high_pass_filter(source) Detrended version of the data by High Pass Filtering with a 40 Period cutoff
Parameters:
source: float, data source.
Returns: float.
transformed_dft(source, start_frequency, end_frequency) DFT by John Elhers.
Parameters:
source: float, data source.
start_frequency: int, lower bound of the frequency window, must be a positive number >= 0, window must be less than or 30.
end_frequency: int, upper bound of the frequency window, must be a positive number >= 0, window must be less than or 30.
Returns: tuple with float, float array.
db_to_rgb(db, transparency) converts the frequency decibels to rgb.
Parameters:
db: float, decibels value.
transparency: float, transparency value.
Returns: color.

版本注释:
v2 removed the upper limit for the function, corrected a typo in the code, thanks to Al-M for spotting it :)
版本注释:
v3 - another typo bytes the dust.. tump tump tump oO", nicely spoted by Al-M :)
版本注释:
v4 fixed the preview chart..
