A .NET command-line tool that simultaneously records audio from both microphone input and system audio output (speaker).

• Concurrent recording from microphone and system audio
• Automatic silence detection and handling for speaker output
• Timestamped WAV file output
• Simple command-line interface

• .NET 8.0 SDK
• Windows OS (required for WASAPI loopback capture)
• Audio input device (microphone)

1. Clone this repository: git clone https://github.com/yourusername/recorder.git

2. Navigate to the project directory: cd recorder

3. Build the project: dotnet build

Run the application: dotnet run

The program will:

1. Start recording from both microphone and system audio
2. Create two WAV files with timestamps (e.g., 20240315_143022.mic.wav and 20240315_143022.speaker.wav)
3. Continue recording until any key is pressed
4. Save both recordings automatically

• {timestamp}.mic.wav - Recording from microphone input
• {timestamp}.speaker.wav - Recording from system audio output

• NAudio (2.2.1) - .NET audio library

• Uses WASAPI loopback capture for system audio recording
• Implements silence detection and handling for speaker output
• Utilizes async/await pattern for non-blocking I/O operations
