Äänportit
Äänportit is a Finnish term that translates to "sound gates" or "audio gates." In the context of audio engineering and music production, an äänportti refers to an audio effect that controls the volume of a signal. Specifically, it allows the signal to pass through only when it exceeds a certain threshold, and it silences the signal when it falls below that threshold. This is achieved through a threshold setting, which determines the minimum signal level required to open the gate. Additionally, an äänportti typically has controls for attack, which dictates how quickly the gate opens once the signal crosses the threshold, and release, which governs how quickly it closes. Decay can also be a parameter, controlling the duration the gate remains open before starting its release.
The primary function of an äänportti is to reduce or eliminate unwanted noise. This can include background
