Index Selelctable Delay
Click here to return to the Basic DSP section.
Delays the input signal by the maximum number of samples selected on the list of spin text box using index select control input.
Input Pins
| Name | Format [int/dec/float] - [control/audio] | Function Description |
|---|---|---|
| Pin 0: control Data | int | Control input to select the delay |
| Pin 1: Audio Data | Float | Audio input |
Output Pins
| Name | Format [int/dec] - [control/audio] | Function Description |
|---|---|---|
| Pin 2: Audio Data | Float | Delayed audio signal |
GUI Controls
| GUI Control Name | Default Value | Range | Function Description |
|---|---|---|---|
| Max | 1 | 1 - 2500 | Variable delay can vary in between 0 to max delay value. There will be an option to display the delay in ms. |
| Cur_1 | 0 | 0 - Max | Samples delayed by this amount |
| Cur_2 | 0 | 0 - Max | Samples delayed by this amount |
Add-Growth Behaviour
Add algorithm is not supported.
Grow Algorithm is supported for Cur Delay control up to 16 and is not supported for input and output channels.
DSP Parameter Information
| Paramter | Calculation | Integer/Decimal/Float |
|---|---|---|
| Delay1 | Cur Spin text1 | Int |
| Delay2 | Cur Spin text1 | Int |
Implementation
This module shall implement a multiple delay line with the 'Delay Tap' signal as the actual delay value and delay tap applied to the input signal is selected by the external control index.
y(n) = { x(n-d(n)), if d(n)<Max
{ x(n-Max), if d(n)>=Max
Here,
y(n) is the output signal
y(n) is the input signal
d(n) is the Delay tap signal(delay value)
Max is the maximum delay value
Supported ICs
- ADSP-215xx
- ADSP-SC58x
