AEC3

AEC3 Extracted From WebRTC

This is a build adaptation for macOS Apple Silicon platform of the original project: ewan-xu/AEC3

Build

Windows

• Visual Studio 2015

macOS (Apple Silicon/ARM)

Prerequisites

1. Install Homebrew (if not already installed):

   /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

2. Install required packages:

   brew install cmake

Build Steps

1. Clone the repository:

   git clone https://github.com/EitanWong/AEC3.git
   cd AEC3

2. Build using the provided script:

   cd demo
   chmod +x build.sh
   ./build.sh

   Or manually:

   cd demo
   mkdir -p build
   cd build
   cmake ..
   make -j$(sysctl -n hw.ncpu)

Usage

The demo application processes audio files for acoustic echo cancellation:

./demo ref.wav rec.wav out.wav

Where:

• ref.wav: Reference/far-end signal (e.g., audio played from speakers)
• rec.wav: Recorded/near-end signal (e.g., microphone recording with echo)
• out.wav: Output file where the processed audio (echo-cancelled) will be saved

Test

See demo.cc for example usage.

Note

The AEC3 (Acoustic Echo Cancellation) implementation is extracted from the WebRTC project and adapted to run as a standalone library. This repository contains build scripts specifically for macOS Apple Silicon platform.
