BPM Counter

About

BPM Counter is a simple browser extension that helps you detect the beats per minute of a song playing in your current tab. Use it when you need a clean BPM finder, tempo detector or music BPM counter without opening a heavy audio app. 
The extension opens in a side panel, so the page with audio stays visible while you check the result.
⚡ What it does
This tool listens to the active tab after you press Detect BPM and shows a clear tempo estimate. It is made for one focused task: find BPM for browser audio and display the number without technical noise.
You can use it to:
check song tempo


detect BPM in a track


use a BPM checker for quick reference


compare beats per minute between songs


run a song BPM finder while browsing


open a tempo finder next to the music page


use an automatic BPM detector without manual input


The workflow stays short and predictable.
🎵 How to use it
Open a page with music or a track


Launch the extension from the toolbar


Start the analysis


Wait while the signal is checked


Get the result, for example: 128 BPM


Run another check when needed


The extension does not start analysis automatically. You control when the listening begins.
🔎 Made for browser music
This tool is useful when you want to count BPM song tempo while listening in Chrome or another Chromium-based browser. It is not built around file uploads, audio editing or complex production tools.
It works well for quick checks:
a DJ checking a track speed


a musician comparing rhythm


a dancer preparing a reference


a video creator choosing music pace


a teacher explaining beats per minute


a listener trying to understand song BPM


The side panel format keeps the extension close to the page, but separate from the website interface.
🎚️ Clean tempo detection
Some tools are built for manual rhythm input. This extension focuses on automatic detection. Start your song, press the button and let the tempo detector estimate the rhythm signal.
You do not need to follow the beat by hand.
You do not need to paste a link into another page.
You do not need to upload an MP3 file.
The result is shown in a simple format:
128 BPM
No confidence score.
No peak values.
No debug data.
No alternative calculations.
Only the number you need for a quick tempo check.
🧩 Why the side panel matters
A popup can disappear when focus changes. This extension uses a side panel so you can keep the tool open while you continue using the page.
This is helpful when you need to:
test several songs


compare different tracks


repeat a BPM check


keep the result visible


continue browsing while the panel stays open


The panel is designed to feel like a small built-in browser instrument.

📌 When it helps
Use this extension when you need to understand the pace of music quickly. It can help during music selection, reference work, dance preparation, video editing, teaching or casual listening.
Instead of guessing the rhythm by ear, you can run a short check and get a readable result.
The product is intentionally small. It does not try to replace professional DJ software or a full audio workstation. It gives one browser-based function and keeps that function easy to reach.
🎼 Search intent it covers
People may search for a BPM counter app, an app BPM counter, a BPM counter online tool, or a way to find BPM inside the browser. This extension is built for that same core task, but keeps the experience focused on the active tab.
It can help when you want to:
find BPM for a song


check beats per minute


detect song tempo


use a tempo detector without a separate page


run a quick BPM count for a track


understand rhythm before using music in another workflow
