VU Meter
This agent takes audio in, calculates the RMS of the signal and outputs LED status values suitable for displaying as a bar-like VU meter.
Inputs
- Audio In : can take many audio inputs into the single port. The RMS is calculated as the average RMS of the combined signals (NB. it's not additive - should it be?)
Outputs
- light out : suitable for plumbing into kgroup/keyboard 'light input'
Parameters
- size : the number of keys to be used to display the VU meter : default 5
- signal threshold : (dB) signal present level/green. default : -40
- high threshold : (dB) signal high level/orange. default: -6
- clip threshold : (dB) signal clip level/red. default: -1
- clip hold : (seconds) seconds to hold the red light if the signal clips. default 5
Example Wiring
You will need to attach VU meter via a kgroup as shown
