AUDIO PACKAGE SYMBOL
FrequencyModulation
creates a Sound object that is a frequency-modulated sinusoid, having carrier and modulating frequencies 
and 
, measured in hertz, peak deviation pd hertz, and a duration of dur seconds.
FrequencyModulation[fc, {{f1, pd1}, {f2, pd2}, ...}, dur, ModulationType->Cascade]
creates a cascade frequency-modulated sinusoid, where 
is the peak deviation associated with modulating frequency 
.
FrequencyModulation[fc, {{f1, pd1}, {f2, pd2}, ...}, dur, ModulationType->Parallel]
creates a parallel frequency-modulated sinusoid, where 
is the peak deviation associated with modulating frequency 
.
Details
- To use
, you first need to load the Audio Package using Needs["Audio`"]. - The following options can be given:
-
DisplayFunction Identity function to apply to sound before returning it ModulationType Standard the type of modulation to use 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 - The expression used by
is given by 
. - Cascade frequency modulation is a type of frequency modulation where the modulating frequency is itself modulated, thus cascading the modulation.
- In contrast to cascade frequency modulation, Parallel frequency modulation is a technique where the carrier frequency is modulated by two or more modulating frequencies that do not modulate each other.
