FB Lead Chef TrueRTA (TrueRTA.exe). TrueRTA is a program that will analyze the spectrum of any audio input.
TrueRTA delivers real-time spectrum analysis for any audio input, giving you accurate frequency, dB, and amplitude visuals through your system’s sound card. Whether you’re analyzing a microphone feed, an audio CD, or any connected source, the program displays clean, dynamic graphics for fast audio diagnostics—ideal for studio calibration, home theater tuning, and advanced acoustic measurement.
With 1/24th-octave resolution across the full audio spectrum, TrueRTA lets you customize scales, parameters, and measurement ranges. Peak-hold tracking highlights maximum values reached at any frequency, helping you fine-tune room acoustics or troubleshoot sound system performance using high-resolution audio analysis tools and real-time audio monitoring workflows.
TrueRTA can also generate test signals from 1 to 22,050 Hz, adjustable to any amplitude level (in dBus). Choose from sine, square, triangle, saw, impulse, pink noise, or white noise waves—perfect for sound engineering tasks such as speaker testing, EQ balancing, and professional signal path verification.
