Four Ways to Detect BPM

Upload one or many audio files, tap along to a beat manually, or use real-time microphone analysis to detect BPM instantly. All modes run entirely in your browser.

Flexible BPM detection for any workflow

Analyze Up to 50 Files at Once

Drag and drop multiple audio files (MP3, WAV, FLAC, AAC, OGG, M4A) up to 50MB each. The tool processes them together, saving hours of prep time for DJs and producers.

Efficient bulk tempo analysis

100% Browser-Side Processing

Audio files are decoded and analyzed locally using the Web Audio API and ONNX Runtime Web. Zero server uploads means your tracks never leave your device.

Complete audio privacy and security

Benchmark-Proven Detection

BPM Finder achieves a 74% win rate vs Tunebat v6 in head-to-head testing, with 69% Hit4 accuracy (within ±4% of true BPM) across 300+ sealed benchmark tracks.

Industry-leading BPM detection precision

Fast Preview and Full Analysis

A fast preview detector estimates BPM in under 500ms before the full DeepRhythm CNN analysis runs. The complete pipeline includes decoding, rhythm feature extraction, and octave error resolution.

Quick results without sacrificing accuracy

Confidence Scoring and Export

Each result includes a confidence score, and you can export your findings without creating an account. The tool also cross-checks candidate tempos to reduce half-time and double-time errors.

Reliable, actionable BPM data

• 74% Win Rate vs Tunebat in Sealed BenchmarkBPM Finder reports a 74% win rate against Tunebat v6 in a head-to-head benchmark across 300+ sealed tracks, with a +/-4% hit window. The benchmark ledger is reproducible and includes tracks from GiantSteps, Incompetech, and challenge sets.
• 100% Browser-Side ProcessingAll audio processing happens locally in your browser using the Web Audio API, Essentia.js, and an ONNX Runtime Web model. No audio files are uploaded to servers, ensuring privacy and zero server load.
• Multiple Analysis ModesBPM Finder offers four modes: single file upload, batch processing (up to 50 files, max 50 MB each), real-time microphone analysis, and manual tap tempo. It supports MP3, WAV, FLAC, AAC, OGG, and M4A formats.
• Fast Preview and Octave Error ReductionThe tool provides a fast preview BPM estimate in under 500ms before full CNN analysis, and uses onset-weighted tatum matching to reduce half-time and double-time errors, improving accuracy.

• Pricing Page Contains Unrelated SaaS ProductThe /pricing page lists plans for 'ShipAny', an AI SaaS startup boilerplate, with prices like $99/month for Starter. These are not BPM Finder features or pricing. BPM Finder itself is free to use, and no pricing for BPM Finder is shown.
• Speed Claims Are QualifiedWhile BPM Finder claims fast preview (<500ms) and v6 median analysis timing, it explicitly states it does not claim to be the fastest overall because Tunebat still has a small P95 latency edge in the v5 benchmark.
• Benchmark Accuracy is Not PerfectThe 74% win rate and 69% Hit4 accuracy are based on a specific benchmark with a +/-4% hit window. This means about 26% of tracks may not match Tunebat's result, and 31% may fall outside the 4% tolerance.
• No Integration or Certification ClaimsThe website does not mention any integrations with DAWs, streaming services, or other tools. It also does not claim any certifications or official partnerships. The only external tools referenced are Essentia.js and ONNX Runtime Web, which are open-source libraries.

Fast remix preparation

A DJ can paste a YouTube link, get the exact BPM instantly, and align it with their set, shaving minutes off the preparation phase. The tool’s DAW plugins let the tempo be imported directly into Ableton Live, keeping the workflow seamless.

Metadata enrichment for libraries

Music libraries upload batches of tracks and receive a CSV with BPM, enabling better search filters and licensing matches.

AI‑generated music alignment

When using AI Music Maker to create a melody, BPM Finder ensures the generated piece matches the target tempo of an existing track, preventing sync issues.

Fitness video production

Content creators pull the BPM of a track to program workout intervals, guaranteeing that visual cues line up with the music’s beat.
