Choose or record the sound
Select compatible audio from Files, open a video from Photos or Files, or start a recording. When a video contains several audio tracks, choose the one you want to process.

Change the character and space around a sound.
Open an audio file, choose an audio track from a video, or record a new sound. Then try 17 playful character, room, device, and atmosphere presets without uploading the recording or media.
Three sources, one focused editor
How to apply a sound filter on iPhone.
The source stays unchanged. Every source creates a separate M4A audio result. For a video, ClipFlow reads and processes only the selected audio track; video frames do not enter the result.
Try an effect
Pick one of 17 presets or keep the Original, play a preview, and drag the progress control to hear another point in the sound.
Create and continue
Generate the filtered M4A on device, save it, continue through another compatible audio tool, or choose Add as Music or Add as Voiceover.
All 17 sound presets
Character: Deep Voice, High Pitch, Robot, Alien, and Monster. Space: Small Room, Hall, Deep Well, Large Tank, and Valley Echo. Device: Telephone, Radio, Broken Speaker, and 8-bit. Atmosphere: Underwater, Behind a Wall, and Ghost Voice.
These are intentional creative filters. Deep Voice and High Pitch make a voice sound lower or higher, but ClipFlow does not describe them as natural gender, age, or identity transformation.
A recording view that responds to your voice
Recording starts only after you tap the record control and grant microphone permission. A live energy waveform reacts to the sound level while the timer runs, with controls to pause, resume, stop, discard, or record again.
ClipFlow keeps the recording as an unfiltered source so you can change the preset without recording again. The source recording is stored only in app-managed local temporary storage for the current workflow; it is not uploaded.
Local processing and clear output
Preset preview, audio processing, and export run with Apple media frameworks on your device. Audio Effects requires ClipFlow Pro. It applies one preset to one selected audio track at a time rather than presenting a professional multitrack mixer.
