## What Is Batch Processing?

Batch processing is processing a chain of effects in preset order, either on tracks in the active Audacity project window or on a number of imported audio files. This can save time and repetitive effort. Examples of typical usage:

- Compressing the dynamic range of a number of WAV files, then converting them to MP3
- Noise removing, bass boosting then normalizing a track or tracks in a project

## How to Use Batch Processing

- To set up a chain of batch commands, choose File > Edit Chains...
- To apply the chain to files or to the current project, choose File > Apply Chain...
