Just a silly little script to convert Blackrock ns5 or ns6 files to audio.

Prerequisites

• Install dependencies. I use uv.

Usage

As long as you have a Python environment with the required dependencies installed then it's just a matter of calling the ns2audio.py script with arguments.

I use uv so I typically run it with uv run ns2audio path/to/my.ns5

 Usage: ns2audio.py [OPTIONS] FILEPATH

• chidx -- 1-based index to the channel that will be converted. You can provide more than 1 integer by editing the script if you want stereo audio files.
• start-time -- in seconds since the beginning of the file

Tested in Python 3.12 on MacOS ARM.
