nullSample: The NULL Sample Object

In sound: A Sound Interface for R

Description

Create a Sample object whose waveform has length 1 and value 0. Often useful to initialize loops.

Usage

nullSample(rate=44100, bits=16, channels=1)

Arguments

rate	the sampling rate, between 1000 and 48000.
bits	the sample quality (number of bits per sample), 8 or 16.
channels	1 for mono, or 2 for stereo.

Value

a Sample object.

Note

Future versions may use a special NULLSample flag instead of using a sample of length 1.

for (f in scale)
  s <- appendSample(s,Sine(f*base,1))
play(s)
