| Channel Properties
To set the properties for any channel, click Options, select the device then click Properties. Device Properties Name This is the name of the channel or line that will be displayed on the main window and as part of the file name when you Find and Play the recordings. Play 'Recording Tone' In some environments you are required to play a tone while recording. To do this, tick this box and enter the number of seconds between tones. Play 'Recording Started' Prompt This option is usually only applicable when using VRS to record telephone calls with a professional telephony board. If you tick this option and select the correct play device (corresponding to the record device above) whenever recording is started a prompt will be played out the device. Play Device If 'Recording Tone' or 'Recording Prompt' have been selected, then a sound output device will need to be selected to play the audio for this channel. Simply select the device from the pull down list. The default play output channel is normally your sound device. Record Device Select the sound input device to be used to record this channel in the pull down list. You can use a single shared stereo device to record 2 mono channels by selecting the same device for both channels but selecting Left for one channel and Right for the other. You might need a Y cable to connect 2 mono sockets to a stereo plug (available at your local electronics store). The default record input channel is the "Windows Record Mixer". A better option is to select the required input channel which VRS will use directly. Usually this is "Line-In" or "Microphone" depending on which socket is used. If you select a channel you can adjust the input record volume. Telephony Device for Caller-ID This option only applies if you are using VRS to record phone calls, your phone network supports caller ID and you have caller-id modem(s) or telephony boards in the computer. If all of the above apply VRS can log the number (and name) of callers using the modem to decode the incoming caller ID information. Tick this option and select the telephony device (CID supporting) in the pull down list. Stop/Start Control Record Start/Stop Control Mode Start/Stop Control Mode: Voice Activated Recording If you select this option for a channel, VRS uses the input signal level to start and stop recording. When the recording is above the threshold (default -18dB), recording starts. When recording drops below the level for more than the detect time (default: 12 seconds) recording stops. This detect time is not used as a delay in starting the voice activated line. If you find that the recording does not start, you may need to increase the device record volume. If it does not stop, reduce the record volume. To adjust the record volume open the Windows Record mixer or adjust the input channel volume. Start/Stop Control Mode: Hardware If you select this option for a line, VRS recording is controlled by hardware connected to either a game controller port or a serial (COM) port. If you are recording telephone lines, this could be the Telephone Interface Device trigger. If you are using a game port control device, a 4 button "Game Controller" device must be enabled from the Windows control panel. For more information, please see: Hardware Connection. Start/Stop Control Mode: Continuous If you select this option for a line, the line will be recorded continuously. A new file is created for every hour so that you can easily locate a particular recording. This option is usually used only where you want to record 24 hours a day. For example, radio station program logging. The file length is set from the Recordings tab of Options - "Maximum record file length". Start/Stop Control Mode: Manual When this mode is selected, record can be started or stopped by clicking on the button corresponding to the channel on the VRS main window. You can also use start or stop by right-clicking on the NCH icon on the task bar tray and selecting the relevant channel. With a professional telephony device such as a CAHTA board (see www.nch.com.au/vrs/acc for info), VRS can use that device to detect if a phone line is off-hook or not (in addition to obtaining caller ID information). This does not work on voice modems. To use this option you must have the "Telephony Device for Caller-ID" ticked and selected. |
