Read full description

QuickHumming is a melody capture and MIDI review studio designed for iOS and macOS. QuickHumming captures an idea quickly, preserves the Original Audio first, and makes detected MIDI a reviewable proposal rather than an automatic replacement. KEY FEATURES: - Three capture modes: Record Humming or enter notes with Keys and Pads. - On-device pitch analysis: Convert a monophonic voice or whistle into detected note candidates without uploading audio. - Honest review: Compare Original and detected timing, inspect confidence, edit notes, and approve only what sounds right. - Non-destructive correction: Trim, timing, pitch, sound, and volume remain project settings instead of replacing the recording. - Takes and recovery: New recordings become new takes and interrupted work remains available for review. - Share and continue: Export audio or MIDI, archive the draft, or open a copy in QuickTrack. PERFECT FOR: - Capturing a melody before it is forgotten - Turning a single hummed or whistled line into editable MIDI - Entering ideas with an on-screen keyboard or pads - Continuing a reviewed melody in QuickTrack GETTING STARTED: - Choose Humming, Keys, or Pads. - Record one take and stop when the idea is safely captured. - Review uncertain notes and compare Before with After. - Approve the candidate or continue editing timing and pitch non-destructively. - Export audio or MIDI, archive the draft, or open a copy in QuickTrack. PRIVACY & SECURITY: - Original Audio is saved first as WAV and is never replaced by analysis. - Pitch analysis runs on-device without uploading music. - Corrections are non-destructive project settings. - Recovery preserves interrupted or partially finalized takes for review. FREE AND PRO: - Start with a seven-day ad-free trial. - Free keeps the full feature set and may show mobile advertising or a daily desktop support reminder. - QuickHumming Pro removes ads and reminders through a yearly subscription or a one-time lifetime purchase.
