pygame.sndarray

Functions to convert between NumPy arrays and Sound objects. This module will only be available when pygame can use the external NumPy package.

Sound data is made of thousands of samples per second, and each sample is the amplitude of the wave at a particular moment in time. For example, in 22-kHz format, element number 5 of the array is the amplitude of the wave after 5/22000 seconds.

Each sample is an 8-bit or 16-bit integer, depending on the data format. A stereo sound file has two values per sample, while a mono sound file only has one.

pygame.sndarray.array()

copy Sound samples into an array

array(Sound) -> array

Creates a new array for the sound data and copies the samples. The array will always be in the format returned from pygame.mixer.get_init().

pygame.sndarray.samples()

reference Sound samples into an array

samples(Sound) -> array

Creates a new array that directly references the samples in a Sound object. Modifying the array will change the Sound. The array will always be in the format returned from pygame.mixer.get_init().

pygame.sndarray.make_sound()

convert an array into a Sound object

make_sound(array) -> Sound

Create a new playable Sound object from an array. The mixer module must be initialized and the array format must be similar to the mixer audio format.

pygame.sndarray.use_arraytype()

Sets the array system to be used for sound arrays

use_arraytype (arraytype) -> None

DEPRECATED: Uses the requested array type for the module functions. The only supported arraytype is 'numpy'. Other values will raise ValueError.

pygame.sndarray.get_arraytype()

Gets the currently active array type.

get_arraytype () -> str

DEPRECATED: Returns the currently active array type. This will be a value of the get_arraytypes() tuple and indicates which type of array module is used for the array creation.

New in pygame 1.8.

pygame.sndarray.get_arraytypes()

Gets the array system types currently supported.

get_arraytypes () -> tuple

DEPRECATED: Checks, which array systems are available and returns them as a tuple of strings. The values of the tuple can be used directly in the pygame.sndarray.use_arraytype() () method. If no supported array system could be found, None will be returned.
