Audio Studio: Sound&MP3 Editor

Audio Studio is a clean, fast multi-clip audio editor for iPhone and iPad. Import songs and recordings or capture new audio with the microphone, arrange everything on a simple timeline, and export a polished track — all on your device.

EDIT WITH PRECISION
• Trim the start and end of any clip with sample-accurate handles
• Split a clip in two exactly where you need it
• Reorder clips with drag and drop
• Fade in, fade out and smooth crossfades between clips
• Per-clip volume and a master volume for the whole mix
• Full undo and redo for every edit

RECORD & IMPORT
• Record directly with the microphone, straight into your timeline
• Import MP3, M4A, WAV, AIFF, FLAC, CAF and more from the Files app
• Combine as many clips as you like into one arrangement

EFFECTS
• Speed up or slow down without changing pitch — or shift pitch on purpose
• Reverb, reverse and one-tap normalize
• Preview everything before you commit

EXPORT & SHARE
• Export your mix as M4A, WAV, ALAC, AIFF, FLAC or CAF
• Share anywhere with the standard share sheet
• Projects are regular files — back them up, copy them or move them in the Files app

MADE FOR REAL TASKS
• Tighten up a podcast episode or interview
• Clean and merge voice memos and lecture recordings
• Stitch multiple takes into a single track
• Prepare clips for videos, presentations or ringtones

PRIVATE BY DESIGN
Everything you import, record or edit stays on your device. Audio Studio collects no personal data, runs no analytics and contains no third-party SDKs. The microphone is used only while you record, and audio leaves the app only when you export or share it yourself.

SIMPLE ON PURPOSE
No timeline clutter, no subscriptions to unlock basic tools, no learning curve. Open a project, drop in your audio and get to work.
