How AudioMap synchronizes timing for accurate measurements

For accurate measurements, AudioMap must know precisely when signals leave your speakers and arrive at your microphones. This timing synchronization is critical for phase accuracy and proper system alignment.

Your I/O Availability

How many spare inputs and outputs do you have?

Accuracy Requirements

How critical is phase precision for your work?

Setup Complexity

Do you want instant setup or maximum accuracy?

Virtual Reference Mode

How It Works

AudioMap generates timing references entirely in software, eliminating the need for physical loopback connections. The system uses Round-Trip Latency (RTL) calibration to compensate for interface delays.

Signal Types:

• Timing Reference: Virtual
• Transfer Function: Virtual

When to Use

No spare I/O available on your interface
Quick measurements or system checks
Mobile measurement setups
Frequency response optimization (phase less critical)

Note: Requires RTL calibration. Phase accuracy depends on interface clock stability.

Transfer Function Calculation

H(f) = Y(f) / X(f)

Where Y is the microphone signal and X is the virtual reference with RTL compensation applied
