TuneLens evaluates your track across five scored dimensions, examining both the technical characteristics and creative factors that determine how a song performs in the real world. Each dimension gets a numerical score, a written assessment, and specific time-coded observations — not a vague summary, but a structured report you can act on. The goal isn't a grade; it's a clear picture of where your track is strong and where it's losing ground.
Sync Appeal
Commercial fit, emotional arc, and placement potential. The AI assesses how well the track would serve TV, film, advertising, and trailer contexts — including whether the structure, energy, and mood match the kinds of cues that actually get placed.
Production & Sound Design
Arrangement quality, texture, instrumentation choices, and how well the production supports the song's emotional intent. Covers density, contrast between sections, and whether the sonic palette feels cohesive or scattered.
Mix
Frequency balance, stereo width, dynamic range, low-end control, and separation between elements. The AI flags frequency clashes, overly crowded arrangements, and moments where the mix is working against the song rather than for it.
Mastering
Loudness levels, limiting, transient handling, and final output quality relative to commercial standards and streaming platform targets. The report identifies whether the master is hitting appropriate LUFS targets and how it compares to released material in the same genre.
Songwriting
Structure, hook strength, lyrical clarity, and the relationship between the music and the words. The AI assesses whether the arrangement supports the lyrical narrative, whether the hooks land at the right moments, and how the song's internal logic holds together from intro to outro.
How it works
-
Upload your track
Drop an MP3, WAV, or audio file. TuneLens runs the AI analysis immediately — no configuration, no setup, no template to fill out. The analysis starts as soon as your file is processed.
-
Read the scored report
Five scored sections, each with a written assessment, specific strengths and weaknesses, and time-coded observations flagging exactly where issues occur. Every score is explained — you'll understand why the AI landed where it did, not just what the number is.
-
Work through action items
A consolidated, prioritized list tells you what to fix first — ranked by impact so you're not guessing where to spend your time. Re-upload revised versions and track your score progress over each iteration.
More than a score
A score on its own tells you very little. An 71 in Mix means nothing unless you know which frequencies are causing the problem, which elements are stepping on each other, and what a fix would actually look like. That's the difference between TuneLens and a meter plugin: the score is just the headline. The action items are the report. Every issue the AI surfaces comes with enough context that you can take it back to your session and do something about it without guessing.
TuneLens also supports reference comparison. Upload a commercially placed track alongside yours and the AI runs a side-by-side assessment — showing you exactly where the gap exists between your version and a track that's already been placed. This is particularly useful for producers working toward sync, where the brief often names a reference track and you need to understand in concrete terms how far your production sits from it across mix, mastering, energy, and mood.
Every revision you upload is saved and scored, so you can see whether your changes actually moved the needle. It's common to make what feels like a significant improvement in a session and find the score hasn't shifted — or to make what feels like a small tweak and watch a problem dimension jump several points. Version tracking makes that feedback loop visible and removes the guesswork from the revision process.
Frequently asked questions
What is an AI song analyzer?
An AI song analyzer is a tool that listens to your track and returns a detailed assessment of its strengths and weaknesses across production, mix, mastering, and commercial appeal. TuneLens analyzes uploaded MP3s and scores each dimension, then generates prioritized action items so you know exactly what to fix first.
What does TuneLens analyze in a song?
TuneLens scores five dimensions: Sync Appeal (commercial fit and placement potential), Production & Sound Design (arrangement, texture, instrumentation), Mix (frequency balance, stereo width, dynamic range), Mastering (loudness, limiting, final output), and Songwriting (structure, hooks, lyrical fit). Each section includes a detailed written assessment and time-coded observations.
How accurate is AI song analysis?
AI song analysis is highly consistent for technical dimensions like mix and mastering — frequency balance, loudness levels, stereo width, and dynamic range are measurable characteristics the AI scores reliably. For subjective dimensions like sync appeal and songwriting, the AI draws on patterns from commercially placed tracks. It gives you a clear starting point and concrete things to investigate, not a final verdict.
Is TuneLens free to use?
Yes. The Free plan gives you 2 analysis credits per month with no credit card required. Each credit runs one AI song analysis. Paid plans start at $4.99/month for more credits and access to the reference comparison and sync brief matching features.
