## About

## What it does
Audio Merge combines two or more audio files into a single binary output. Send the files in the request body as repeated `files` entries, and get one merged audio file back.

Use it when you need to stitch clips together before playback, publishing, or downstream processing. For example, you might combine intro, voiceover, and outro tracks into one file for a podcast workflow, or join short recordings into a single deliverable for review.

The endpoint is designed for simple file handling: each input file can be up to 30 MB, and the response is the merged audio file itself as binary data. There are no extra transformation options or metadata fields to manage, so integration stays straightforward.

If your application already receives separate audio assets and needs one consolidated result, Audio Merge gives you a direct way to do that without adding a separate media-processing pipeline.
