heavily customized version of DUMB (Dynamic Universal Music Bibliotheque).
It has been slightly modified by me:
* Added support for Ogg Vorbis-compressed samples in XM files ala FMOD.
* Removed excessive mallocs from the replay core.
* Rerolled the loops in resample.c. Unrolling them made the object file
~250k large while providing little benefit. Even at ~100k, I think it's
still larger than it ought to be, but I'll live with it for now.
Other than that, it's essentially the same thing you'd hear in foobar2000,
minus some subsong detection features. Release builds of the library look
like they might even be slightly faster than FMOD, which is a plus.
- Fixed: Timidity::font_add() did not release the file reader it created.
- Fixed: The SF2 loader did not free the sample headers in its destructor.

# Please edit this file to control the playback quality for 'dumbplay'. Note
|
|
# that this does not affect DUMB when you use it in your own programs; you
|
|
# need to borrow some code from the example program in order to get that to
|
|
# happen.
|
|
|
|
# dumb_resampling_quality can be 0 for aliasing, 1 for linear interpolation
|
|
# or 2 for cubic interpolation. See docs/dumb.txt for details on what these
|
|
# terms mean.
|
|
|
|
# dumb_it_max_to_mix is the maximum number of samples DUMB will render at a
|
|
# time. See docs/dumb.txt for a more detailed description.
|
|
|
|
# Increase buffer_size to combat stuttering.
|
|
|
|
# The music module will be rendered at the sampling frequency specified by
|
|
# sound_freq. This variable is also used by Allegro for initialising the
|
|
# sound hardware.
|
|
|
|
# buffer_size and sound_freq are passed directly to al_start_duh(). See this
|
|
# function's description in docs/dumb.txt for information about how to use
|
|
# these variables.
|
|
|
|
# You can ignore the quality variable. Allegro uses it when relaying the
|
|
# audio stream to the sound card. Only a masochist would set it lower than 2;
|
|
# if your computer is powerful enough to run DUMB, it is powerful enough to
|
|
# use this setting with Allegro.
|
|
|
|
# For best results, choose a value for sound_freq that your sound card can do
|
|
# exactly. See Allegro's docs, "Standard config variables", for details. If
|
|
# you do not choose an exact value, Allegro will round it to the nearest
|
|
# value it can do; then when DUMB plays the stream at a sampling frequency of
|
|
# sound_freq, Allegro will have to resample it. Allegro's 'quality = 2'
|
|
# setting is only comparable with DUMB's 'dumb_resampling_quality = 1'
|
|
# setting. Therefore, in order to appreciate DUMB's cubic resampler fully,
|
|
# you will need to make sure Allegro doesn't do any resampling, by choosing
|
|
# an exact value for sound_freq.
