- class Delay(nodes, len, fb, lenct=None)¶
Bases:
object- Parameters
nodes – An array of nodes that should be delayed
len (int) – The length of the delay line in samples
fb (float) – The ammount of feedback into the delay line
- Variables
buffer (array) – A buffer which contains audio data from the nodes
txrx (int) – A pointer to the read/write position in the buffer
- add_input(node)¶
- Parameters
node – Node to add to the delay line
- get_sample(time)¶
- Parameters
time (float) – The time in seconds of which the sample should be gotten
- Returns
A PCM value for the node at the given time
- Return type
float
- class MultiChannelDelay(nodes, len, fb)¶
Bases:
object- Parameters
nodes – An array of nodes that should be fed into the delay line
len (array(int)) – An array of lengths for each delay channel
fb (float) – Ammount of feedback into the delay line
- Variables
buffer (array) – An array of buffers of audio data in the delay line
txrx (array) – An array of read/write position values for the respective delay buffers
ch_num (int) – The current channel number which the buffer will be read from
- add_input(node)¶
- Parameters
node – Node to add to the delay line
- get_sample(time)¶
- Parameters
time (float) – The time in seconds of which the sample should be gotten

taps (array(int)) – An array of positions where the delay line should be tapped
- get_sample(time)¶
- Parameters
time (float) – The time in seconds of which the sample should be gotten
