What Is Control Panel?

The DSP Solutions Audio Control Panel provides the user with direct control over DSP Solutions Audio Driver functions when a specific application does not provide a desired function.  Click the left mouse button on the area of the panel that you are interested in.


Volume/SynthVolume

This control allows the user to set the sound level for playback of either digitized audio (.WAV) or synthesized audio (.MID,.RMI,etc.) files. Click and hold the left mouse button while on the dial pointer (red dot for color monitors), then drag the pointer in a clockwise direction to increase the volume. Dragging the pointer in a counter-clockwise direction reduces the volume.

The mouse pointer may also be clicked at any detent point on the outside of the dial (black dots) to directly set the volume.

Other applications (such as the DSP Sound Station) may affect the volume setting.  The audio driver retains the level set by the last application to access the driver.

Changing the volume for digitized audio files also changes the volume for synthesized audio files, and vice-versa.  Note that if Mix WAVE/Synth is selected, only the Synthesized audio volume is affected by this control.  The digitized audio volume cannot be changed when Mix WAVE/Synth mode is selected.


Mixer

Mix Audio-In

Mix WAVE/Synth


REC Level

This control allows the user to set the sound level for recording digitized audio (.WAV) files. Click and hold the left mouse button while on the dial pointer (red dot for color monitors), then drag the pointer in a clockwise direction to increase the volume. Dragging the pointer in a counter-clockwise direction reduces the volume.

The mouse pointer may also be clicked at any detent point on the outside of the dial (black dots) to directly set the volume.

Other applications (such as the DSP Sound Station) may affect the level setting.  The audio driver retains the level set by the last application to access the driver.

The AUX= command line must be set to the DSP Solutions WAVE driver for this function to be enabled.


TEST Button

The TEST Button is a two-state button that toggles between TEST and STOP.  When pressed, the button changes to STOP and the Audio Control Panel plays a continuous loop sound clip at 8 bits, 11025 samples per second.  Click on the button a second time to stop the continuous play.

This function can be used to test the current volume setting if another sound is not being played.

If the WAVE driver is busy or unable to play a sound (Synth is playing in exclusive mode), the TEST Button will be displayed in gray and will not respond to mouse actions.


Command Buttons

Advanced/Basic


Advanced Control

When the Advanced command button is clicked, additional controls are revealed (except CD•NET Sound ). These controls allow the user to force the PORT•ABLE Sound parallel port to operate exclusively as a printer port, a sound port, or to automatically determine the appropriate usage (default). The Advanced button label is changed to Basic.

Click on the Basic button to hide the additional controls. The Advanced Control section is not available for the CD•NET Sound internal sound card.

Automatic

When Automatic Sound/Printer is selected, both sound and printing functions are enabled.  The PORT•ABLE Sound driver determine which function is to be used at any particular time.

The PORT•ABLE Sound device must be properly connected and powered up.


Sound Only

When Sound Only is selected, the sound functions are exclusively enabled.  In this mode, you will not be able to print even if there is a printer attached to the PORT•ABLE Sound pass-thorugh port. Use this selection when you have encountered printer conflict error screens while playing sound, and you do not require printing.

The PORT•ABLE Sound device must be properly connected and powered up.


Printer Only

When Printer Only is selected, the printer functions are exclusively enabled.  In this mode, you will not be able to play sound through the PORT•ABLE Sound . Use this selection when you have encountered printer conflict error screens while playing sound, and you do not require sound.

The PORT•ABLE Sound device is not required to be attached to the system in this mode.


Apply Now

Sends the Sound/Printer selection to the audio driver immediately.  The selection is not saved when Windows is exited. To save the setting as the default in SYSTEM.INI, click the Save button.


Save

Sends the Sound/Printer selection to the audio driver immediately, and save the setting as the default in the SYSTEM.INI file under the [PORT*ABLE Sound] section. The setting will be used the each time Windows is started. To apply the selection immediately, without saving it as the default, click the Apply Now button.


Cancel

Restore the Sound/Printer selection last sent to the audio driver. This command does NOT exit the Audio Control Panel.


Done

Click the Done button when finished manipulating the audio driver. The current volume and/or REC Level settings will be retained until another application changes them or until Windows is exited. The Mix Audio-In and Mix WAVE/Synth control setting are automatically saved in the SYSTEM.INI file under the [PORT*ABLE Sound] section.

The Advanced Control section settings must be saved explicitly by clicking the Save button in the Advanced Control section

Mix Audio-In

When checked, the audio driver allows audio from the Audio-In jack to be mixed with the digitized and/or synthesized audio from the sound device. Clear this check box if you want the external sound source to be temporarily muted while sounds from the computer are being played.

Note:	When the sound device is NOT playing digitized and/or synthesized audio, sound from the Audio-In jack is automatically routed through the sound device speaker.

The AUX= command line must be set to the DSP Solutions WAVE driver for this function to be enabled.


Mix WAVE/Synth

When checked, the audio driver allows both digitized audio (.WAV) and synthesized audio (.MID,.RMI,etc.) files to be played at the same time. When cleared, the driver reports that the device is busy if an application attempts to start playing one type of sound while the other is already being played.

Because of limitations imposed by the mixing of WAVE and Synthesis modes, it is desireable to leave this box cleared unless a specific application requires combination of the two audio types.

Note: When this box is checked, the following limitations apply:

•	Only 8 bit linear PCM format (standard .WAV files), or MuLaw PCM files may be played with the WAVE driver.

•	Software volume control of .WAV files is disabled (Volume control label changes to Synth Volume).


Display Indicators

WAVE Status Light

Synth Status Light


Synth Status Light

The Synth Status light is indicates the current operational mode of the Synthesizer device driver.  It has three possible states:

	When the LED is green, the Synth driver is currently open and probably, but not absolutely, playing synthesized audio.  If you do not hear sound, it is possible that an application did not close the Synth device when it was finished.
	When the LED is red, the Synth driver is available, but currently closed.  You should not hear synthesized audio at this point.
	When the LED is red with a black diagonal line through it, the Synth driver is closed, and cannot be opened.  This is usually caused by the WAVE driver being opened when the Mix WAVE/Synth  checkbox is cleared.  It also occurs if the Printer Only radio button is selected in the Advanced Control section of the Audio Control Panel.
