TONE

TONE - sine/tone generator

Usage:

TONE a f p n sr

Inputs:

a	amplitude component
f	frequency component
p	phase component
n	number of components
sr	sampling rate

Outputs:

y	synthesized signal sample (number)

Function:

The TONE atom uses additive synthesis of sine waves to synthesize signal samples. Because the signal is synthesized sample by sample and all inputs are updated before each evaluation cycle, all parameters are variable (modulation!). The following input connections are possible:

harmonic tone with equal magnitudes:

with

Anumber	magnitude for all components
Fnumber	fundamental frequency of harmonic tone
Pnumber	starting phase for all components (default: P=0)
Nnumber	number of harmonics (default: N=1)

harmonic tone with different magnitudes:

with

Avector	component magnitudes
Fnumber	fundamental frequency of harmonic tone
Pnumber	starting phase for all components (default: P=0)
n	number of harmonics = length of vector A

tone with sinoid components:

with

Avector	component magnitudes
Fvector	fundamental frequency of harmonic tone
Pnumber/vector	starting phase of components (default: P=0)
n	number of harmonics = length of input vectors

Examples:

The following code defines an spu which uses the TONE spatom and creates an instance thereof.

[SPU tonegen a f p n sr out y]
t = tone
t $a $f $p $n $sr
y = t.y

[Macro spu_test]
#x := new SPU * tonegen 1 1000 0 1 44100
