Loop your own audio on iPhone with NOYZ: 5 simple steps
To play a familiar recording on repeat, save it in Files, import it into NOYZ, then trim and adjust the loop before choosing a timer. That could be your own fan, rain at home or another sound you are entitled to use.
I’m Paul Calver, NOYZ’s developer. This guide describes the released iPhone app. NOYZ requires iOS 26 or later and Pro for playback; you can hear short samples before choosing Yearly or Lifetime. Support explains the plans and restoring access.
1. Get the recording into Files
Start with an audio file you already have, or make a recording in a recording app and save or export it to Files. NOYZ imports audio; these steps do not mean NOYZ records through the microphone itself.
Pick a short, representative section with a steady sound. A sudden voice or a door shutting may be exactly what you do not want repeating. If the file is stored in a cloud service, make it available on your iPhone before you need offline playback.
Keep the original somewhere you control. Importing a copy into an app is useful for listening, but it is not your separate backup.
2. Import it into NOYZ
Open NOYZ’s sound library, choose the audio import option and select the file through Files. Keep NOYZ open until the import finishes before choosing another sound.
NOYZ copies the imported recording onto your iPhone and does not upload it. The source file remains subject to its original storage provider. The privacy policy explains that distinction and the app’s separate purchase and analytics processing.
If importing fails, check that the original is fully downloaded and try an audio file the picker accepts. Use NOYZ support if you need help; avoid attaching private recordings unless they are needed for your specific question.
3. Trim and listen to the join
Use the recording controls to trim the beginning and end, then adjust the loop and crossfade. Listen through the point where the recording starts again. A good join for your recording may need a different trim from the one that looks neat on screen.
Try removing a bump, handling noise or silence at the edges. A crossfade blends the end and beginning; it cannot remove a loud event from the middle of the file. Choose a quieter section if the repeat still distracts you.
4. Make a recording playlist if you want variety
For more than one recording, create a playlist and arrange the recordings in the order you want. NOYZ plays recordings one after another; that is a different choice from layering several sounds at once.
Try one recording first. If the sound already suits you, there is no need to build a collection before using it. Keep originals and any important backups outside the app as well.
5. Choose how the session ends
For bedtime, choose a sleep timer with a gentle fade or let the sound continue. For work or reading, use Focus for a timed session. Start at a comfortable volume and check the audio output you actually want.
Before travelling, try playback with the screen locked and the connection off. Purchase restoration needs the App Store, so handle it in advance. If headphones disconnect, NOYZ pauses; reconnect them and press Play to continue.
