Architecture Overview

The Volume service

Volume

Volume is an adjustable setting that controls the loudness of the audio at the output channels of the product. Volume can be set to an absolute value or incremented/decremented in single steps. The maximum Volume setting is defined by the VolumeMax Characteristic. The minimum Volume setting is zero.

Volume Limit

VolumeLimit specifies the upper limit of the Volume. Any attempt to set Volume above the VolumeLimit will reset Volume to the value of VolumeLimit. If VolumeLimit is changed, Volume is checked and automatically reduced if necessary. The maximum VolumeLimit setting is defined by the VolumeMax Characteristic.

Balance

Balance is an adjustable setting that specifies the bias in volume between the left and right output channels of the product. Balance can be set to an absolute value or incremented/decremented in single steps. The maximum Balance setting is defined by the BalanceMax Characteristic. The minimum Balance setting is defined by (-BalanceMax) .

Fade

Fade is an adjustable setting that specifies the bias in volume between the front and rear output channels of the products. Fade can be set to an absolute value or incremented/decremented in single steps. The maximum Fade setting is defined by the FadeMax Characteristic. The minimum Fade setting is defined by (-FadeMax) .

Mute

Mute is an adjustable state that determines if the output channels of the product are muted or not. When muted, all output channels of the product are silent.

Volume

The Volume action reports the current master volume setting of the product.

SetVolume

The SetVolume action provides a means of setting the Volume to an absolute value. The minimum value that can be applied is zero. The maximum value that can be applied is determined by the VolumeMax and VolumeLimit settings. If an attempt is made to set the Volume above VolumeMax, an error will be reported. If an attempt is made to set the Volume above VolumeLimit, the Volume will be set to the VolumLimit value and no error will be repoprted.

Volume Inc

The VolumeInc action provides a means of increasing the Volume by 1.

Volume Dec

The VolumeDec action provides a means of decreasing the Volume by 1.

VolumeLimit

The VolumeLimit action reports the current VolumeLimit setting.

Balance

The Balance action reports the current Balance setting.

SetBalance

The SetBalance action provides a means of setting the Balance to a specific value.

BalanceInc

The BalanceInc action provides a means of increasing the Balance by 1.

SetFade

The SetFade action provides a means of setting the Fade to a specific value.

FadeInc

The FadeIncaction provides a means of increasing the Fade by 1.
