A desktop application that allows you to record audio from specific applications on Linux. Built with Deno, Svelte, and WebView.

• List running applications with audio output
• Record audio from specific applications
• Record audio from different outputs of a specific applications
• Save recordings automatically to your Music directory

• Linux operating system
• PipeWire audio system (with pipewire-pulse for compatibility)
• Deno runtime installed
• pipewire-utils (for pw-dump, pw-metadata, pw-record, pw-play)
• pulseaudio-utils (for pactl)
• ffmpeg (for recording)

1. Clone the repository:

git clone <repository-url>
cd record

2. Build the application:

deno task compile

This will create an executable named record in the project root directory.

3. Run the application:

./record

1. The application creates virtual audio sinks for each application being recorded
2. Audio is redirected from the original application to its dedicated virtual sink
3. The virtual sink's audio is recorded to the selected audio format (Opus, MP3, FLAC, WAV, etc.)
4. Recordings are saved in ~/Music/RecordApps/<app-name>/ with timestamp-based filenames
