granular¶
- class GranBase(grains, freq=10.0, jitter=0, random_offset=0, gain=1.0, offset=0.0)¶
Bases:
object- Parameters
grains (array(array)) – An array of audio buffers that will be used as a grain cloud
freq (float) – Frequency in Hz that grains will be fired at
jitter (float) – Ammount of jitter to apply to the grain firing frequency
random_offset (int) – An ammount of randomness that determines the sequence in which grains are fired
gain (float) – An ammount of gain to apply to the output
offset (float) – An ammount of offset to apply to the output
- Variables
freq_in_seconds (float) – The frequency represented as an ammount of time in seconds
current_grain (int) – The index of the currently playing grain
playing_grains (array) – An array of grain indecies that correspond to the grains currently playing
grain_positions (array(array)) – An array of indecies that correspond to the playback posistion of each grain
time (float) – The last value of time recieved
increment (int) – The number of grains to increment every time a grain is fired.
- fire_grain()¶
A function that fires a grain and increments pointers accordingly
- gain_to(gain)¶
- Parameters
gain (float) – A value to change the gain to
- get_pcm_value(time)¶
- Parameters
time (float) – The time in seconds of which the PCM value should be gotten for
- Returns
A PCM value for the granulator at a given time
- Return type
float
- get_sample(time)¶
- Parameters
time (float) – The time in seconds of which the sample should be gotten
- Returns
A PCM value for the granulator at a given time that has been adjusted with gain and offset
- Return type
float
- make_jitter()¶
A function that invokes an ammount of jitter on the grain firing frequency
