Audio Decode Implementation With PyAV

author: Junjie Jiang

Description

Audio Decode converts the encoded audio back to uncompressed audio frames. In most cases, audio decoding is the first step of an audio processing pipeline.

Code Example

import towhee

towhee.glob('./music.mp3').audio_decode.ffmpeg().flatten().show(limit=1)


# batch decode
# towhee.glob('./music.mp3').audio_decode.ffmpeg(500).flatten().show(limit=1)

Factory Constructor

Create the operator via the following factory method:

audio_decode.ffmpeg()

batch decode, batch_size = 100:

audio_decode.ffmpeg(100)

Interface

An audio decode operator takes an audio file path as input. It decodes the audio back to audio frames.

Args:

audio (str):

Audio file path.

Return (generator):

An generator over audio frames with type towhee.types.AudioFrame.
