WavSnap

What WavSnap is

WavSnap makes audio-reactive videos and audiograms by pairing audio with artwork, captions, text, and motion. Its editor supports multiple clips, trimming, fades, reordering, merging, EQ, compression, and loudness tools. You can import subtitles or transcribe on-device with Whisper, then use word-level timing and karaoke styling. Exports include MP4, WebM, GIF, and PNG; MP4 choices are 720p, 1080p, and 4K. Normal editing and export run locally in the browser, and WavSnap says files are not uploaded to its processing server. Gemini transcription is an optional cloud feature: with explicit confirmation, compressed audio is sent to Google's Gemini API, and the web app saves the key in browser local storage. The free plan has no account requirement or watermark, supports audio files up to 100MB, and allows up to 10 audio segments. Editions include a hosted web editor, Windows x86_64 desktop application, and self-hosted Docker edition for Linux AMD64 servers; all use the portable .wavsnap project format.

Who it suits

WavSnap may suit podcasters, musicians and producers, content creators and educators, or social media managers who need audio-led video and audiogram editing. Its browser, Windows, and self-hosted Linux editions offer different ways to work.

Limits

The free plan allows audio files up to 100MB and up to 10 audio segments. MP4 exports can be set to 720p, 1080p, or 4K.

Getting started

1. Open the hosted editor at wavsnap.com, or use the Windows x86_64 app or Linux AMD64 Docker edition
2. Start without an account on the free hosted plan
3. Load audio files up to 100MB and add up to 10 audio segments
4. Add artwork, captions, text, and motion, then edit the audio clips
5. Export locally as MP4, WebM, GIF, or PNG

Verdict

WavSnap offers audio editing, captions, and local exports across web, Windows, and self-hosted Linux editions. Note the file and segment limits, and that Gemini transcription involves sending compressed audio to Google's API after confirmation.
