Free Mix Analysis Tool: Loudness, Peak & Phase
Marc Aaron Jacobs
Founder, DropCue · Composer
Stop juggling a loudness meter, a spectrum analyzer, a correlation meter, and a phase scope just to know if your mix is ready. DropCue's AI Mix Analysis reads all of it in one pass, with plain-language recommendations on what to fix and how. Pro plans get 10 free analyses, and any plan can buy analysis packs that never expire (20 for $4.99).
Who this is for
You typed "free mix analysis tool" because you have a track that sounds fine in your room and you want a second opinion before you send it anywhere. Maybe it's a sync pitch, maybe it's a client deliverable, maybe it's a self-release going up on streaming next week. You don't want to install another plugin, sign up for a "free trial" that demands a card, or upload a stem to some sketchy single-purpose site that emails you a PDF and then markets to you for a year.
This page is for composers, producers, and mix engineers who already trust their ears but want the numbers to back them up. You know roughly what integrated LUFS is, you've heard "true peak" thrown around, and you've squinted at a correlation meter wondering if -0.2 is a problem (it can be). You want a fast, honest diagnostic read on a track without bouncing it out of your DAW, importing it into a metering suite, and writing the readings down by hand.
It's also for the person who is past the "is this in tune" stage and stuck on the "why does this feel small and brittle compared to a reference" stage. That gap is almost always loudness, dynamics, stereo width, and tonal balance, the exact things a mix analysis reads. You don't need a mastering engineer to tell you your low end is 4 dB hot or your sides are wider than your center. You need a tool that flags it in plain language so you can go fix it.
The audience-specific reality
Here's the quirk with "free mix analysis tool" searches: almost every result is either a single-metric widget (just LUFS, or just a spectrum) or a teaser for a paid mastering service that won't actually tell you anything until you pay. You end up opening five tabs, one for loudness, one for true peak, one for stereo correlation, one for tonal balance, and you still have to interpret all of it yourself.
Mix analysis is genuinely different from mastering, and the search intent gets muddled. Analysis is diagnostic: it tells you what's happening in the file (how loud, how peaky, how wide, how phase-coherent, how the tonal balance sits) and, ideally, what to do about it. Mastering is the fix. You should diagnose before you master, and you should absolutely diagnose before you pitch a track to a music supervisor who will A/B it against a polished commercial reference in the first three seconds.
The other thing about this audience: most of you work in files, not in a single open session. You have a folder (or a catalog) of finished and half-finished tracks, and the track you want to check is rarely the one currently open in your DAW. A real workflow tool reads the file you already have, not the one you have to re-export. That's the difference between a checkbox feature and something you'll actually use on a Tuesday night before a deadline.
And the lossy-source caveat matters here more than anywhere. If you only have an MP3 of an old track, loudness and peak readings drift from what the original WAV would show, because the encode reshaped the waveform. Honest tools flag that. A read that pretends an MP3 measures identically to the master is lying to you.
Why DropCue fits this workflow
DropCue's AI Mix Analysis is powered by ROEX, and it runs on tracks that already live in your DropCue library, so there's no export, no re-upload, no separate meter to babysit. Click a track, run the analysis, and you get one consolidated read: integrated LUFS (measured to the ITU-R BS.1770 standard), true peak including inter-sample peaks, clipping detection, stereo width, mono compatibility, phase, and tonal balance, all in the same view. Then it adds the part the standalone meters never do: plain-language AI recommendations telling you what to fix and how.
That last part is the whole point. A correlation meter showing -0.3 is a fact. "Your sides are out of phase with your center, which will collapse and lose energy when this plays in mono (phone speakers, club sums, some TV mixes), try narrowing the stereo image on the low end or checking your widener" is a recommendation. One of those you can act on tonight. DropCue gives you the second kind.
It's built in, not bolted on. You're not bouncing between your DAW, a loudness meter, a spectrum analyzer, a phase scope, and a separate "mix check" website. Your catalog is already there, and when the analysis flags something fixable, the AI Mastering engine (powered by Chosen Masters) is one click away in the same app if you want to actually fix loudness and tonal balance, not just measure it.
And on the "free" intent specifically: DropCue is honest about it. Pro plans include 10 free analyses outright. Any plan, including Starter, can buy analysis packs (20 for $4.99 or 50 for $9.99) that never expire, so you're not on a subscription clock to check a mix. No credit-card-required "free trial" that quietly bills you in 14 days. You buy a pack, the credits sit there until you use them, and you check mixes when you actually have mixes to check.
The features that matter most
✓ One-pass multi-metric read (ROEX)
Loudness, true peak, clipping, stereo width, mono compatibility, phase, and tonal balance in a single analysis instead of five separate meters and tabs. You read it once and you know.
✓ Plain-language AI recommendations
The numbers tell you what; the recommendations tell you how. Knowing your low end is hot is useless if you don't know to pull a low shelf or check your bus compression. DropCue says it in words you can act on.
✓ Integrated LUFS to ITU-R BS.1770
Streaming platforms normalize to a target loudness. Knowing your integrated LUFS against that standard tells you whether your track will get turned down (and lose perceived punch) before you ever upload it.
✓ True peak and inter-sample peak detection
A track can read under 0 dBFS on a sample peak meter and still clip on playback because of inter-sample peaks after conversion. True-peak reading catches the distortion that sneaks past a normal meter.
✓ Runs on tracks already in your library
Your catalog lives in DropCue. You analyze the file you have, no re-export from the DAW, no re-upload to a one-off website. The track you want to check is the track you click.
✓ One-click path to AI Mastering
When the analysis flags a loudness or tonal-balance problem, the Chosen Masters engine is right there in the same app to fix it, with loudness-matched A/B so you hear the change honestly instead of being fooled by it just getting louder.

Frequently asked questions
Is the mix analysis tool actually free?
Pro plans get 10 free analyses outright. Any plan, including Starter, can buy packs that never expire (20 for $4.99 or 50 for $9.99). There's no card-required trial that bills you later, and unused credits don't disappear.
What does the analysis actually measure?
Integrated loudness (LUFS to the ITU-R BS.1770 standard), true peak including inter-sample peaks, clipping, stereo width, mono compatibility, phase, and tonal balance. Then it adds plain-language AI recommendations on what to fix and how, which standalone meters don't do.
How is this different from a standalone loudness meter or spectrum analyzer?
A meter gives you one number and leaves the interpretation to you. DropCue reads loudness, peak, stereo, phase, and tonal balance in one pass and tells you in plain language what's wrong and how to fix it, all on a track that's already in your library so there's no re-export or re-upload.
Can I analyze an MP3 or a compressed file?
Yes, but be aware: for lossy or compressed sources, loudness and peak readings can drift from what the original WAV or FLAC would show, because the encode reshaped the waveform. DropCue flags these readings as approximate so you're not misled. For the most accurate read, analyze a WAV or FLAC.
Do I have to re-upload my track to analyze it?
No. AI Mix Analysis runs on tracks that already live in your DropCue library. You click the track you want to check and run the analysis, no bouncing it out of your DAW and uploading it to a separate site.
What do I do after the analysis flags a problem?
If it's a loudness or tonal-balance issue, DropCue's built-in AI Mastering (powered by Chosen Masters) is one click away in the same app, with loudness-matched before/after A/B so you judge the change honestly. For mix-stage issues like phase or stereo width, the recommendations point you back to your session with specific things to adjust.
