Sound field testing software SIASmaartLive

SIA SmaartLiveis an excellentSound field testThe software can conduct on-site sound field testing for stage performances and small and medium-sized parties to find the howling point of the microphone.
SmaartLiveIt is a software based on a dual-channel audio analyzer that can perform a large number of measurement tasks required by professional audio. Since SmaartLive cannot replace people's subjective hearing evaluation, it is necessary to configure an appropriate measurement platform according to specific measurement tasks, and adjust, optimize, and improve the system.
 

Function introduction

Spectrum measurement
Used for noise measurement, visual measurement of sound signals, determination of acoustic feedback frequency of sound reinforcement systems, optimization of sound systems and monitoring of sound signals.
Frequency response measurement
The real-time transfer function is a useful tool for adjusting equalizers and electronic crossovers in sound systems.
When comparing the input and output of the audio system, this comparison operation is used to find the difference between one signal and another signal. Relying on this comparison operation, its frequency response (including amplitude and phase) can be calculated extremely accurately.

Delay and impulse response measurements
In the pulse mode, software is mainly used to measure and display the impulse response of the sound system to find the time deviation between the two input signals, that is, the time delay. The pulse mode layout graphic shows the energy-time relationship, not the energy-frequency relationship.

Sound pressure level measurement
1) Scale of sound pressure level
2) Readout of signal level and sound pressure level
