ProDAW - Professional Digital Audio Workstation

A modern, high-performance Digital Audio Workstation (DAW) developed primarily in Delphi (Object Pascal) with performance-critical audio processing components written in x86/x64 Assembly for ultra-low latency.

Vision

ProDAW combines the workflow of Logic Pro, FL Studio's pattern-based sequencing, and modern AI-assisted music production. It is suitable for beginners and professionals while maintaining maximum performance and stability on Windows.

Architecture

Delphi Modules

• Audio Engine: Core audio processing with ASIO/WASAPI support
• MIDI Engine: Complete MIDI system with event handling
• Mixer: Professional mixing console with channel strips
• Project Manager: Project file handling and settings
• UI Framework: Modern VCL-based interface with docking panels

Assembly Modules

• DSP Routines: Ultra-low latency audio processing
• Filters: High-performance filter implementations
• Dynamics: Compressor, limiter, gate processing
• Analysis: Peak, RMS, LUFS metering
