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.
