Clipify

An Ableton Live 12 extension for chopping audio takes. Right-click an arrangement audio clip (or a time selection on an audio track) → Clipify… to open a popup that previews the cuts over a waveform and splits the clip at the quiet gaps — for turning a vocal take into individually-editable pieces.

Slice & Strip popup

• MODE — MACRO separates groups of sound with real silence between them (phrase level); MICRO separates individual audio events (word/transient level). Each mode keeps its own Sensitivity; the slider swaps between them.
• STRIP SILENCE — Off just slices; Deactivate / Delete also isolate the noise-floor stretches (including leading/trailing silence) and mute or remove them. The Silence slider grows each stripped zone from the dead-quiet middle out to the full gap.
• Cuts keep a note's decay tail with that note and the pre-note breath with the following note, and snap to the nearest zero crossing so splits don't click.
• Controls persist across runs (clipify-settings.json in the storage directory).

A standalone Split at Nearest 0 Crossing acts on the cursor (no time range).

How it works

Each cut is an in-place split (clearClipsInRange(t, t)), so every piece keeps the original clip's warp, fades, gain, and pitch. Heavy DSP runs once in the extension; the popup does the interactive selection; then the splits and strip apply as one grouped undo.

silence.ts     PCM         ──▶ sound segments + RMS   (amplitude detection)
candidates.ts  segments    ──▶ cut candidates         (gaps, deep-silence extent, zero-cross snap)
envelope.ts    PCM         ──▶ waveform peaks          (popup canvas)
mapping.ts     file-second ──▶ arrangement beat        (warp curve, or constant rate)
popup.html     candidates  ──▶ chosen cuts + strips    (mode / sensitivity / strip — interactive)
slicer.ts      orchestrates decode → popup → apply

extension.ts registers the right-click commands; settings.ts persists the popup state; debug.ts holds the gated evaluation logging.

Build & run

Needs Node ≥ 24.14.1 (the script finds one).

./build.sh run      # build + launch in Live's Extension Host (dev mode)
./build.sh dev      # dev bundle only
./build.sh          # production .ablx in dist/

Live 12 Beta must be running with Developer Mode on; Ctrl-C and re-run per change. run does a warm-up launch first to work around Live's cold-start handshake (which otherwise needs two runs), and passes a .clipify-dev/ storage directory so settings persist in dev.

Tuning

• DETECT_PARAMS (silence.ts) — detection thresholds and gates.
• DEEP_MARGIN_DB (candidates.ts) — how close to the noise floor counts as silence.
• threshold mappings in popup.html (thresholdFor) — per-mode sensitivity curves.
• debug (debug.ts) — new Debug(true) → false to silence logging.

Known limitation

On clips with heavy non-linear warp, cut positions are approximate: the file-second → beat mapping interpolates the clip's warp markers, which Live reports for only part of the clip.
