echo-cancellation

A high-performance, modular audio & MIDI engine for .NET 8+. A complete toolkit for the entire audio lifecycle: Playback, Recording, Multi-track Editing, Pro Synthesis (MPE/SF2), Real-time DSP, and Visualization. Includes a unique security suite for AES-256 encryption, acoustic fingerprinting, and watermarking. Featuring SIMD and NativeAOT support.

Open-source AI meeting copilot - real-time transcription, echo cancellation, and AI assistance. Captures system audio + mic, cancels echo via WebRTC AEC3, transcribes with Deepgram, and gives you Claude/OpenAI help during meetings. Runs locally on macOS and Windows.

Echo Canceller, part of Voice Engine project

Speex Echo Canceller Python Library

FP-AUD-SMARTMIC1 provides a firmware running on STM32 which acquires audio signals of four digital MEMS microphones, elaborates them by means of embedded DSP libraries and streams the processed audio to both an USB host and a loudspeaker. Please check st.com where a more recent version of the software might be available.
