WaveFile::Buffer#samples

Returns the sample data contained in the Buffer as an Array. If the Format has 
1 channel, the Array will be a flat list of samples. If the Format has 2 or more 
channels, the Array will include sub arrays for each sample frame, with a sample 
for each channel.

Examples

  samples = mono_buffer.samples
  # => [-0.5, 0.3, 0.2, -0.9, ...]

  samples = stereo_buffer.samples
  # => [[-0.2, 0.5], [0.1, 0.2], [-0.4, 0.7], [0.1, 0.2], ...]

  samples = three_channel_buffer.samples
  # => [[0.3, 0.5, 0.2], [-0.1, 0.2, -0.9], [0.2, 0.3, -0.4], [0.1, 0.2, -0.8], ...]
