Vivaldi Audio Editor
A professional audio editor with an innovative marker-based workflow. Cut, clip, filter, and export your recordings with offline rendering and a stunning steampunk interface.
Key Features
A new approach to audio editing on mobile.
Interactive Waveform
Scrollable, zoomable (1x-16x) waveform visualization with Canvas-based rendering. Pinch to zoom, drag to scroll. A fixed playhead at the center keeps you oriented.
Marker System
Place markers anywhere on the waveform during playback or manually. Auto-labeled A-Z. Drag to reposition, long-press to delete. Up to 26 markers per recording.
Range Operations
Select any two markers to define a range, then Cut (remove from output) or Clip (export as separate file). Visual overlays show operations in real-time.
Audio Filters
7 professional filters: EQ (per-instrument presets), Compressor, Noise Gate, Limiter, Reverb, Delay, and Time Pitch (speed + transpose).
Offline Rendering
All processing happens offline using Apple's AVAudioEngine. Non-destructive workflow — your original file is never modified.
Smart Export
Export the edited main file plus any clipped segments as separate M4A files. Share via any iOS share sheet.
Professional Audio Filters
Built on Apple's AVAudioUnit framework. Studio quality, zero third-party dependencies.

How It Works
Load
Open any audio file from your recordings or Files app. The waveform loads instantly.
Mark
Place markers at key points — section breaks, mistakes, highlights. Markers auto-label A through Z.

Export
Render and export. Your edited file + any clips export as separate M4A files.
