spdl.io.AudioFrames

class AudioFrames

Audio frames.

Methods

clone()

Clone the frames, so that data can be converted to buffer multiple times.

Attributes

num_channels	The number of channels.
num_frames	The number of audio frames.
sample_fmt	The name of sample format.
sample_rate	The sample rate of audio.

__len__() → int

Returns the number of frames. Same as num_frames.

clone() → AudioFrames

Clone the frames, so that data can be converted to buffer multiple times.

Returns:

A clone of the frame.

property num_channels: int

The number of channels.

property num_frames: int

The number of audio frames. Same as __len__ method.

Note

In SPDL, The number of samples == the number of frames x the number of channels

property sample_fmt: str

The name of sample format.

Possible values are

• "u8" for unsigned 8-bit integer.

• "s16", "s32", "s64" for signed 16-bit, 32-bit and 64-bit integer.

• "flt", "dbl" for 32-bit and 64-bit float.

If the frame is planar format (separate planes for different channels), the name will be suffixed with "p". When converted to buffer, the buffer’s shape will be channel-first format (channel, num_samples) instead of interweaved (num_samples, channel).

property sample_rate: int

The sample rate of audio.
