Noise Reducer

Make every word clearer.

Help with cleaning speech in your audio and video recordings.

Contact hello@erised.io. Include your iPhone model, iOS version and what happened. Please don’t send private recordings unless we agree that a sample is needed.

How do I clean a recording?

Open Clean, choose a video from Photos or a file from Files, then tap Clean recording. Compare Original and Cleaned before saving. Use Trim to select a section first. Drag an edge, then hold it still briefly to zoom in for finer adjustment. Selected audio is uploaded through Cloudflare to ElevenLabs; video images stay on your phone.

What is free, and what does Pro include?

Free includes 30 seconds total across your recordings. New imports start with up to 30 seconds selected. Pro includes 20 minutes per monthly subscription period, with no rollover. Settings shows your remaining allowance. The bundled sample uses a pre-cleaned result and never spends allowance. Prices appear before purchase.

Where is my result saved?

Completed cleanups appear in History. Reopen them to compare or share again. Save audio as WAV, or video as MOV with its cleaned soundtrack. You can also export just the audio from a video. Deleting a History item removes the app’s copies, not files already exported elsewhere.

Why did cleaning stop?

Keep the app open and connected while cleaning. If interrupted, reopen the same recording with the same trim range to retrieve the existing result, available from our service for up to 24 hours. Uncertain requests are not automatically sent again. Your original is preserved. If storage is low, free up space or trim a shorter clip.

Can I reduce more noise?

Cleanup uses cloud voice isolation. There is no strength setting. Compare Original and Cleaned before saving; badly damaged audio may still sound unnatural.

Which recordings work best?

The app is designed for speech. Heavy distortion, wind striking a microphone, strong echo or overlapping voices may not be recoverable. Listen to the free result before buying. Output audio is mono; video export may re-encode the picture. Files need an audio track and a format that iOS can decode.

How do I restore or cancel Pro?

Use Settings → Restore purchases with the Apple Account used to subscribe. Manage or cancel through Settings → Manage subscription, or your iPhone’s Settings → your name → Subscriptions. Cancellation doesn’t remove saved recordings.

Can I change the appearance?

Open Settings → Appearance → Theme and choose System, Light or Dark.
