About — Click Track Generator

The Story

Every working band eventually faces a lineup change. For one rock cover band, that moment came when their keyboardist — a core member who had anchored the sound for years — decided to retire. On a personal level, it was a milestone worth celebrating. On the setlist, it left a serious gap.

Keyboards aren't optional texture in a rock cover band with a catalog that leans on artists like Journey, Night Ranger, Billy Idol, Mötley Crüe, Bad Wolves, and Bryan Adams. Those keyboard parts are structural. You don't play "Don't Stop Believin'" without keys and call it a shortened arrangement — you play a fundamentally different song. The band needed a way to fill that space, and the answer was backing tracks.

Purchasing professional multi-track backing tracks from services like karaoke-version.com is a solid solution — the audio quality is there, and the arrangements are faithful to the originals. But those tracks ship with their own standard click track sound and it's not for everyone. He found such click tracks to be harsh and wearing on the ears throughout a 4 set gig and decided he needed a click track with a sound he felt was tolerable to listen to for 4 hours.

The musician behind this tool searched for a clean, browser-based solution and didn't find one that met the standard. So he built it himself.

What It Solves

The Click Track Generator was built to answer one specific need: generating a clean, fully customizable click track that syncs with any backing track, stem, or isolated audio source — instantly, in the browser, with no software to install.

Whether you're working from a purchased backing track, an isolated instrument stem processed through a tool like Reaper, Moises or Lalal.ai, an audio source pulled from YouTube, or stems you've recorded yourself, this tool generates a click matched exactly to your tempo, time signature, bar length, and preferred click sound — then exports it as a WAV or MP3 ready to drop directly into your DAW, playback rig, or IEM mix.

No click should be one-size-fits-all. Some songs want a woodblock. Some want a rimshot. Some need a pure synthesized tone that cuts through stage volume without sounding musical. Some need spoken beat numbers so a drummer can count bars without second-guessing whether that sound was the click or the track. This tool gives you those options — independently configurable for accent beats and normal beats — so the click works the way you need it to, not the way it came.

Who It's For

Cover Bands

Playing live to backing tracks requires a click that's locked, correctly timed, and easy to isolate in your IEM mix. Build one for each song in the set.

Solo Artists

Running pre-recorded parts solo? Generate a custom click matched to your tracks and own your tempo feel from the downbeat of bar one.

Session & Studio Musicians

Working with stems that didn't come with a reference click? Generate one on the spot and stay locked without waiting on a producer to provide it.

Hobbyists & Home Recorders

You don't need a full DAW session to get a usable click track. Set BPM, pick your bars, hit generate. It takes less than a minute.

Drum & Instrument Teachers

Generate practice tracks at any tempo and time signature for student exercises, recorded lessons, or warm-up material.

Stem Creators

Building your own stems or producing original material? Start every session with a clean reference click that matches your production tempo exactly.

Features

Decimal BPM support — set tempos like 92.3 or 118.7 for tracks that don't sit on a round number

Seven time signatures — 2/4, 3/4, 4/4, 5/4, 6/8, 7/8, and 12/8

Per-beat pattern control — set each beat individually to Accent, Normal, or Silent

Independent sound selection — choose Woodblock, Click, Rimshot, or Spoken Voice numbers separately for accent and normal beats

WAV or MP3 export — lossless 16-bit PCM WAV for DAW use; 128 kbps MP3 where file size matters

Auto-detect BPM from audio — upload any MP3 or WAV file and the tool analyzes its tempo directly in the browser, then auto-fills the BPM and bar count fields to match the length of your track. No server involved — the audio never leaves your device.

Fine-tune slider — after BPM detection, a ±2 BPM slider lets you nudge the detected tempo in 0.05 increments before applying it, so you can dial in the exact feel without typing decimal values manually.

Fully browser-based — no installation, no account, no upload. Audio is generated and downloaded entirely on your device.

Technical

All audio rendering runs client-side using the Web Audio API via an OfflineAudioContext. The browser renders the full audio buffer in memory and exports it directly to a download — no server is involved in the generation process, and no audio data is ever transmitted or stored externally.

The Auto-Detect BPM feature also runs entirely in the browser. When you upload an audio file, it is decoded using the Web Audio API's decodeAudioData method and analyzed locally via an autocorrelation algorithm against the audio energy envelope. The file is never uploaded to any server. Once the analysis is complete the file data is discarded from memory. Detection accuracy is best on tracks with a consistent, non-drifting tempo — tracks that were recorded to a click or quantized in a DAW. Tracks with live tempo drift will return an approximate average.

Click tracks are capped at 7 minutes per export to keep browser render times practical. For longer productions, generate in segments and join them in your DAW. Output filenames created by this tool follow the format e.g.,120bpm_4-4_click.wav for easy identification after downloading it your custom click track.

MP3 encoding uses lamejs, an open-source JavaScript MP3 encoder. WAV output is 16-bit PCM mono at 44,100 Hz — compatible with every major DAW and audio playback system.
