## Audio
2022-08-28 17:33:41 +00:00
This game used [HexoDSP ](https://github.com/WeirdConstructor/HexoDSP ) for audio synthesis.

The synthetizer matrix can be edited using [HexoSynth ](https://github.com/WeirdConstructor/HexoSynth ) visual editor.

However we could not get this working in WASM, hence we used simple playback audio instead for the jam. The concept of procedural audio is not abandonned but it will be for another time.
