should use title capitalization
only for push buttons and tabs and use sentence capitalization for
everything else.
This is an attempt to fix a compilation error on some platforms.
The error message seems to indicate that log2 might be a define
on thos platforms.
Note that the log2 implementation in ModuleModXmS3m is not the binary
logarithm, and we cannot use Common::intLog2.
GCC did not warn about these, but surely it should be bitwise OR,
not logical OR, here as well. But I don't think I have any game that
uses MaxTrax (Amiga version of Legend of Kyrandia?), so I can't
really test this.
This fixes a Protracker module in the OS/2 version of
Hopkins FBI (bug #3612101). In row 0x30 of the first
pattern, the set channel offset effect in the fourth track
pushes the offset past the sample (repeat) length.
This is not error; the mixing function already handles this
case flawlessly. No assert() is necessary there.
A large part of cadavre.mod is broken. No new notes play, and only
the old background sounds remain. It's possible, perhaps even
probable, that the original MOD player didn't have this problem,
but all standalone players I've tried do, so I'm assuming it's the
file that's broken. We work around it by changing the length of
the song after it's been loaded to only include the good parts.
MKID_BE relied on unspecified behavior of the C++ compiler,
and as such was always a bit unsafe. The new MKTAG macro
is slightly less elegant, but does no longer depend on the
behavior of the compiler.
Inspired by FFmpeg, which has an almost identical macro.
