Recommended by the magazine "Sound and Vision". Favourite audio engineers around the world: check out the reviews!
Exclusive ISO 1/3 octave calibration - can be adjusted to answer the phone microphone.
Audiotool FFTs sets microphone samples. Aliasing is reduced Hann window. SPL is calculated in real time. The spectra can be stored, and then loaded and displayed with the live range.
A pair of cursors can be shown that each of them can be moved to any position, and will display the SPL & time / frequency there.
Speaker polarity test can be used to check whether the speaker is connected in phase: connect the output Audiotool to the speaker under test, select the "Polarity" to the signal generator screen, then return to the RTA screen.
