Make quiet recordings easier to hear. Import an audio or video file, or record something new, then adjust, compare and export with Increase Volume.
• Amplify files up to 3× and adjust volume precisely.
• Improve spoken audio with voice clarity, noise reduction and EQ presets.
• Compare original and enhanced playback before saving.
• Trim a section, adjust playback speed and record audio in the app.
• Create searchable transcripts and process multiple files in a batch.
• Export audio or video, save to Files, or share your result.
Increase Volume edits files you import or record. It does not increase system volume, change your speaker's hardware limits, or boost sound playing in other apps.
A Pro subscription is required for editing, processing and export. An interactive sample demo is available before subscribing. Cloud processing requires internet access; available offline tools are more limited. Features and results depend on the source recording.
Subscriptions renew automatically unless canceled in your App Store subscription settings before renewal. Any trial and price are shown before purchase.
