Usage

You can use the CartChunk class to read CART CHUNK headers as well as riff and fmt data of a wave file:

from cart_chunk import CartChunk
from pathlib import Path

src = Path('/path/to/wave/file.wav')

wav = CartChunk(src)

if wav.is_scott:
    for key, value in wav.scott_data.items():
        print(f'{key:<20}: {value}')
else:
    print('Does not contain CART CHUNK')

for key, value in wav.riff_data.items():
    print(f'{key:<20}: {value}')

for key, value in wav.fmt_data.items():
    print(f'{key:<20}: {value}')

for key, value in wav.data_meta.items():
    print(f'{key:<20}: {value}')

Use the CartChunk class to write a new copy with the CART CHUNK. The following keyword args are available:

• artist str
• title str
• trivia str
• year int
• category str
• cart str
• intro float
• sec float
• eom float
• start_timestamp tuple
• end_timestamp tuple
• hrcanplay list[list[int]]

from cart_chunk import NewCart

new_file = Path('/path/to/new/file.wav')

new_cart = NewCart(new_file, artist='artist', title='title')

wav.write_copy(new_cart)
