Spletnum_channels ( int) – The number of channels bits_per_sample ( int) – The number of bits per sample. This is 0 for lossy formats, or when it cannot be accurately inferred. encoding ( str) – Audio encoding The values encoding can take are one of the following: PCM_S: Signed integer linear PCM PCM_U: Unsigned integer linear PCM SpletPlacing Colorbars. #. Colorbars indicate the quantitative extent of image data. Placing in a figure is non-trivial because room needs to be made for them. The first column has the same type of data in both rows, so it may be desirable to combine the colorbar which we do by calling Figure.colorbar with a list of axes instead of a single axes.
