# 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.
