Bytes2wavbytes

What is this?

• converts bytes to wav format
• as part of audio transcription pipeline

Why is repo?

• audio loading library, such as librosa, soundfile, and audioread, does not support loading audio from video format, such as mp4, webm.
• high level audio transcription server (vLLM) does not support video (yet)
• this repo bridges the gap by converting any media format to WAV ( a lossless format)
• this repo is intended to be a component of a larger audio transcription pipeline, such as librosa and vLLM

Convert bytes to wav format bytes

from bytes2wavbytes import bytes2wavbytes

input_file = "example_input.mp4"
output_file = "example_output.wav"
with open(input_file, "rb") as fin:
    input_bytes = fin.read()

    wav_bytes = bytes2wavbytes(input_bytes)
    with open(output_file, "wb") as fout:
        fout.write(wav_bytes)

Compatibility with librosa

import io
import librosa
from bytes2wavbytes import bytes2wavbytes

input_file = "example_input.mp4"
with open(input_path, "rb") as fin:
    input_bytes = fin.read()

wav_bytes = bytes2wavbytes(input_bytes)
bytes_ = io.BytesIO(wav_bytes)
y, sr = librosa.load(bytes_)
