spdl.io.AudioEncoder¶

class AudioEncoder¶

Audio encoder.

Returned by Muxer.add_encode_stream().

Attributes

`encode`	Encode audio frames.
`flush`	Notify the encoder of the end of the stream and fetch the buffered packets.
`frame_size`	The number of frames that the internal encoder can handle at a time.

encode¶

Encode audio frames.

Parameters:: frames – Audio frames. Use create_reference_audio_frame() to convert tensor/array objects into frames.
Returns:: Packets objects if encoder generates one.

flush¶: Notify the encoder of the end of the stream and fetch the buffered packets.

property frame_size¶

The number of frames that the internal encoder can handle at a time.

Some audio encoders are strict on the number of frames it can handle at a time. In such case, retrieve the number of expected frames (par channel) here, slice data accordingly, then encode slice by slice.
