# How to tune inference clipping
|
|
|
|
Use this guide when long recordings need to be split into smaller clips during
|
|
inference.
|
|
|
|
## What clipping controls
|
|
|
|
`InferenceConfig.clipping` controls how recordings are split before batching.
|
|
|
|
Key fields are:
|
|
|
|
- `duration`:
|
|
clip duration in seconds,
|
|
- `overlap`:
|
|
overlap between adjacent clips,
|
|
- `max_empty`:
|
|
how much empty padding is allowed,
|
|
- `discard_empty`:
|
|
whether empty clips are dropped.
|
|
|
|
## Start from the defaults
|
|
|
|
Use the built-in clipping behavior first unless you already know you need
|
|
something else.
|
|
|
|
Only tune clipping when:
|
|
|
|
- recordings are much longer than your normal working set,
|
|
- you are seeing edge effects around calls,
|
|
- you need tighter control over throughput or padding behavior.
|
|
|
|
## Override clipping with an inference config
|
|
|
|
Create an inference config file and pass it to `process` or `evaluate`.
|
|
|
|
Example:
|
|
|
|
```yaml
|
|
clipping:
|
|
enabled: true
|
|
duration: 0.5
|
|
overlap: 0.1
|
|
max_empty: 0.0
|
|
discard_empty: true
|
|
loader:
|
|
batch_size: 8
|
|
```
|
|
|
|
Run with:
|
|
|
|
```bash
|
|
batdetect2 process directory \
|
|
path/to/model.ckpt \
|
|
path/to/audio_dir \
|
|
path/to/outputs \
|
|
--inference-config path/to/inference.yaml
|
|
```
|
|
|
|
## Validate clipping changes on a small reviewed subset
|
|
|
|
Changing clipping changes what the model sees per batch and can change how
|
|
events near clip boundaries behave.
|
|
|
|
Check a reviewed subset before applying clipping changes to a full project.
