## Overview

Downmixes to mono, analyzes a short window, and estimates tempo using beat tracking.

## Inputs

- **Audio File** (file): Select an audio file
- **Analysis Seconds** (text): e.g., 60

- When you need to quickly determine the tempo of a song for DJ mixing or beatmatching.
- When organizing a music library by BPM to create playlists with consistent energy levels.
- When analyzing audio tracks for music production to align tempos in compositions or remixes.

## How it works

- Upload an audio file in a supported format, such as MP3 or WAV.
- Optionally specify the analysis duration in seconds; the default is 60 seconds.
- The tool converts the audio to mono and analyzes a segment for beat patterns.
- It estimates the BPM using beat tracking algorithms and outputs the result as JSON.

## Use cases

- DJs matching song tempos for seamless transitions during live performances.
- Music producers analyzing reference tracks to set project tempos in digital audio workstations.
- Fitness instructors creating workout playlists with consistent BPM for rhythm-based exercises.

## Frequently asked questions
