Do SmaartLive and Smaart Acoustic Tools generate any kind of stimulus signal?
Yes. SmaartLive can generate several types of pseudo-random noise, variable-frequency single and dual sine wave, and FFT-synchronized, logarithmically swept sine wave signals. Additionally, any standard wave file may be looped continuously, allowing users to create their own test signals. The Intelligibility module in Smaart Acoustic Tools provides a pink noise generator and a wave file loop option for use in dual-FFT impulse response measurements and an MLS generator for MLS measurements. Note that to use the computer as a signal source for measurements, your sound hardware must be capable of full-duplex operation (playing and recording simultaneously). Most newer sound hardware does have this capability however some older devices may not. Keep in mind, that SmaartLive is a stimulus-independent measurement system and allows you to make measurements using a wide variety of test signals. Use of the internal signal generator is entirely optional and depending on your measurement applicat
