# Loopback Recorder
LoopbackRecorder is a WPF application for Windows that allows you to record audio from system playback (loopback) and input devices, with optional silence removal, format conversion, and speech-to-text transcription using OpenAI Whisper models.
## Features
- **Record System Audio**: Capture audio from playback (render) and input (capture) devices.
- **Silence Removal**: Optionally skip silent segments during recording.
- **Format Conversion**: Convert recorded WAV files to AAC (MP4), MP3, or WMA formats.
- **Transcription**: Automatically transcribe recordings to text using Whisper models.
- **Device Selection**: Choose from available audio devices for both playback and capture.
- **Settings UI**: Configure options such as silence threshold, output formats, and transcription model.
## Requirements
- Windows 10 or later
- [.NET 9 SDK](https://dotnet.microsoft.com/download/dotnet/9.0)
- [NAudio](https://github.com/naudio/NAudio) (included via NuGet)
- [Whisper.net](https://github.com/Const-me/Whisper) (included via NuGet)
## Getting Started
1. **Clone the repository**:
2. **Open in Visual Studio 2022**:
- Open `LoopbackRecorder.sln`.
3. **Restore NuGet packages**:

## Usage
1. **Select Devices**: Choose playback and/or capture devices from the dropdowns.

5. **Conversion**: If enabled, the recording will be converted to the selected format.
## Configuration
