Port List

0) Control

(Atom Input)

GUI to plugin communication

Designation:

  • Control-port

2) InL

(Audio Input)

Channel 1 input

4) InR

(Audio Input)

Channel 2 input

6) FFT Size

(Control Input)

Number of audio-samples to process. Large values increase accuracy as well as latency.

Port Properties:

  • Integer
  • Enumeration

Default: 2048.000000

Scale Points
256.0256
512.0512
1024.01024
2048.02048
4096.04096
8192.08192
12288.012288
16384.016384

7) N/Octave Bands

(Control Input)

Group data by frequency bands. This allows for 1/frequency (pink noise) signal level normalization. It also speeds up visualization for large FFT sizes and decreases CPU/GPU usage due to visualization.

Port Properties:

  • Toggle
  • Integer

Range
min0.000000
max1.000000
default1.000000

8) Screen Persistence

(Control Input)

Screen persistence (fade out speed). 0: no persistence, 100: permanent. Values above ~66 result in a permanent shadow.

Range
min0.000000
max100.000000
default50.000000
