Klipwave: Offline Audio Editor

Klipwave is a complete offline audio editor, MP3 cutter, voice recorder, and voice changer. Record, edit, and transform sound entirely on your device: no internet connection, no account, and no cloud uploads. Your recordings never leave your phone, and the app is free with no ads.

RECORD
Capture voice memos, interviews, and field audio straight to WAV with the built-in voice recorder. Choose your sample rate and bit depth (16-bit or 24-bit, where your device supports it) and start fast with ready-made recording presets.

EDIT WITH PRECISION
Trim, cut, copy, paste, split, and delete with sample-level accuracy. The audio cutter works down to the individual sample, so you can fade in or out, silence a section, duplicate audio or insert silence, and undo up to 20 steps if you change your mind. Zoom in up to 8x on a stereo waveform with per-channel lanes, loop any selection, and scrub playback anywhere from half speed to double speed.

60 AUDIO TOOLS, ONE APP
Noise & restoration: noise reduction, hiss reduction, de-hum for 50/60 Hz mains hum, click removal, crackle removal, DC offset correction, silence removal.

MULTITRACK STUDIO
Build layered projects across multiple tracks. Set volume, pan, mute, and solo per track, drag clips on a zoomable timeline, import several files at once, and mix everything down to a single file. It doubles as an audio joiner for merging takes end to end and as a podcast editor for full episodes.

CONVERT & EXTRACT
Convert between formats with the built-in audio converter, or pull the audio track straight out of a video file to get video to MP3 in one step.

ANALYZE YOUR SOUND
Read the frequency spectrum, check loudness in LUFS, and watch a stereo correlation (phase) meter update in real time.

EXPORT & SHARE
Export to WAV, MP3, and other device-supported formats. Turn any clip into a ringtone with the built-in ringtone maker. Export a video with a waveform visualizer, or share your finished audio directly from the app.

PRIVATE BY DESIGN
Klipwave requests no INTERNET permission, so it cannot send your files anywhere even if it wanted to. No sign-in, no account, no cloud processing, so your privacy stays intact. It is free, with no ads and no in-app purchases.

Built for podcasters, musicians, voiceover artists, students recording lectures, and anyone who wants a fast offline audio cutter, MP3 trimmer, voice changer, and sound editor without handing their files to a server.
