About EVP Generator

EVP Generator

A tracker grid where rows are moments and columns are voice channels. Type a line and it becomes syllables that drive a formant synthesiser, rendered through a receiver chain over a static bed, and mixed offline with per-row effects including reversal, gating and tuning sweeps.

The whole pattern is rendered by an OfflineAudioContext, roughly thirty times faster than real time, so the preview and the exported WAV are the same audio. Different words genuinely produce different formant trajectories rather than a generic mumble.

How to use EVP Generator

  1. Each row of the tracker grid is a moment in time and each column is a voice channel. Use + and − to add or remove voices.
  2. Type a line into a row. It is split into syllables that drive a formant voice, so different words produce genuinely different sounds.
  3. Shape the overall result with the pattern settings: row length, the STATIC BED behind the voices, the RECEIVER colouring and the DELIVERY of each line.
  4. Add per-row effects such as reversal, gating, rises, drops and tuning sweeps.
  5. Press Space to play. RESEED gives a new variation of the same pattern; CLEAR starts over.
  6. Render and download the result as a WAV with ⌘S (Ctrl+S on Windows), or the download button.

Tips

  • Short lines of one to three words work best. Longer phrases become a stream of syllables that is hard to follow under static.
  • Keep the seed if you like a result. The same seed and pattern always render the same audio.

Questions

What is the EVP Generator for?

Making EVP-style sound effects for videos, games, podcasts, films and haunted attractions. You decide what the voices say and the generator renders it as a fragment heard through a weak receiver.

Is the voice text-to-speech?

Not in the usual sense. It does not use a recorded or neural voice. Typed words become syllables and vowel shapes that drive a formant synthesiser, so the result sounds like a voice through static rather than clear speech.

Can I use the WAV in my project?

Yes. The audio is synthesised from scratch in your browser, contains no samples, and is yours to use.

Why does the preview sound exactly like the download?

Both are rendered by the same offline process, roughly thirty times faster than real time, so there is no difference between what you hear and what you save.
