The TuneLens Feature Set

Track Analysis

What it is: TuneLens's core analysis engine. Upload an MP3 and it scores the track across five dimensions (Sync Appeal, Production & Sound Design, Mix, Mastering, and Songwriting), each with a written assessment, time-coded observations, and a consolidated, prioritized list of action items.

How it runs: Fast mode (1 credit) for quick feedback, or Deep mode (2 credits) for a multi-phase audit that adds section-level action items. Worth it for anything you're about to pitch. See the AI song analyzer →

Cue Score

What it is: TuneLens's sync-readiness score: a single number that summarizes how ready a track is to pitch to a music supervisor, built from the Track Analysis assessment. It never arrives naked: the score comes with its reasoning and an ordered fix list.

Why it matters: it turns "I think this might be ready" into a concrete, comparable measure you can improve revision over revision. What "sync-ready" means →

Brief Checker

What it is: TuneLens's music-supervisor brief decoder. Paste a brief and it returns structured targets (mood keywords, genres, tempo range, production style, instrumentation, reference artists, and an explicit "avoid" list), then matches up to three of your tracks against it with a per-track pitch verdict you can export as a PDF.

Also called: a sync match or sync matching tool — the phrasing common in sync communities for AI that matches music to a brief. Brief Checker is TuneLens's name for it, run maker-side rather than catalog-side.

Why it matters: it removes the optimism bias that makes makers pitch off-brief. Decode a brief →

Reference Check

What it is: TuneLens's reference-comparison feature. A/B your track against a commercially placed reference and get side-by-side scores, an A/B spectral overlay with AI-flagged problem frequencies, a stereo-width comparison, and a written audit with quick-fix recommendations.

Why it matters: it level-matches first, so you compare the mix, not just which file is louder. Run a Reference Check →

Song/Demo Mode

What it is: TuneLens's songwriter-focused analysis mode (1 credit). It evaluates song structure, section phrasing, hook strength, and vocal key, and ends with a production-readiness verdict: Ready for production, Ready with caveats, or Needs work.

Why it matters: it tells you whether to keep writing or start producing, using a second opinion that can actually hear the track. Get song & demo feedback →

Sync Pitch Tracker

What it is: TuneLens's built-in CRM for sync pitching. Log pitch submissions, track relationship status with supervisors and agencies (Cold → Warm → Hot → Agreement), record signed songs and placements, and add dated communication notes to any contact.

What it is not: a fan-marketing CRM. It tracks the placement side of the business (supervisors and pitches), not your listener base. See the pitch tracker →

Free supporting tools

Alongside the AI features, TuneLens publishes a set of free, no-signup audio tools you can run in the browser: a LUFS / loudness meter, a BPM & key finder, a stereo & phase checker, and a dynamic range meter. They cover the technical checks that feed into a sync-ready master.
