Detailed Description

-

template<uint16_t NUM_BUFFER_SAMPLES, int8_t INTERP_TYPE = LINEAR>
-class AudioDelayFeedback< NUM_BUFFER_SAMPLES, INTERP_TYPE >

+

template<uint16_t NUM_BUFFER_SAMPLES, int8_t INTERP_TYPE = LINEAR, typename su = int8_t>
+class AudioDelayFeedback< NUM_BUFFER_SAMPLES, INTERP_TYPE, su >

Audio delay line with feedback for comb filter, flange, chorus and short echo effects.

Template Parameters
+
NUM_BUFFER_SAMPLESis the length of the delay buffer in samples, and should be a power of two. The maximum delay length which will fit in an atmega328 is half that of a plain AudioDelay object, in this case 256 cells, or about 15 milliseconds. AudioDelayFeedback uses int16_t sized cells to accomodate the higher amplitude of direct input to the delay as well as the feedback, without losing precision. Output is only the delay line signal. If you want to mix the delay with the input, do it in your sketch. AudioDelayFeedback uses more processing and memory than a plain AudioDelay, but allows for more dramatic effects with feedback.
INTERP_TYPEa choice of LINEAR (default) or ALLPASS interpolation. LINEAR is better for sweeping delay times, ALLPASS may be better for reverb-like effects.
suthe type of numbers to use for the signal in the delay. The default is int8_t, but int16_t could be useful. Larger types (int32_t) might produce overflows as of v2.0.2.
