The Sound Mode uses the microphone of your smartphone to detect sound events. It has three parameters:
Threshold: This value determines the level of the sound that must be exceeded to trigger. The measured sound level will we displayed in real time with orange bars. This will help you to understand where to set the threshold approximately to filter out the environment noise. You can move the threshold bar around the button by touching the grey bar.
Delay: This parameter defines the duration between the detection of the sound and the triggering of the camera. You can define the delay anywhere from 0 up to 999 milliseconds.
Mode: You can select one of the two possible modes. The modes are the “Continuous Shot” and the “Single Shot”. In the “Continuous Shot” mode, it will trigger the camera each time a sound event is detected. This can cause multiple pictures to be taken or multiple triggering of the flash. If you don’t want this to happen, you can select the “Single Shot” mode. In this mode, it will trigger the camera only once, and then it will stop. You will need to start the sound mode running again to take another picture.
In the sound mode, the distance between your sound source and the smartphone can make a difference. Due to the propagation speed of the sound, you may want to bring the smartphone closer to the sound source.
