audio-split

An audio-file cutter that uses FFmpeg to divide one file into two parts at a chosen time or percentage.

In plain words
What is it for?
Splitting recordings, separating an intro from the main content, or cutting a clip at a timestamp.
Why use it?
It avoids manually editing audio when you only need separate sections of one clip.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

audio-split scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Audio Split

Split one audio file into part 1 (start �?split point) and part 2 (split point �?end).

Rules

When this skill applies, read and follow skill-dependency-manager �?run scripts as documented, install missing tools into .dependency/.

Quick Start

Default: split at 50% of duration, output to <audio-dir>/audio-split/:

.dependency/python/python .ai/audio-split/split.py --audio path/to/audio.wav

Split at a specific time (seconds):

.dependency/python/python .ai/audio-split/split.py --audio path/to/audio.wav -s 1.25

Outputs: basename_part1.ext and basename_part2.ext.

Split Point

Provide one of:

Flag Meaning
-s / --split-at Time in seconds (e.g. 1.25, 90)
-p / --percent Position as percent of duration (e.g. 50 = midpoint)
(none) Defaults to 50%

If both -s and -p are given, -s wins.

Common Flags

--audio · -s / --split-at · -p / --percent · -o / --output

.dependency/python/python .ai/audio-split/split.py --audio audio/sfx.wav -s 0.4
.dependency/python/python .ai/audio-split/split.py --audio audio/sfx.wav --output path/to/out/

Originals are never modified. Supported: .wav, .mp3, .ogg, .flac, .aac, .m4a, .wma.

Agent Notes

  1. Use the bundled script, not hand-written -ss/-to commands.
  2. Looping BGM �?splitting breaks the loop; prefer two source assets or manual crossfade planning.
  3. Split point at 0 or at/after duration �?script errors with a clear message.
  4. Missing Python/FFmpeg �?populate .dependency/ per skill-dependency-manager, retry same command.
  5. FFmpeg details and manual fallback: reference.md

Tests

From repo root:

.dependency/python/python .ai/audio-split/test_split.py

Manual CLI examples: cli/audio-split.md

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

audio-split is a skill published in the GitHub repository godot-fun/godot-framework (116 stars, last pushed 3d ago), licensed MIT. It adds 58 tokens to every session and 631 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
