Octo

Chipify

Chipify is a Python script that filters and encodes audio for Octo with the XO-Chip extended instruction set. It takes as input a mono-channel WAV file, and spits out both a preview WAV file (*.out.wav) as well as a text file with base 16-encoded bytes suitable for Octo (*.out.txt).

Requirements:

Chipify requires the following to run:

• Python 3.8 or higher
• NumPy, which must be installed separately

Installing:

1. Make sure you’ve created & activated a virtual environment
2. Run pip install -r requirements.txt to gather and install the requirements

You can also try pipx to install to your user account instead of a single venv.

Usage:

python chipify.py FILENAME

Try it out:

Here is a simple Octo program that will play all data encoded after the data label. Copy the data from your output file into the data block and listen!

: main
	v0 := 16
	v1 := 2
	i := data
	loop
		audio
		buzzer := v0
		delay := v1
		wait
		i += v0
	again

: wait
	loop
		vf := delay
		if vf != 0 then
	again
;

# Replace this with your audio
: data 0xFF 0x00 0xFF 0x00 0xFF 0x00 0xFF 0x00 0xFF 0x00 0xFF 0x00

Chipify was written by blastron and updated for Python 3 by pushfoo.
