Read or write INFO chunks in WAV files

Project description

wav-chunk

Read or write INFO chunks from a RIFF WAV file.

Installation

$ pip install wavchunk

Dependencies

  • Python 3.6 or higher

Usage

By default, wavchunk adds or gets INFO chunk bytes after the WAV data chunk.

Add INFO chunk

import wavchunk

with open("infile.wav", "rb") as in_file:
    with open("outfile.wav", "wb") as out_file:
        wavchunk.add_chunk(in_file, "my data".encode(), out_file=out_file)

Get INFO chunk

import wavchunk

with open("infile.wav", "rb") as in_file:
    my_data = wavchunk.get_chunk(in_file).decode()
    print(my_data)

Command-Line Interface

The wavchunk module can also be used from the command-line. By default, WAV data is expected on stdin and is written to stdout so that commands can be chained together in a pipe.

Add INFO chunk

$ python3 -m wavchunk add --data 'my data' < infile.wav > outfile.wav

Get INFO chunk

$ python3 -m wavchunk get --data - < infile.wav
<data from chunk>

Delete INFO chunk

$ python3 -m wavchunk get --delete --data mydata.bin < infile.wav > outfile.wav
