EchoWave is a browser-based video and audio editor for podcasters, musicians and social creators. It turns audio into shareable videos with captions, waveforms and AI voiceovers.
About EchoWave
What Is EchoWave
EchoWave is an online video and audio editor that runs in your browser. It started in 2018 as an audio to video converter that turned a podcast to video with a waveform, and it has grown into a full multitrack editor. The pitch is simple: professional-looking video without professional software or a download.
The core idea is repurposing. If you record audio, EchoWave gives that audio a visual form you can post on video-first platforms like YouTube, Instagram and TikTok. Podcasters slice episodes into clips with captions and waveform visualizers, musicians add reactive visuals to a track, and clippers cut long videos into Shorts and Reels.
The limits are worth knowing before you commit. Free editor exports stop at 720p with a small EchoWave badge, and the free plan keeps rendered videos for 24 hours. AI subtitles in 86 languages, AI voiceovers and voice cloning sit on the Pro plan and up, so the paid tiers are where most of the AI side actually lives. Videos cap at 60 minutes each on the free plan.
EchoWave is owned and operated by Lemon Vault LLC, a US company. Pricing is localized, so the dollar figures here may differ from what you see at checkout in another country.
Getting Started
- Open the editor in any modern browser. You can start without an account, and nothing needs installing.
- Upload video, audio or photos, paste from your clipboard, or record your screen, camera or mic straight into the timeline.
- Add captions with auto transcription, drop in AI voiceovers, and pick a music visualizer or template to give the project a look.
- Arrange everything on the multitrack timeline, then preview live before you commit to a render.
- Export in the cloud at up to 720p on the free plan or up to 8K on paid plans, and download the finished file.

Key features
Auto subtitles in 86 languages
EchoWave transcribes your video and turns the speech into editable text. You style captions with 176 presets and karaoke word highlights, then translate the result into any of 86 languages. Export captions baked into the video or as SRT and VTT files for editors.
AI voiceovers and voice cloning
AI Voice Studio turns a typed script into narration, splitting every paragraph into its own clip. You pick from 63 studio voices, or clone your own voice once and reuse it across projects. That makes voiceovers practical without recording gear.
Music visualizers and motion
There are 93 visualizer styles that react to your audio, plus progress bars, shapes and 126 ready-made animations. When a preset is not enough, you can keyframe 72 properties, and every frame previews live on the timeline.
Multitrack browser editor
The editor handles video, audio, images, text and overlays on a real multitrack timeline. Screen, camera and mic recording happen in the same tab, and stock photos, videos and sound effects are one panel away. Projects autosave and follow you between devices.
Batch rendering and API
Save any project as a template with text, image, video and audio placeholders. Batch render hundreds of variations from a CSV, or generate videos programmatically with the REST API and MCP server for AI agents.
Cloud rendering up to 8K
Exports render on EchoWave cloud servers, not your machine, so you can close the tab while a file processes. Paid plans reach 4K and 8K at up to 120 fps, in eight formats including MP4, WebM, MOV and GIF.
Pros and cons
Pros
- No install or account needed to start: the whole editor runs in a browser on Mac, Windows, Linux and Chromebooks.
- Strong AI toolkit on the Pro plan: subtitles in 86 languages, 63 AI voices and voice cloning cover captioning and narration in one place.
- Batch and API workflows: templates, CSV rendering and a REST API let teams produce hundreds of videos without manual editing.
- Generous free tier to evaluate: unlimited projects and videos at 720p, plus 90+ tools that export clean files with no watermark.
- Cloud rendering: exports run on EchoWave servers, so long renders do not tie up your device.
Cons
- The free editor carries a badge and a 720p ceiling: you cannot publish a clean, full-HD video without a paid plan.
- AI subtitles and voiceovers are locked to Pro: the $17 a month tier is the real entry point for the AI features most people come for.
- Cloud rendering means a wait: jobs queue on EchoWave's servers rather than finishing instantly on your machine.
- Account storage is short on the free plan: rendered videos are kept for just 24 hours, so you have to download them quickly.
