Микс-анализатор

An overall mix quality score (Surgical, Smooth, Dynamic, Raw, or Chaotic), per-transition scores covering timing accuracy, harmonic compatibility, and energy flow, plus a waveform timeline with clickable transition pins. Filter between highlights and issues to focus on what matters.

Sub-second accuracy on most electronic music. The analyzer detects transitions in full 120-minute mixes, identifying where each track blends into the next — including long, gradual transitions that simpler tools miss.

Five genre profiles: Rominimal, Techno, House, Drum & Bass, and Trance. Each profile calibrates scoring weights differently — a 32-bar blend scores well in Rominimal but would penalize a DnB set where fast cuts are expected. Auto-detect picks the best profile.

Yes. Each transition is scored on key compatibility using the Camelot system. The report shows which transitions are harmonically matched and which clash — so you can identify the exact moments that need reworking.

BPM is one dimension. The mix analyzer evaluates the full picture — whether transitions are timed correctly, whether keys are compatible, whether energy builds and releases in a coherent arc, and whether the overall flow tells a story. It's the difference between a metronome and a music teacher.

No. The full analysis pipeline runs directly on your device. A 120-minute mix stays on your machine — no upload, no waiting for server processing, no file size restrictions.

A DJ mix is a single audio file containing multiple tracks blended together. The analyzer's job is to find where each track ends and the next begins, then evaluate how well the transition worked. This breaks into three DSP stages.

Transition boundary detection

The analyzer computes spectral flux — the per-frame change in frequency content — across the full mix. Sharp flux spikes mark moments where the spectral content shifts significantly, which usually corresponds to a new track entering or leaving. The analyzer then cross-references flux spikes with energy envelope discontinuities (sudden RMS shifts) and tempo grid breaks (BPM deltas above a threshold). When two of those three signals align within a one-second window, that timestamp is locked as a transition boundary.

Per-transition scoring

Each detected transition gets three independent scores. Timing accuracy measures how cleanly the outgoing track's last downbeat aligns with the incoming track's first downbeat — a one-beat offset penalizes more than a four-beat offset because it sounds dragging rather than intentional. Harmonic compatibility uses the Camelot wheel — same code (8A → 8A) scores perfect, adjacent codes (8A → 7A or 9A) score high, jumps of three or more positions score low. Energy flow tracks RMS over a 30-second window before and after the transition to detect whether energy built up, dropped, or stayed flat.

Overall mix score

The five quality buckets (Surgical, Smooth, Dynamic, Raw, Chaotic) come from genre-calibrated weights applied to the per-transition scores. A Rominimal set rewards long 32-bar blends and gradual energy curves; a Drum & Bass set rewards fast cuts and rapid energy swings. Auto-detect uses the dominant BPM range and rhythmic pattern to pick the right profile. Use BPM Finder or Поиск ключей first if you only need single-track BPM or key data instead of a full mix evaluation.

The waveform timeline shows clickable pins at each detected transition. Pin color encodes the overall transition score: green = clean (timing, harmony, and energy all aligned), yellow = workable but one dimension is off, red = clash (key incompatibility, off-beat alignment, or jarring energy drop). Click any pin to expand the per-transition detail view — it shows the exact BPM delta, the Camelot key transition, and the energy envelope around the cut.

Common clash patterns and what they mean

• Red pin with green energy, red harmony — keys clash but energy flow is intentional. Common when DJs prioritize crowd energy over technical mixing. Acceptable in peak-time sets, not in long-form melodic journeys.
• Yellow pin with off-beat timing — one-bar drift, often from manual beatmatching without sync. Use the timing offset readout to fix it on the next attempt.
• Red pin with sudden RMS drop — a flubbed transition where the outgoing track ended before the incoming track was loud enough. Fix by extending the outgoing fade or starting the incoming track earlier.
• Green pin during a fast cut — the analyzer recognized the cut as intentional because the energy envelope matched the genre profile. DnB sets get many of these; Rominimal sets get almost none.

Use the Highlights filter to focus only on green pins (the moments worth replaying or sampling), or Issues to surface only yellow and red pins (the ones to study and improve). For deeper context on the harmonic clash patterns, the Chord Detector can analyze individual tracks to verify the Camelot codes the mix analyzer used.
