Auto Recorder Pro threshold 5

The threshold has values between 1 and 10.

In telecommunications, a voice operated switch, also known as VOX or Voice Operated eXchange, is a switch that operates when sound over a certain threshold is detected. It is usually used to turn on a transmitter or recorder when someone speaks and turn it off when they stop speaking. It is used instead of a push-to-talk button on transmitters or to save storage space on recording devices. On cell phones, it is used to save battery life. Intercom systems that use a speaker in a room as both a speaker and a microphone will often use VOX on the main console to switch the audio direction during a conversation. The circuit usually includes a delay between the sound stopping and switching direction, to avoid the circuit turning off during short pauses in speech (From Wikipedia).

阈值具有1和10之间的值。

在电信，语音操作的开关，也称为VOX或语音操作交换，是检测到的声音超过一定阈值时操作的开关。它通常用于打开发射器或刻录机时有人说话，并把它关掉，当他们停止发言。它被用来代替一按即说按钮上的发射机或以节省记录设备的存储空间。在手机上，它是用来节省电池寿命。使用的扬声器在一个房间同时作为扬声器和麦克风会经常使用的VOX主控制台上的会话期间切换音频方向内部通信系统。该电路通常包括声音停止和开关方向，避免电路在短暂停关闭语音（维基百科）之间的延迟。
