SAS Audio Processor is a suite of 25 audio processing tools that exposes audio editing capabilities as MCP tools via DeclarAgent. The toolset includes everything from basic processing like trim, normalize, and convert to advanced effects like EQ, reverb, and pitch-shift, plus analysis tools for key detection and loudness measurement.

Built specifically for integration with Claude Code and other MCP clients, SAS Audio Processor lets developers manipulate audio files directly through AI chat interfaces. The tools accept WAV files and return structured JSON results, making them ideal for automated audio workflows. Installation involves setting up DeclarAgent and adding MCP server configuration to your Claude settings.

The processor includes both single-step tools and composite operations that chain multiple processes together. For example, the master-track tool automatically applies normalize → compress → limit, while tempo-match analyzes BPM and time-stretches audio to a target tempo. With capabilities spanning processing, effects, analysis, MIDI extraction, and multi-step composites, SAS Audio Processor brings professional audio editing to AI-powered development environments.
