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.

MidiSpectrumAnalyzer_Parse the midi file.

Parameters:

data

Raw data from the midi file.

Returns:

0 if no errors occured else number of the error.

MidiSpectrumAnalyzer_Reset the timers to 0.

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.

Array with values of the frequence groups.

Number of frequence groups.

Filter for the channels that the analyzer will monitoring. Good practice is to disable the drumps (channel 10).

Current time of the analyzer. If function Snd_MediaTimeGet is not available then this parrameter can be used for the MidiSpectrumAnalyzer_Update plus delta time (analyzer.MidiSpectrumAnalyzer_Update(analyzer.m_currentTime + s_game_frameDT)).
