Constructs new GLLibMidiSpectrumAnalyzer.
- Parameters:
-
bars Number of groups that the frequences will be analyzed in. Should be value between 1 and 128. maxValue Maximum value that is allowed for the frequence group. If the value become higher it will be clamped to the maxValue. velocityShift Left shift that will be used for shifting the velocity of the notes. Can be used if higher values are needed. millisShift Number of the milliseconds that passed from the last MidiSpectrumAnalyzer_Update is left shifted using this parameter and then subtract by the frequence level. If you use 64 groups you may want to left shift with one to have the same level as 128 groups. releaseDamping Value that will be damped from the frequence level if the note is released. Looks good with 0 but can be used in some combination with millisShift.
Member Function Documentation
| int MidiSpectrumAnalyzer_Parse | ( | byte[] | data | ) |
MidiSpectrumAnalyzer_Parse the midi file.
- Parameters:
-
data Raw data from the midi file.
- Returns:
- 0 if no errors occured else number of the error.
| void MidiSpectrumAnalyzer_Reset | ( | ) |
MidiSpectrumAnalyzer_Reset the timers to 0.
| int MidiSpectrumAnalyzer_Update | ( | long | timeMillis | ) |
MidiSpectrumAnalyzer_Update the timer to some position in the midi song.
- Parameters:
-
timeMillis Current media time. Should be GLLibPlayer.Snd_MediaTimeGet(...) if GLLib is used.
- Returns:
- 0 if no errors occured else number of the error.
