Use Waveform Generator to turn podcast audio into PNG, SVG, and JSON waveform assets for covers, reels, and landing pages.

Generate queued waveform PNG, SVG, and JSON outputs from heavy audio files with Railway-backed processing.
Audio teams often need a visual waveform long before they need a full video edit. The blocker is usually the same: the original file is too heavy for browser-only tools or the export options are too limited for real marketing assets. Waveform Generator turns one uploaded audio file into server-rendered peaks plus ready-to-download PNG, SVG, and JSON outputs.
Treat waveform generation as asset preparation, not a final design task. Pick the layout first, keep one visual preset per channel, and export the waveform once so podcast art, landing pages, and social clips share the same signal shape.
Before shipping the asset, verify three things: the waveform reflects the right edit or episode section, the output size matches the surface you are designing for, and the downloaded file type matches the next tool in the workflow. SVG is strongest for design teams, PNG is fastest for publishing, and JSON peaks are useful for motion or video pipelines.
Run the next episode intro or trailer through Waveform Generator, export the PNG and SVG pair, and keep the JSON file as the reusable base for future motion assets.
