Convert MSS to AFC

Understanding the mss and afc file formats

MSS files are typically audio script or subtitle files used in video games, especially those developed by Konami. They often contain timing and text data for in-game dialogue or subtitles. AFC files, on the other hand, are compressed audio files used in various video games, notably by Electronic Arts. AFC stands for Adaptive Frequency Coding, and these files store actual audio data, such as voice lines or sound effects.

Why convert mss to afc?

Converting MSS to AFC is not a standard or direct process, as these formats serve different purposes: MSS is for scripts or subtitles, while AFC is for audio. However, in some game modding scenarios, users may want to convert subtitle scripts into spoken audio (using text-to-speech) and then encode that audio into the AFC format for in-game use.

How to convert mss to afc

Since there is no direct converter from MSS to AFC, the process involves two main steps:

1. Extract text from the MSS file: Open the MSS file with a text editor or a specialized subtitle tool to extract the dialogue or script lines.
2. Convert text to audio: Use a text-to-speech (TTS) tool to generate audio files (such as WAV or MP3) from the extracted text.
3. Convert audio to AFC: Use an audio converter that supports AFC encoding to convert the generated audio files into the AFC format.

Recommended software for conversion

• Subtitle Edit (for extracting text from MSS files): Open your MSS file and export the text.
• Balabolka (for TTS conversion): Use File → Open to load your text, then File → Save Audio File to export as WAV or MP3.
• EA Layer 3 Encoder (EALayer3) or vgmstream (for audio to AFC): Use command-line tools to convert WAV/MP3 to AFC. For example, with vgmstream, use vgmstream-cli -o output.afc input.wav.

Summary

While there is no direct MSS to AFC converter, you can achieve the conversion by extracting text, generating audio, and encoding it to AFC using the recommended tools. This workflow is especially useful for game modders who want to add custom voice lines to games that use the AFC audio format.
