• Project Management. Creation and administration of audio track projects with all data stored in JSON format. Media files are automatically collected into specific project folders. Each project is saved as a single .liveplay file containing references to all associated media elements and settings.
• Integrated YouTube Downloader. Direct audio download from YouTube in MP3 format with automatic import into the playlist. The function converts YouTube links to local audio files without requiring external applications.
• Hierarchical Playlist Structure. Organization of audio tracks into groups and subgroups for complex presentations. The organization allows managing shows with multiple segments and transitions between different parts of the presentation.
• Multichannel Playback. Ability to play multiple audio tracks simultaneously. Each track maintains its individual volume control and independent playback progress.
• Precise Audio Trimming. Setting entry and exit points to play only specific sections of audio files. Trim points are defined visually on the waveform representation of each track.
• Individual Volume Control. Audio level adjustment per track with a range of -60 to +10 decibels. Each channel maintains its independent volume setting during playback.
• Real-time Progress Bars. Graphical visualization of playback progress with remaining time for each active track. The display shows the current progress and total duration of the track.
• Emergency Stop. Immediate interruption of all playing tracks with a single click. The function simultaneously stops all active audio channels in the playlist.
• 16-Slot Cart Player. Quick access system with 16 buttons for triggering frequently used tracks. Slots are assigned by dragging elements from the main playlist.
• Drag-and-Drop Import. Adding audio files to the playlist by dragging from the file explorer. Files are automatically copied to the project folder.
• Color Coding. Assignment of distinctive colors to tracks for quick visual identification. Coding facilitates the visual organization of different content types in extensive lists.
• Index Addressing. Access to tracks via their position in the list using numerical format. The system allows referencing tracks using coordinates like "0,1,2" for precise navigation.
• UUID Identifiers. Assignment of universally unique identifiers to each track for reliable activation. UUIDs remain consistent regardless of reorganizations in the list.
• Waveform Visualization. Graphical representation of the audio file's waveform. The visualization aids in the visual identification of trim points and audio content.
• Ducking Behavior. Configuration of interaction between tracks with three modes: stop other tracks, duck other tracks, or allow simultaneous playback at full volume.
• Start Behavior. Configuration of automatic actions when starting playback, including activating the next track, playing a specific track by UUID or index, or playing the first items in groups.
• End Behavior. Configuration of actions upon playback completion, including continuing with the next track, jumping to a specific track, repeating the current track, or simply stopping playback.
• REST API Remote Control. Activation of tracks from external applications via HTTP endpoints. The local server operates at http://localhost:8080 and responds to simple GET requests.
• Customizable Themes. Selection between dark and light themes with 18 predefined accent colors. Each project can maintain its own visual appearance settings.
• Multilingual Support. Interface available in 20 languages including Spanish, English, Greek, French, Italian, Portuguese, Arabic, German, Swedish, Norwegian, Russian, Japanese, Chinese, Hindi, Bengali, Turkish, Korean, Albanian, and Urdu. Full support for right-to-left layout in Arabic, Farsi, and Urdu.
• Automatic Updates. Automatic checking for new versions when starting the application. One-click download and installation of updates via GitHub releases system.
