#include <revolution/axart.h>void AXARTInitLfo(AXART_LFO *lfo, f32 *samples, u32 length, f32 delta);| lfo | Pointer to AXART_LFO to initialize. |
| samples | Pointer to first sample of LFO shape. |
| length | Number of samples in the LFO shape. |
| delta | Delta per audio frame delta = Hz * (length / 200) |
The AXART library provides the following LFO shapes for use:
| Shape | *Samples | Length |
| Sine | AXARTSine | AXART_SINE_SAMPLES |
| Square | AXARTSquare | AXART_SQUARE_SAMPLES |
| Saw | AXARTSaw | AXART_SAW_SAMPLES |
| Reverse Saw | AXARTReverseSaw | AXART_REVERSESAW_SAMPLES |
| Triangle | AXARTTriangle | AXART_TRIANGLE_SAMPLES |
| Noise | AXARTNoise | AXART_NOISE_SAMPLES |
None.
AXARTInitLfo() initializes an AXART_LFO for use with articulators that contains an LFO for modulation.
