Software can be upgraded to Level Three (1/6th octave) or Level Four (1/24th octave). If you want to do acoustic testing of loudspeakers in addition to the above you will need a calibrated microphone (True Audio recommends the Dayton Audio EMM-6), a microphone preamplifier or mixer, an audio power amplifier to drive the speaker under test, and cables to connect the line-out of the sound card to the input of the audio power amp. To set up your own audio test lab you will need a digital voltmeter to calibrate TrueRTA for your sound card and a collection of cables and adapters for connecting electronic gear to your sound card for testing. TrueRTA also includes a digital voltmeter that reads true rms voltage and dBu levels, and an audio spectrum analyzer.
