## What it is
A collection of command-line and GUI tools that capture and analyze microphone audio to recover keyboard keystrokes acoustically. Its Keytap tools guess pressed keys from typing sounds, using training data or English n-gram statistics.

## Use cases
- recover typed text from keyboard audio recordings
- test if my keyboard is vulnerable to acoustic eavesdropping
- analyze keystroke sounds captured from a microphone
- demonstrate acoustic side-channel keyboard attacks
- record and inspect audio from the command line

## When to choose
- you want to demonstrate or research acoustic keyboard side-channel attacks
- you need to recover text from a recording of typing sounds without training data
- you want a self-contained C++ toolset for audio capture and keystroke analysis

## When to avoid
- you need a production-ready or stealthy surveillance tool
- you expect reliable text recovery on noisy keyboards or environments
- you need a maintained product with ongoing feature development

## Facets
- artifact type: cli-tool
- maturity: maintenance
- function: audio-processing, speech-recognition, security, cli, gui
- domain: security, developer-tools
- platform: windows, cpp, cross-platform, browser
- tags: acoustic-eavesdropping, keyboard-attack, keytap, audio-analysis, microphone, keystroke-recovery, security-research, audio, command-line, linux, macos
