Tunelabs

Tunelabs is a free professional-grade real-time audio analyzer designed for
audio installers, tuners, and enthusiasts who want accurate frequency analysis without the cost.

REAL-TIME ANALYZER (RTA)
• 6, 8, 16, and 31-band octave analysis (IEC 61260 standard)
• Peak hold — retains the highest level per band with slow decay
• Smoothing — exponential smoothing for stable, jitter-free readings
• Supports built-in, wired 3.5mm, and USB microphones

MICROPHONE CALIBRATION
• Import .cal and .csv calibration files for corrected measurements
• Per-profile noise floor calibration to reduce background noise
• Multiple mic profiles — switch between microphones easily
