How it works
Two analysis modes. One system.
LoopBounce analyzes different stages of the production process. Use Master Check to evaluate a finished master before release. Use Mix Check to identify problems in a mix before mastering.
Master Check
How it works
A professional analysis system
for finished masters.
LoopBounce evaluates a finished master through a structured technical framework. It does not generate, process, or automatically master audio — it examines your track across loudness, dynamics, tonal balance, stereo image, and phase behavior, then returns clear feedback to guide revision and decision-making.
The distinction
Not mastering. Analysis.
What LoopBounce is not
- An AI mastering engine
- An automatic audio enhancer
- A one-click fixer
- A replacement for artistic judgment
What LoopBounce is
- A structured analysis framework
- A decision-support layer
- A second opinion, grounded in reference data
- A way to identify strengths, risks, and revision priorities
The analysis reads the master. It does not rewrite it. Every creative decision stays with you.
What it analyzes
Five dimensions of a finished master.
Every master is evaluated across the same five technical dimensions — the same framework real mastering engineers use when reviewing a release.
Loudness discipline
Integrated LUFS, true peak, and headroom evaluated against club delivery standards — not streaming averages.
Dynamic integrity
LRA, crest factor, and transient preservation — checking that the master still breathes without being crushed.
Tonal control
Spectrum shape across six frequency bands, compared to a calibrated genre envelope to flag recessions or build-ups.
Stereo image
Width, balance, and side-signal energy across the frequency range — so the mix translates from headphones to a PA.
Phase coherence
Correlation across frequency bands and worst-moment detection — mono compatibility for every playback system.
Global stability
All five dimensions feed a single Quality Score — a calibrated reference-suitability measurement rather than a subjective rating.
How the analysis works
From audio to structured feedback.
The pipeline is deterministic, reproducible, and mastering-engineer readable. No generative layer, no black box.
Measure
Every audio file is decoded and passed through measurement modules — loudness (EBU R128), dynamics (LRA, crest factor, RMS), spectrum analysis (FFT across the full song), stereo width, and per-band phase coherence.
Compare
Raw measurements are compared to a calibrated reference model — a curated envelope built from real-world club music masters across techno, melodic techno, and dark electronic genres.
Interpret
Cross-factor rules translate measurements into findings — sub recession tied to spectrum data, phase exposure linked to worst-moment timestamps, loudness flagged against club-delivery standards.
Report
The interpretation becomes a structured report — a Quality Score, per-dimension breakdown, a tonal envelope chart, strengths, risks, and actionable revision guidance written in mastering-engineer language.
The reference model
Calibrated against real club masters.
A number means nothing without context. LoopBounce evaluates every master against a curated reference envelope — built from real, approved club music masters across techno, melodic techno, and dark electronic genres.
This is not a streaming-loudness target or a generic EQ curve. It's a multidimensional envelope that captures how professional club masters actually behave — their loudness ceiling, their spectrum shape, their dynamic headroom, their stereo behavior.
When your master is analyzed, the system evaluates whether each dimension sits within, above, or outside the expected range. That's where the feedback comes from — not from arbitrary thresholds, but from how your track compares to the real world.
Tonal envelope
Your master vs. genre reference
What you receive
A structured report you can act on.
Quality Score
A calibrated 0–100 reference-suitability score, broken down across five weighted dimensions.
Technical metrics
LUFS, True Peak, LRA, Crest Factor, RMS, Peak, Balance — each classified against club-delivery targets.
Tonal report
Full-track spectrum analyzer with peak overlay, per-band frequency deltas vs. the genre target curve.
Stereo coherence review
Phase behavior across frequency bands, with worst-moment timestamps and mono-compatibility assessment.
Strengths & risks
Structured written findings — what's working, what to review, and why it matters for the release.
Revision guidance
Optional plugin-specific suggestions (e.g., iZotope Ozone module recommendations) that stay out of the way until requested.
Who it's for
Built for people who ship music.
Mastering engineers
A calibrated second opinion before approving a final master. Catch an overlooked sub recession or a phase issue before the label does.
Producers & artists
Compare revisions side-by-side with objective data. Know whether the version you're about to send is actually better than the one before it.
Labels & A&Rs
Review incoming masters against a reference framework built from real club music. Make technical go/no-go decisions with confidence.

Analyze a trackMix Check
How it works
Know if your mix is ready for mastering.
LoopBounce analyzes your mix before mastering, focusing on low-end control, dynamics, stereo depth, tonal balance, and arrangement flow. The goal is to show what is working, what is wrong, and what should be fixed before the track goes to mastering.
The distinction
Not mastering. Mix analysis.
What it is not
- Not automatic mastering
- Not a loudness maximizer
- Not a generic AI music tool
- Not a replacement for a mixing engineer
What it is
- A structured mix analysis tool
- A system to detect technical and musical mix problems
- A pre-master quality check for club music
- A way to understand what to fix before mastering
Mix Check does not master your song. It helps you understand whether the mix is technically and structurally ready to be mastered.
What Mix Check analyzes
What Mix Check analyzes
Mix Check evaluates the mix across five dimensions that matter before mastering. Each one is designed to reflect how the track will behave on real club systems and whether the mix is ready for the mastering stage.
Low-End Control
Checks the relationship between sub, kick, upper bass, mono stability, and low-end consistency. The goal is to avoid weak translation, buried kick, muddy bass, or low-end phase issues.
Dynamics & Punch
Measures headroom, loudness range, crest factor, transient behavior, and section contrast. This shows whether the mix still has movement and impact, or if it is already over-compressed before mastering.
Balance & Clarity
Evaluates tonal balance, boxiness, midrange strength, harshness, air, resonances, and spectral crowding. The goal is to identify where the mix feels balanced, congested, dull, or fatiguing.
Stereo & Depth
Checks stereo width, mono compatibility, center stability, phase coherence, spatial overload, and depth behavior. This shows whether the mix feels wide and controlled or unstable and risky in mono.
Arrangement Energy & Flow
Analyzes builds, drops, breakdown contrast, section consistency, transitions, and rhythmic anchor. This helps detect whether the track works over time, not just in a static frequency snapshot.
How the analysis works
From upload to actionable feedback
Mix Check follows the same structured logic as Master Check, but it focuses on readiness before the mastering stage.
Upload
Upload your mix in WAV, FLAC, or AIFF format.
Analyze
LoopBounce evaluates the low end, dynamics, tonal balance, stereo behavior, and arrangement structure of your mix.
Feedback
Receive direct, structured feedback about what is ready and what needs attention before mastering.
Fix
Use the findings to improve the mix before sending it to a mastering engineer.
The reference model
Built against real mix references
Mix Check is not based on abstract technical targets alone. Its scoring logic is calibrated against approved pre-master mixes in club-oriented electronic music, so the feedback reflects real-world mix behavior rather than generic audio theory.
The purpose is not to force every mix into one identical shape, but to identify where your mix moves too far away from a usable and professional pre-master range.
Mix reference profile
Your mix vs. approved pre-master range

Dimension breakdown
Each of the five dimensions is scored independently so you can see exactly where the mix is weak.
Diagnostic insights
Cross-factor findings explain hidden problems that single metrics alone would not reveal.
