bank

Every synthesised sound in the game, and the bake that files it: ten beds and twenty-nine one-shots, computed from `audio.dsp` and written to `/zero/source/audio/clips/<name>.soundClip`.

What it does

audio.bank

Every synthesised sound in the game, and the bake that files it: ten beds and twenty-nine one-shots, computed from audio.dsp and written to /zero/source/audio/clips/<name>.soundClip.

Run from an execute, never from a component — a create made inside a component callback is filed in the ephemeral runtime store and never reaches the commit.

local bank = require("audio.bank")
bank.bake()                       -- all thirty-nine, in interactive-first order
bank.bake({ "music_battle" })     -- one
bank.render("titan_roar")         -- the samples, written nowhere

RECIPES is the whole catalogue: a sample rate, whether it loops, and the function that renders it. Rates are chosen by what the clip has to carry — a bed stores as raw PCM, so its rate is also its size, and the wind has nothing above 6 kHz worth paying for where massed rifle fire does.

bake returns { ok, lines }, one line per clip with its frame count, duration, codec and, for a bed, its loop-seam ratio.

# audio.dsp The arithmetic every sound in KESSREL LINE is made of: oscillators (sine, triangle, a reedy partial stack), white noise, one-pole and state-variable filters, soft clipping, normalisation, a Schroeder reverb for the canyon and a single hard slapback off its wall, the two loop-seam tools a bed is written with, and `bake`, which encodes raw interleaved f32 PCM into a `.soundClip`. Pure CPU: no network, no credit, no service. `audio.bank` and `audio.voicebank` are its only consumers. ```lua local D = require("audio.dsp") local n = 48000 // 2 local b = D.mk(n) D.noise(b, n, 48000, D.env(1.0, 0.002, 26)) D.svf(b, n, 48000, 2400, 1.4, "band") D.reverb(b, n, 48000, 0.3, 0.85) D.normalise(b, n, 0.9) D.bake("a_crack", "audio/clips", b, n, 48000, 1, false) ``` A clip that loops is baked with `loop = true`, which stores it as `codec = "pcm"` and measures `audio.loopSeam` on the payload. `bedBuffer`, `wrapFold` and `cyc` are what make that seam survive: a bed is rendered longer than it plays and folded back over itself, and its tonal layers sit on frequencies that complete a whole number of cycles across the loop. `bake` returns a report rather than raising, so a whole bank bakes and says what failed instead of stopping at the first one. The generator and filter shapes follow `game.vendor.synth` (RED DOT RISING, ZeroMind `d145323d`), re-exported here as a toolkit rather than a fixed bank.
