Sine {sound}

Create Sample Objects for the Basic waveforms

Description

Create a Sample object with a sine, sawtooth, or square waveform, silence, or noise.

Usage

Sine(freq, dur, rate=44100, bits=16, channels=1)
Sawtooth(freq, dur, rate=44100, bits=16, channels=1, reverse=FALSE)
Square(freq, dur, rate=44100, bits=16, channels=1, upPerc=50)
Silence(dur, rate=8000, bits=8, channels=1)
Noise(dur, rate=44100, bits=16, channels=1)

Arguments

freq

the frequency (a double).

dur

the duration in seconds (a double).

rate

the sampling rate, an integer between 1000 and 48000.

bits

the sampling quality in bits per sample, 8 or 16.

channels

1 for mono, or 2 for stereo.

reverse

logical. If TRUE, the waveform will be mirrored vertically.

upPerc

a number between 0 and 100 giving the percentage of the waveform with value +1.

Details

If channels=2, left and right side of the sample will be the same for Sine, Sawtooth and Square. For Noise, both sides will be generated separately, using runif.

Value

a Sample object.
