Audio Editor - Music Booster for iPhone

App summary for iPhone users

Audio Editor — Music Booster is a free iOS audio workstation built for iPhone owners who need quick, hands-on sound editing. The interface focuses on an intuitive timeline and project-based workflow so you can open, work on, and save sessions without hassle. It supports importing from multiple sources and is suitable for hobbyists and pros alike.

Core capabilities

• Rapidly save and reopen projects while working directly on a timeline for seamless session management.
• Import and merge multiple audio files from sources such as the iTunes library and voice memos.
• Work on several tracks at once with multitrack mixing and arrangement tools.
• Perform standard edits — cut, copy, paste and remove portions of audio — using touch-friendly controls.
• Make frame-accurate changes using either a waveform view or a multitrack editor for precise segment selection.
• Zoom in/out of the timeline and organize tracks to keep complex sessions manageable.

Sound-shaping tools and outputs

• A selection of effects including equalization, distortion, and reverberation to polish or radically alter sounds.
• Built-in utilities for producing short audio assets like ringtones and jingles for personal or promotional use.
• Tools aimed at both subtle mastering and creative sound design, letting you refine mixes or experiment freely.

User experience and workflow notes

The app emphasizes simplicity: drag-and-drop style arranging, timeline scrubbing, and clear project navigation reduce friction during editing. Whether assembling a quick ringtone or refining a multitrack mix, the controls are designed to let you focus on the audio rather than the mechanics.

Alternative recommendation

Ninety-Nine X Free is a recommended alternative if you’re exploring other options. It offers a different set of features and a distinct workflow that may better match certain editing styles or preferences.
