Smaart for Windows

Overview of Smaart by EAW

Smaart, created by EAW, is a professional audio analysis application that gives sound technicians a clear visual view of what is happening inside an audio system. It reveals the frequency composition of signals and lets users quantify how systems and rooms respond to sound. The program is designed to diagnose audio issues and guide corrective actions with precise measurement tools.

Core Capabilities

• Real-time dual-channel FFT analysis for simultaneous comparison of two signals
• Visualizations that show time behavior, spectral content, impulse responses, and tonal information
• Tools for measuring system and room responses to test tones and live signals
• Hardware integration for use with dedicated measurement devices and interfaces

Technical Details

Smaart combines both hardware-assisted and software FFT analyzers to produce accurate, low-latency measurements. Its displays include spectrograms and impulse response plots that help isolate problems such as resonances, delays, or mismatched filters. By correlating input and reference signals, the software can reveal phase and magnitude differences between sources.

How Sound Engineers Use It

• Compare the output of one device to another to find anomalies or verify alignment
• Apply system equalization and make timing corrections to improve clarity and coherence
• Identify and mitigate feedback paths and problem frequencies in live environments
• Validate speaker placement and room treatment by analyzing measured responses

Typical Workflow Example

• Capture a reference signal and the system output for simultaneous analysis
• Examine the impulse response and spectrum to locate peaks, dips, and delay
• Implement corrective EQ, time alignment, or acoustic changes and re-measure to confirm improvements

Summary

Smaart is a comprehensive diagnostics suite for audio professionals, combining precise measurement, visual feedback, and hardware compatibility to troubleshoot and optimize sound systems and spaces.
