A Ruby gem for reading and writing sound files in Wave format (*.wav)
As an example, suppose a `"fmt "` chunk has a stated size of 30 bytes, and the format code is not `1` (and therefore the chunk should have an extension)....
Consider the following code: ``` require 'wavefile' include WaveFile #1 second 440 Hz square wave format = Format.new(:mono, 16, 44100) writer = Writer.new("square.wav", format) cycle = ([2**15] * 50) +...
Normally, the `"fmt "` chunk has an expected size based on the format code. For example: * Format code `1` (Integer PCM): 16 bytes * Format code `3` (Floating point...
