# Audio Split Export
> Cut one recording into many separate audio files — either at silences it detects automatically, or at time ranges you specify.
## What this node does
**Audio Split Export** takes a single audio source and writes out multiple audio files, one per segment. Segments come from one of two modes: it can **detect silence** and split on the gaps, or take an explicit **JSON list** of start/end times. Each exported piece gets a short fade to avoid clicks, and the files are named by a chosen scheme.
It accepts a `COMFYTV_AUDIO` snapshot or a `COMFYTV_VIDEO` (its audio track is used; audio takes priority). It outputs a `COMFYTV_TEXT` listing the exported files and has a ▶ **Run** (FFmpeg does the cutting).
To feed native ComfyUI `AUDIO` in or out, insert a **Bridge** — see [bridges.md](https://github.com/jtydhr88/ComfyTV/blob/main/docs/bridges.md).
## When to use it
* Break a long recording of separate phrases or sound effects into individual clips.
* Auto-split a voice take into sentences by trimming on the pauses.
* Export exact time ranges (e.g. from a cue sheet) as their own files.
## Parameters
### detect
How segment boundaries are found: `silence` (default) splits automatically on quiet gaps; `json` uses the ranges you provide in **segments**.
### threshold\_db
Loudness below which audio counts as silence, in dB. Range **-90 to -20**, default **-60**. `silence` mode only. Raise it (toward -20) if quiet passages are being treated as sound and not split.
### min\_silence\_s
Minimum length a quiet gap must last to be treated as a split point, in seconds. Range **0.01 to 5**, default **0.5**. `silence` mode only.
### min\_segment\_s
Minimum length a segment must have to be exported, in seconds. Range **0.01 to 10**, default **0.1**. Discards tiny slivers.
### fade\_ms
Fade in/out applied to each exported segment, in milliseconds. Range **0 to 500**, default **1.45**. A tiny fade prevents clicks at the cut edges.
### naming
How exported files are named: `num_and_prefix` (default, number + the **prefix**), `num_and_name` (number + source name), or `name` (source name only).
### prefix
The text used in the filename when **naming** is `num_and_prefix`. Default **`segment`**.
### segments
A JSON list of ranges for `json` mode, in the form `[{"start": s, "end": s}, ...]` (times in seconds). Ignored in `silence` mode. Required (non-empty) when **detect** is `json`.
## Outputs
| Output | Type | Meaning |
| --------- | -------------- | ------------------------------------ |
| **files** | `COMFYTV_TEXT` | A list of the exported segment files |
## Tips
* In `silence` mode, if it splits too much, raise **min\_silence\_s** and/or lower **threshold\_db**; if it doesn't split enough, do the opposite.
* Increase **min\_segment\_s** to throw away breaths and stray noises that would otherwise become their own tiny files.
* `json` mode is exact and repeatable — use it when you already know the cut points.
