The Audio Output Control will allow you to change the way __prod_name outputs audio while recording or acquiring. All changes take effect immediately. The Audio Output Control can be launched from the View menu of __prod_name:
There are also multiple ways to view the Audio Output from the plots and plot windows. This varies by type, see the reference guide entry for the plots and plot windows of the specific type you wish to change.
Audio Output Device Section
|
|
| 1. Audio Device Selection | This is a list of all of the audio devices on your system that can be used by __prod_name for audio output. If you do not see the audio device you wish to use, it may not be compatible with __prod_name, or is not properly installed. Clicking on a device in the list will allow you to change the settings for that device in __prod_name. You will notice that when you click on a device, the name appears at the top of the configuration portion of the window. __prod_name will output audio on all of the devices at the same time. Your Primary Sound Driver can be changed through the Windows control panel. See your Windows documentation for more information. If the acquisition hardware you are using supports audio output, the outputs will be shown in this window. See your acquisition hardware documentation for more information on the audio output capabilities of your hardware.

| 2. Mute All | Checking this box will mute all audio channels on all audio devices. |
Audio Device Configuration
|
|
| 1. Configuration Options | This portion of the display contains all of the options that you can change for each device. The changes you make here will only affect the selected device, and will take effect immediately. __prod_name currently supports stereo output devices. Changing the selection in the Audio Output Device list will change the title of this section.
|
| 2. Audio Channel Setup | The setup for left and right channel audio is identical. All settings on the left or right channel can be heard through their respective speakers connected to the selected audio device.
|
| 3. Acquisition Entity Selection | __prod_name can output audio for both spike and continuously sampled channels. When you select an acquisition entity from the list, you should immediately hear it on the channel you are configuring. The number of channels in the channel selection list will be determined by the selected acquisition entity. You may only select one acquisition entity per audio channel. However, the same acquisition entity may be used on a different audio device or channel. Selecting None as the acquisition entity disables output on the selected audio device and channel. All devices will initially start out with None selected for the acquisition entity unless configured to do otherwise. The audio heard on the output channel will already be filtered and amplified according to the settings for the selected acquisition entity. Spike acquisition entities will output the continuous signal as audio, not extracted spikes.
|
| 4. Channel Selection | Here you will be able to select the channels for the selected acquisition entity that you wish to hear. This is mainly used for multi-channel acquisition entities such as tetrodes and stereotrodes. When you select a new acquisition entity, all of the channels available for that acquisition entity will be displayed, and their audio output will be enabled. To disable output for a specific channel, uncheck the box next to the channel you want to disable. You should immediately hear the channel silenced on the audio output. Checking the box next to a channel should immediately begin outputting the audio for that channel. All channels are output individually, there is no summing of the channels. So if you had two different songs playing on two different channels, you would hear both songs being output through the speaker. |
| 5. Volume | The volume slider here is used to amplify the audio signal within __prod_name. To make the sound louder, move the slider to the towards the word Volume. Moving the slider in the opposite direction will quiet the audio. Changing the volume in __prod_name has no effect on your Windows sound settings or the amplification of the signals recorded by __prod_name. Changes in the input range of your signal will also affect the volume level for __prod_name. Input ranges that are closest to the actual input signal will provide the largest range of control over the volume. Changes in your Windows audio settings will add or subtract amplification on top of the __prod_name volume setting. |
| 6. Mute | Checking this box will mute the audio on this channel of the selected audio device only. The volume slider will be unavailable when the channel is muted. Unchecking the mute option will restore the output to the previous volume and re-enable the volume slider. This setting has no effect on the signals recorded by __prod_name. |
