Measured on six things

Identify songs in your browser from uploaded audio files, media URLs, or live recordings without creating an account.

Speed

Lighthouse mobile 43/100 with LCP 16.1s and FCP 11.8s; desktop 86/100. The mobile gap points to a heavy client bundle, consistent with in-browser audio processing.

Song Finder

About this app

Song Finder is an online song-recognition tool that works with several kinds of audio input. Users can upload an audio file, provide a media URL, or make a live recording in the browser and use it to identify a track. The focused workflow is useful when a song appears in a saved clip, online video, or nearby recording and the title or artist is unknown.

Key features

1Song recognition from uploaded file, pasted media URL, or live browser recording — no account required.
2Multi-engine recognition chain that tries up to three fingerprint databases in sequence.
3BPM, key and Camelot code lookup plus a DJ Set Generator for harmonic mixing order.
4Local browser audio tools: EQ, speed and pitch correction, trimmer, merger, normalizer, noise reduction.
5Lyric Finder and Mood Finder for when you have a line or a feeling but no audio.

Scout Review

Written by AI from measured evidence, scored out of 100.

Song Finder is a free, no-signup song identification tool that also bundles a serious set of audio analysis utilities — BPM and key detection, Camelot codes, speed and pitch correction, EQ, trimming and a DJ set generator. The recognition flow is clean and the copy is specific rather than generic. It is held back by a slow mobile page (43/100, 16.1s LCP), thin security headers (4/12) and a sprawling tool list that dilutes the core promise. Accessibility is genuinely strong at 96/100. For DJs and content creators dealing with modified audio, the analysis tools are the reason to be here; for casual listeners, Shazam is faster and already on the phone.

Measure by measure

Usability

No sign-up, one-screen upload/URL/record flow, plus a how-it-works explainer and recognition tips. Tool sprawl across 20+ pages is the main friction; no unified workspace shown.

Design

Dense but coherent tool-hub layout with consistent naming and a clear primary upload/record panel. Copy is specific and confident; visual polish unverified without a rendered audit.

Speed

Lighthouse mobile 43/100 with LCP 16.1s and FCP 11.8s; desktop 86/100. The mobile gap points to a heavy client bundle, consistent with in-browser audio processing.

Security

HTTPS enforced with SPF and DMARC, but no HSTS, CSP, frame protection or Referrer-Policy — 4/12 header checklist. No published audits or security page found.

Accessibility

Lighthouse accessibility 96/100 with only contrast and accessible-name mismatches failing. Language switcher and theme toggle present; no WCAG statement published.

Growth

Real problem with a real wedge — BPM/key/Camelot analysis and speed-pitch correction for DJs and creators that Shazam, AHA and SoundHound don't offer. Recognition itself is a free-default fight.

Improvement areas

Mobile performance: 43/100 Lighthouse with 16.1s LCP and 11.8s FCP.
Security headers: no HSTS, CSP, frame protection, Referrer-Policy or Permissions-Policy (4/12).
Navigation sprawl: 20+ tools with no unified workspace or clear entry path per user type.
Accessibility polish: failing contrast ratios and visible labels not matching accessible names.

Design & Usability

Song Finder's homepage is a tool catalogue wearing a search box. The primary panel — upload, paste URL, or record — is exactly right for the job, and the 'no account, no email, no credit card' promise is stated before anything else. The how-it-works strip and the four recognition tips (start with the raw clip, pick the melodic segment, fix one problem at a time) are unusually practical for a free tool. The problem is scope: the nav lists over twenty tools from Lyric Finder to Audio to MIDI to DJ Set Generator, and nothing on the page shows how they connect into one workspace. A casual listener looking for a title has to ignore a lot of producer furniture to find the one box they need.

Speed & Security

Speed is the weak spot. Lighthouse mobile scores 43/100 with a 16.1s largest contentful paint and 11.8s first contentful paint, while desktop scores 86/100 — a gap that points at a heavy client-side bundle, which makes sense given the site claims audio editing and analysis run locally in the browser. On a phone, that is a long wait for a tool whose whole value is immediacy. Security is middling: HTTPS is enforced and SPF/DMARC are configured, but HSTS, CSP, frame protection, Referrer-Policy and Permissions-Policy are all missing, giving 4/12 on the header checklist. No SOC 2, ISO, security page or bug bounty was found. The 'Privacy First' and local-processing claims are reasonable, but they are marketing copy, not a published policy.

Accessibility & Growth

Accessibility is the strongest measured dimension: 96/100 on Lighthouse, with only two failing audits — insufficient color contrast and visible text labels that don't match their accessible names. A language switcher and theme toggle are present, though no WCAG statement is published. Growth is a judgement on the idea. The problem is real and the wedge is specific: BPM, key, Camelot codes, speed-and-pitch correction and harmonic set building are things Shazam, AHA Music and SoundHound simply don't do, and the sped-up-TikTok use case is a genuine modern pain. The limit is that the core recognition feature competes with free defaults everyone already has installed, so the differentiated tools have to carry the product. The domain is only months old, so there is no traction to read.

Conclusion

Worth a bookmark if you regularly wrestle with sped-up clips, remixes or set building — the local analysis tools are the differentiator and they cost nothing. If you just want a title from the radio, the mobile load time alone will send you back to the app you already have. The fastest win available to the maker is performance: fix the mobile bundle and this becomes a much easier recommendation.

Suggestions for improvement

Cut the mobile bundle: 16.1s LCP is the single biggest conversion killer on the site.
Add HSTS, CSP, X-Content-Type-Options and Referrer-Policy — cheap headers, real signal.
Fix the two failing a11y audits: contrast ratios and accessible names on labelled controls.
Surface the DJ/creator tools as a separate landing path instead of burying them in a 20-item nav.
