Detailed Description
Sound detector search for samples over a specified threshold.
Member Function Documentation
◆ detectSound()
|
overridevirtual |
Reads off new samples from the capture device, if such are available, then detect sound based over the specified threshold, estimating how long ago the sound appeared in each channel.

- SoundDetector::detectSound
Implements gramods::gmSound::SoundDetector.
◆ setCooldown()
| void gramods::gmSound::SoundBurstDetector::setCooldown | ( | float | t | ) |
Sets the cooldown time for a detection, i.e.
the time between two samples over the threshold that is considered another sound. Default is 0.1 seconds.
XML-attribute: cooldown
◆ setThreshold()
| void gramods::gmSound::SoundBurstDetector::setThreshold | ( | float | r | ) |
Sets the threshold used for detecting a sound event in the range 0-1.
Default is 70%.
XML-attribute: threshold
