A story worth hearing
Three clear steps
From source audio to finished video
- 1
Add your audio
Load MP3, WAV, OGG, FLAC, or M4A audio. Trim the useful moment, arrange multiple clips, and set fades or volume.
- 2
Build the scene
Choose an aspect ratio, add artwork and text, then style an animated waveform or another audio-reactive visualizer.
- 3
Caption and export
Import subtitles or create captions, preview the complete composition, and export a clean social-ready video.
An audiogram editor, not a one-click watermark template
WavSnap keeps the quick three-step workflow while giving you control over the details that make a clip look intentional.
Flexible layouts
Create vertical 9:16 stories, square 1:1 posts, 4:5 feed videos, or 16:9 widescreen clips from the same project.
Audio-reactive layers
Make visualizers, text, artwork, shapes, and captions respond to overall level, bass, mids, highs, or transients.
Portable projects
Save a .wavsnap archive with project settings and media so you can continue later or move the edit to another device.
Practical guide
What makes a useful audiogram?
Normal editing and export stay on your device. Optional cloud features are disclosed before data leaves it.
Start with one clear moment
A strong audiogram is usually built around one idea: a sharp answer, memorable quote, hook, announcement, or musical section. Trim away the lead-in before you design the frame. A shorter, self-contained clip is easier to understand without the full episode.
Use the timeline to set the exact source range and preview the cut with its captions. If the clip combines an intro and a quote, WavSnap can arrange multiple audio segments in one project.
Design for the destination
Choose the publishing format before positioning text. Vertical video gives captions and faces different safe areas than a square podcast card or a widescreen YouTube upload. WavSnap can reposition the composition when the aspect ratio changes, but every version should still be checked before export.
Keep the waveform visible without letting it compete with the quote. Contrast, font size, caption line length, and safe guides matter more than filling every part of the canvas.
Keep the audio as the source of truth
The animation should support what the listener hears. Use level response for broad motion, frequency bands when bass or treble should drive a layer, and transient response for short attacks. WavSnap does not pretend that amplitude response is automatic BPM or beat-grid editing.
Normal editing and export happen on your device. Optional cloud transcription is clearly identified before any audio or caption text is sent to another provider.
Questions about audiogram maker
Is WavSnap's audiogram maker really free?
Yes. You can open the hosted editor without creating an account and export without a WavSnap watermark.
Can I add captions to an audiogram?
Yes. Import SRT or VTT captions, create cues manually, transcribe on-device with Whisper, or deliberately choose the optional Gemini workflow. Caption styling includes karaoke and speaker options.
Which audiogram sizes can I create?
WavSnap includes 16:9, 1:1, 9:16, and 4:5 layouts plus custom dimensions, covering common YouTube, TikTok, Reels, Stories, and feed formats.
Does WavSnap upload my podcast or music?
Normal editing and export run locally in your browser. Optional cloud transcription sends data only after you choose that workflow and confirm it.
