The trial is full-featured, but is limited to 5 minutes of usage per session.

Recording You can choose any input device for recording and select which channel you want (left, right or both). Microphone calibration is also supported for even more precision in measurements.

Calibration EasyRTA has an automated calibration procedure which allows you to make very precise measurements on any device on line input or line output. Audio measurements can also be performed with an external microphone.

Spectrum analyzer Besides being a powerful real-time spectrum analyzer, EasyRTA also features an on-screen measuring tool which can be used for measuring amplitude and frequency in any given point.

Signal generator EasyRTA can generate various signal types, such as: Sine, Triangle, Sawtooth, Square, Impulse, White Noise, Pink Noise, Dirac Pulse and Short Sweep with frequencies from 20 Hz up to 20 kHz and amplitudes in four 10 dBu steps (-50, -40, -30, -20, -10 and 0 dBu).

Sampling EasyRTA has fixed sample rate to 48000 samples per second, and fixed 8192 FFT number of points. Therefore the latency time (period which is needed to collect a packet of FFT points) is 171 ms, providing measurment from 6 Hz to 24 kHz.
