Ossuary is a sound-design workstation. You feed a clip to a RAVE "brain" that has only ever heard one kind of sound, carve the result into weird one-shots, shape each hit, and index them into the sample library. Litany (and any other search client) plays them later.
pick a clip → interpret → carve hits → shape → index to library
Source & clip
Three ways to load a clip: search the sample library (results list under the field), 🎲 Random (pulls a random match for the query, or any random sample when the query is empty), or Upload a local file.
The Clip panel shows the decoded waveform with ▶ Audition and a zoom slider. Dragging across this waveform carves a dry phrase straight from the raw audio — see the Phrases section below.
Uploads can’t be interpreted (the brain needs a library media id), but everything client-side works on them: audition, zoom, and dry phrase carving + export.
Interpreter — brains & knobs
INTERPRET sends the clip through a RAVE model (a “brain”) that has only ever heard one kind of sound and re-hears your clip through it. The job runs server-side (submit → queue → run → fetch); one job at a time.
| Brain | Character |
|---|---|
percussion | Trained on drums; pushes everything toward rhythmic transients. The default for kit carving. |
vintage | Warm analog color — tape saturation and old-console character. |
nasa | Alien-transmission artifacts: static, telemetry, interference. |
VCTK | A speech brain; makes anything babble. |
musicnet | Classical chamber timbres — strings, winds, piano bleed. |
isis | Middle Eastern string resonance; long ringing sustains. |
sol_ordinario | Bowed strings, plain sustains only. |
sol_full | The full bowed-string palette, extended techniques included. |
darbouka_onnx | Hand drum — goblet-drum attack and slap. |
The knobs shape the pass in latent space:
Temperature (drift from a faithful re-hearing — 1.0 honest,
1.5+ hallucinating), Noise (random energy injected before
decoding), Wet/Dry (blend with the original), Shuffle (chops the latent timeline into chunks and deals them at random — the
value is chunk size),
Quantize (bit-crush in latent space),
Dims (touch only specific latent dimensions, e.g.
0,2,6; blank = all), and Reverse (flips the
latent trajectory while the audio plays forward). The
what do these knobs do? glossary in the panel has the same notes
inline.
Carving — hits, slots, bench
When an interpretation arrives it is auto-carved: onset detection finds the transients, every cut snaps to a zero crossing (no clicks), and each slice is classified by brightness (zero-crossing rate) and length into a slot:
| Slot | Heuristic |
|---|---|
kick | Dark — under ~1500 crossings/sec |
hi-hat | Bright — over ~5000, or short and bright |
perc | Mid-bright and ringing ≥ 240 ms — toms, congas, blocks |
snare | Everything left — cracks and claps |
Sensitivity re-tunes the onset detector (higher = more, smaller slices) — hit Re-carve to apply. Each slice is capped at 2 s.
Long clips carve hundreds of hits, so each slot auto-keeps only the strongest (the Keep slider, default 12/slot); the rest sit in a per-slot “+ N more” bench drawer, drawn dimmer on the waveform. + promotes a benched hit into the kit, − demotes. Raising the slider fills with the strongest benched; lowering trims the weakest kept — manual promotions survive.
On the waveform: click selects the nearest hit for editing; the colored ticks along the top are slice boundaries in each slot’s color. Every hit row has audition (▶), a merge checkbox (see Phrases), a slot dropdown to reassign, and ✕ to drop.
Editing a hit
Click a hit’s name (or its carve on the waveform) to open the editor. Everything auditions and exports rendered — what you hear is what you get.
- Trim handles — drag the edges on the mini waveform; both ends snap to zero crossings.
- Shape — Reverse, Normalize, Gain, and Pitch (baked into the render).
- Envelope — Attack / Decay edge fades with a Curve control. On a one-shot that’s a percussive gate; on a phrase it’s a gentle de-click.
- FX — Filter (cutoff/reso) + peaking EQ (freq/gain/Q), Delay (time/feedback/mix), Reverb (size/mix).
Audition loop
Each percussion slot header has a ↻ button: a minimal single-track loop that triggers that slot’s kept hits in rhythmic context, rotating through them round-robin. Deliberately not a sequencer — Litany owns sequencing; phrases never loop.
The default pattern is invisible and diagnostic: it seeds steps from the slot’s own onset timing, so you hear the rhythm the brain actually found. BPM / Rate / Length re-seed that default; touching Probability switches to a generated pattern.
Phrases — long samples
A phrase is any long material — a whole word, a spoken phrase, a melodic run, a texture pull — up to 15 seconds. Phrases are never auto-detected and never loop: they only exist because you carved one. They live in their own panel at the bottom of the page.
Two gestures
- Drag-select — drag across either waveform to paint a selection (ends snap to zero crossings; under 100 ms is discarded; over 15 s clamps with a hint). The bar that appears lets you audition the region, Carve as phrase, or clear. A plain click still selects the nearest hit.
- Merge slices — tick the checkboxes on two or more adjacent carved slices and hit Merge N slices → phrase. Merging consumes the source hits; Re-carve is the recovery path.
Dry vs wet
A phrase carved from the Clip waveform is
dry — no brain touched it, it survives re-interpretation,
and it indexes without model lineage (tagged
dry). One carved from the interpreted waveform is
wet (tagged interpreted) and dies with
its interpretation — a confirm guard warns first.
Each phrase row shows its origin badge and duration, and has an
optional name field — a named phrase exports as
that-name.wav instead of kit_phrase_2.wav.
Export — library & ZIP
Two destinations, from either export row. Index to library renders each hit and uploads it to
samples-bored, where Litany and search find it.
Download ZIP bundles the same renders locally (phrases
nest in a phrases/ folder).
The kit buttons (bottom of the carve panel) export
everything kept; the phrase buttons (Phrases panel) export
phrases only — so drums-only, phrases-only, and both are all one-click
workflows. The optional kit name becomes the filename prefix
and the kit: tag.
