Every sound from code

Every sound in Mossgrave is made by code we wrote, and nothing is recorded or borrowed. Two little synthesisers do all of it.

Tonestack makes every sound effect. Each sound is a short stack of tones, each with its own pitch sweep, volume envelope and filter, plus a single echo. An axe bite, a splash, a level-up and a dragon's roar are all just different recipes.

Wavecard makes all the music. It plays tiny instruments that are themselves generated in code, an ocarina, a reed, strings, a finger bass and a kalimba, through a small room at 22,050 Hz. The first two tracks are Mossgrave Green for the Heartland and Marsh Lanterns for the night.

One rule sits over all of it: nothing high-pitched or jarring. Lower notes, soft attacks, a gentle top end. You will be hearing these sounds for hours, and they should feel like a fire in the next room, not an alarm. Every creature family will get its own roar in the same style, and bigger creatures sound lower and longer.
