13 WildMidi_Init (const char *config_file, uint16_t rate, uint16_t
15 options)
16
18 Initializes libWildMidi in preparation for playback. This function only
19 needs to be called once by the program using libWildMidi.
20 config-file
22 The file that contains the instrument configuration for the
23 library.
24 rate The sound rate you want the the audio data output at. Rates
26 accepted by libWildMidi are 11025 - 65000.
27 options
29 The initial options to set for the library. see below.
30 WM_MO_LOG_VOLUME
32 By default the library uses linear volume levels typi‐
33 cally used in computer MIDI players. These can differ
34 somewhat to volume levels found on some midi hardware
35 which may use a volume curve based on decibels. This
36 option sets the volume levels to what you'd expect on
37 such devices.
38 WM_MO_ENHANCED_RESAMPLING
40 By default libWildMidi uses linear interpolation for the
41 resampling of the sound samples. Setting this option
42 enables the library to use a resampling method that
43 attempts to fill in the gaps giving richer sound.
44 WM_MO_REVERB
46 libWildMidi has an 8 reflection reverb engine. Use this
47 option to give more depth to the output.
48 WM_MO_WHOLETEMPO
50 Ignores the fractional or decimal part of a tempo set‐
51 ting. If you are having timing issues try
52 WM_MO_ROUNDTEMPO before trying this option. This option
53 added due to some software not supporting fractional tem‐
54 pos allowable in the MIDI specification.
55 WM_MO_ROUNDTEMPO
57 Rounds the fractional or decimal part of a tempo setting.
58 Try this option is you are having timing issues, if this
59 fails then try WM_MO_WHOLETEMPO. This option added due to
60 some software not supporting fractional tempos allowable
61 in the MIDI specification.
