The biggest CueRadar update yet — a rebuilt analysis engine, a new Change Tempo tool, library-wide duplicate detection, and a batch of accuracy and compatibility fixes.
New — Sharper BPM & key detection, fully on your Mac
The beat and key analysis has been rebuilt from the ground up and now runs entirely on-device.
- More accurate BPM. Cleaner beat tracking means fewer wrong tempos and better-placed downbeats — including the orange Beat 1 marker you can nudge on the waveform.
- More accurate key detection. Camelot / Open Key results are noticeably more reliable across dance, club, and radio material.
- Faster, and offline. Analysis is quicker and needs no internet connection.
New — Change Tempo
Render a copy of any analysed track at a new BPM, one track at a time.
- Two modes. Keep pitch (Master Tempo) holds the song's key while the tempo moves; Natural moves tempo and pitch together, like riding a vinyl pitch fader.
- You choose the settings. Type the target BPM (the current BPM is prefilled but editable), pick the mode and output format (WAV, AIFF, or match the source).
- Honest quality warning. A live banner tells you how the change will sound — transparent for small nudges, with a clear "this will most likely sound bad" heads-up (and a confirm) for extreme stretches.
- Hear it first. A 10-second live preview lets you judge the result before you commit to a render.
- Your original is never touched. The new file is written next to it as
… (125 BPM).wav, with conflict-safe naming.
Open it by right-clicking a track → Change Tempo…, or from the inspector.
New — Find duplicates across your whole library
The Duplicate Finder now automatically includes every folder you've already scanned in Music Analyser — no need to add them twice.
- Library-wide, zero extra steps. Switch to Duplicate Finder and your whole scanned library is already there.
- Count badge at a glance. A red badge on the Duplicate Finder tab shows how many redundant files you have, visible from any tab.
- Inline markers in Music Analyser. Tracks that have copies show a small duplicate indicator in the list — click it to jump straight to that group.
- Smart about versions. Remixes, edits, and bootlegs of the same song are no longer mistaken for duplicates of each other. CueRadar reads the version from the filename — even a bare producer name like
(Blasterjaxx), no keyword list needed — and won't group files of clearly different length.
- Opt folders out. Exclude any folder from duplicate scanning without removing it from Music Analyser.
New — Quick ½ / ×2 BPM correction
When the analyser double- or half-counts the tempo, fix it in one click — from the track's right-click menu or the ½ / ×2 buttons in the inspector. The corrected BPM (and its beat grid) is saved immediately; no re-analysis needed.
Fixed & improved — device compatibility
The "playable on your gear" check is more honest and accurate.
- Pick your own gear. On a fresh install CueRadar no longer assumes a lowest-common-denominator device — choose your decks in Settings and everything is checked against exactly what you own.
- FLAC files no longer mislabeled "Unsupported." CueRadar now reads FLAC bit depth directly from the file, so a healthy lossless track isn't failed just because macOS wouldn't report its bit depth.
- 32 kHz MP3s play. Standard 32 kHz files are no longer wrongly flagged — they're supported across modern Pioneer and Denon gear.
- 32-bit WAV/AIFF is a gentle note, not a hard error. Modern Pioneer hardware plays 32-bit float fine, so CueRadar shows an "off-spec" advisory instead of "not playable." Older gear that genuinely can't play it still shows the blocking warning.
Notes
- WAV/AIFF tempo output carries the new BPM in its filename; embedded BPM tags are written for MP3/M4A/FLAC outputs.
- The duplicate badge updates automatically as you scan, and clears when duplicates are resolved.
- BPM ½/×2 corrections are reflected immediately in the track list and any open inspector.
