SpectraWave Recorder

SpectraWave is an EVP voice recorder that is honest about what it is. It records the real room through your microphone, then lets you replay each clip slowed down, reversed, and noise-reduced to pick out faint voices, all on your device. Nothing is uploaded, no voices are fabricated, and your captures are saved reliably so they never vanish. For entertainment purposes only.

REAL MICROPHONE CAPTURE
- Record the actual room with a live level meter
- Every capture is saved reliably and survives relaunch
- Works fully in airplane mode: nothing is ever streamed

PLAYBACK THAT PICKS OUT VOICES
- Slow any clip to half speed to hear syllables
- Reverse it for classic backward-EVP review
- A clarity filter lifts faint sound out of the hiss
- All effects run on your device, on your real recording

MARK AND EXPORT YOUR EVIDENCE

WHY SPECTRAWAVE
- It just works. Real capture that always saves, the one thing every other recorder gets wrong.
- Honest. On-device audio and effects mean nothing is streamed and no voices are faked.
- No subscription. The core is free forever, and Pro is a single one-time purchase.
- Yours, privately. Your audio stays on your device and only leaves if you share it.

For entertainment purposes only. SpectraWave records real audio with your microphone and processes it with on-device effects. Results are not evidence of paranormal activity.
