ListWaveform

ListWaveform[{{f₁, a₁}, {f₂, a₂}, ...}, freq, dur]
creates a Sound object with fundamental frequency of freq hertz, lasting for dur seconds, with a spectrum in which relative frequency f_i has relative amplitude a_i.

MORE INFORMATION

To use ListWaveform, you first need to load the Audio Package using Needs["Audio`"].

Relative frequencies f_i are measured relative to the fundamental frequency freq.

ListWaveform allows you to create a waveform with a specific spectrum.

The following options can be given:

DisplayFunction	Identity	function to apply to sound before returning it
PlayRange	All	range of sound amplitude levels to include
SampleDepth	8	number of bits used to encode sound amplitude
SampleRate	8192	sampling rate per second
