normalize | R Documentation |
Multiply the waveform of a Sample object or a wav file with a positive constant so that the maximum absolut value becomes 1, or any other specified constant.
Use this command before saving or playing a Sample object to avoid cracks in the sound caused by parts in the waveform that exceed the range [-1,1].
normalize(s, level=1)
s |
a Sample object, or a string giving the name of a wav file. |
level |
a number between 0 and 1 specifying the desired maximum absolute value of the waveform. |
a Sample object with the specified maximum absolut value of the waveform.
