ipytone.AudioBuffer#

class ipytone.AudioBuffer(**kwargs: Any)#

Bases: ToneObject

Audio buffer loaded from an URL or an array.

Parameters:

url_or_array (str or array-like or array widget) – Buffer file (URL) or data.
sync_array (bool, optional) – If True, the array trait will be synchronized as soon as the audio buffer is loaded in the front-end (default: False). It is ignored if an array is already given as buffer data or if the duration of the buffer exceeds 10 seconds.
reverse (bool, optional) – If True, the audio buffer is reversed (default: False).

__init__(url_or_array, sync_array=False, reverse=False, **kwargs)#: Public constructor

Methods

Dispose and disconnect this node.

Attributes

`array`	A trait type representing a Union type.
`buffer_url`	Buffer loaded from this URL (None if an array is used)
`disposed`	Returns True if the node was disposed (i.e., disconnected and web audio node freed for garbage collection).
`duration`	Buffer duration in seconds (0 if not loaded)
`length`	Buffer size in samples (0 if not loaded)
`loaded`	True if the audio buffer is loaded
`log`	A trait whose value must be an instance of a specified class.
`n_channels`	Number of discrete audio channels (0 if not loaded)
`reverse`	True if the buffer is reversed
`sample_rate`	Buffer sample rate (0 if not loaded)
