Built for investigators
Capable, precise, and straight with you
-
Measured, not implied
Every reading names its units and its source. When a sensor is missing, the tool says so instead of showing a number it cannot support.
-
Real signal paths
Genuine DSP throughout — AudioWorklets, phase vocoders, HRTF panning, inverse FFT. Nothing is a looping sample dressed up as an instrument.
-
Private by construction
Microphone, camera and files are processed on your device. There is no account, no upload and no analytics following you between tools.
-
Honest about what it is
These are instruments and sound tools. They can describe a recording; they cannot tell you what caused it, and they never claim to.
Start with a room and a microphone
The EVP recorder captures a take and marks the segments whose audio resembles speech. The analyzer then tells you what is actually in the file — mains hum, clipping, codec limits — before you decide anything about it.
