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.

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.
