How this analysis was created: This summary and feature list were written by an AI model that read the project's README and public documentation pages. Each feature links to the documentation it came from; stars, license and language come straight from the GitHub API. The model does not read the source code, and the analysis is refreshed when the project is re-analysed. Learn more on our About page.

Recorder is a JavaScript library for capturing audio from microphones and encoding the resulting data into multiple formats, including MP3, WAV, and WebM. It provides a unified interface for cross-platform audio recording across web browsers and mobile applications. The library functions as an audio signal processing tool and waveform visualizer, offering real-time visual feedback through frequency histograms and waveforms. It includes specialized capabilities for encoding and decoding dual-tone multi-frequency telephone keypad tones. The project covers a broad range of audio manipulation ca
EZAudio is an audio library for Apple platforms that provides standardized interfaces for microphone capture, file playback, and hardware output. It functions as a low-latency audio processor and visualization framework designed to manipulate audio buffers and route signals with minimal delay. The project features a hardware-accelerated waveform renderer for drawing real-time audio amplitudes and rolling plots. It also includes a Fast Fourier Transform analyzer that converts time-domain audio samples into frequency-domain data for spectral analysis. The library covers a broad range of capabi
The Android NDK samples provide a comprehensive collection of code examples demonstrating how to integrate C and C++ native code into Android applications. This repository serves as a practical guide for developers utilizing the Android Native Development Kit to implement performance-critical application components that require direct hardware access and low-level system interaction. The project highlights the use of the Java Native Interface to bridge managed code with native modules, enabling cross-language function calls and efficient data exchange. It demonstrates how to manage native act
This project is an acoustic keystroke recognition system and audio side-channel analysis tool. It identifies typed text by analyzing audio recordings of keyboard sounds through waveform correlation and linguistic frequency analysis. The system distinguishes itself by combining digital signal processing with a substitution cipher decryptor. It uses simulated annealing and n-gram probability maps to recover plaintext from encoded strings and identifies specific keys by comparing captured waveforms against trained sound profiles. The toolkit covers a broad range of capabilities, including real-
