Make a 'sound' object
Create a 'sound' object from a numeric vector.
A numeric vector representing a sound wave.
A string indicating the desired file name associated with this object.
The desired sampling frequency of the sound object.
This function can make a vector into a 'sound' object. If a filename is not set, the filename defaults to 'sound.wav' where 'sound' indicates the name of the sound variable that was passed to the function. The benefit of working with 'sound' objects is that they carry their sampling frequency and filename (as well as some other information) with them.

data (sound) ## take only the first 10000 samples from a 'sound' object tmp = sound$sound[1:10000] ## and make a new 'sound' object tmp = makesound (tmp, fs = 22050) tmp ## get ready to make two plots with thin margins #multiplot (2); par (mar = c(4,4,1,1)); ## and show a spectrogram of the original #spectrogram (sound) ## and the new, truncated version #spectrogram (tmp)
