- **Category:** Media

- **Keywords:** audio, fingerprint, hash, analysis, ffmpeg

## Overview

Downmixes and downsamples audio, then hashes the raw PCM stream to create a stable fingerprint for matching.

## Inputs

- **Audio File** (file): Select an audio file
- **Analysis Seconds** (text): e.g., 120

## When to use

- When you need to identify duplicate or similar audio files in a large collection.
- For audio analysis where a compact representation of sound is required, such as in media libraries.
- To generate fingerprints for audio matching applications like music recognition or copyright detection.

## How it works

- Upload an audio file in a supported format via the audio file input.
- The tool downmixes the audio to mono and downsamples it to a standard rate.
- It hashes the raw PCM stream to produce a unique fingerprint.
- The result is returned as a JSON object containing the fingerprint data.

## Use cases

- Deduplicating audio files in a music library to save storage and organize collections.
- Identifying audio content in user-generated media for moderation or compliance purposes.
- Building a music recognition service by comparing fingerprints against a database of known tracks.

## Frequently asked questions

### What is an audio fingerprint?

An audio fingerprint is a condensed digital summary of an audio signal, used to identify or match audio content based on its acoustic properties.

### What audio formats are supported?

The tool supports common audio formats like MP3, WAV, FLAC, and others through the audio file input.

### How long does the analysis take?

Analysis time depends on the file size and the analysis seconds setting; it processes the first 120 seconds by default for efficiency.

### Is the fingerprint unique for each audio file?

Fingerprints are designed to be robust and unique for distinct audio, but identical audio files will produce matching fingerprints.

### Can I analyze more than 120 seconds of audio?

Yes, you can adjust the analysis seconds parameter to analyze a longer portion of the audio file, up to the file's duration.
