One of the main features of TrueRTA Level 4 is the ability to perform quick and accurate frequency response measurements. You can use the Quick Sweep function to generate a logarithmic frequency sweep from 10 Hz to 20 kHz and capture the response of your audio system in less than a second. You can also use the Pink Noise function to generate a random noise signal with equal energy per octave and measure the response of your system over a longer period of time. You can compare the measured response with a target curve or a reference measurement and adjust your system accordingly.
Another feature of TrueRTA Level 4 is the ability to perform distortion and noise measurements. You can use the THD+N function to measure the total harmonic distortion plus noise of your audio system at any frequency and level. You can also use the IMD function to measure the intermodulation distortion of your system caused by two or more frequencies. You can view the distortion and noise components in both the frequency and time domains and identify the sources of distortion and noise in your system.
A third feature of TrueRTA Level 4 is the ability to perform acoustic measurements. You can use the RT60 function to measure the reverberation time of your room at different frequencies. You can also use the ETC function to measure the energy-time curve of your room and analyze the reflections and echoes in your room. You can use these functions to optimize the acoustics of your room and improve the sound quality of your system. c481cea774
