Browser renders never upload your content. HQ renders run on our server for maximum compatibility.

About this tool

Social platforms bury raw audio, so podcasters turn clips into audiograms: videos with an animated waveform that reacts to the sound. Upload your clip, drop in cover art and a title, and Shortsmith renders a reactive waveform, progress bar and clock — all in your browser, so your audio never has to touch a server unless you choose the HQ render.

· 1080×1920 vertical MP4, 30fps — TikTok, Shorts & Reels ready
· Free browser rendering with WebCodecs; optional HQ server render
· No account needed — AI autofill, voiceover & brand kit built in
