Heads up

This thing hasn't been tested a whole lot, so there are probably bugs. If you find one, feel free to report it - just be cool about it. I only listen to feedback from people who are reasonable and polite. Bugs get fixed when I have free time.

About

This is a graphical frontend for editing music in Need for Speed Carbon and Most Wanted. It wraps the command-line tools (MPFmaster, FFmpeg, sx) into a single window so you don't have to mess with batch files or command prompts.

The tool lets you unpack MUS/MPF archives, convert ASF audio to WAV for editing, then convert back and repack. It's designed to make the music modding workflow faster and more accessible.

Features

- Unpacks and repacks MUS / MPF archives

- Converts ASF <-> WAV in one or two clicks

- Side-by-side file list (ASF on left, WAV on right)

- Built-in player so you can preview tracks

- Replace individual tracks with your own WAV files

- Works with English and Chinese UI

Supported games

- Need for Speed Carbon

- Need for Speed Most Wanted

- Probably other NFS titles that use the same MUS/MPF format (untested)

How to use

1. Click "Select MUS File" and pick your .mus file. The matching .mpf is found automatically.

2. Pick a mode:

One-Click Full Convert - extracts everything and converts all ASF to WAV. Good if you want to edit multiple tracks.

Extract ASF Only - just pulls out the ASF files. Convert them one by one as needed.

3. Edit the WAV files in your audio editor of choice. 44100 Hz / 16-bit is recommended.

4. Convert your edited WAVs back to ASF.

5. Hit "Pack to MUS" to rebuild the archive. Your original files get backed up automatically with a timestamp.
