RMixer ActiveX allows an easy, comprehensive and reliable control of Playback and Recording of a system Sound Mixer device. This component was created with developer in mind, being pricewise acceptable, reliable, having all necessary features and extremely easy to use.

Access and Control of Playback and Recording lines is achieved through selection of the source line of specified type (Microphone, Line In etc.). Many mixers support Multiplexer (MUX) for recording line - choosing one of several sources, as well as Mixertype for playback line - mixing several sources together, therefore these are correctly supported in any combination or platform.
RetainValues is a quite useful feature to optionally keep specified properties (Volume, Mute and Selection) unchanged while application is running, even when other process makes attempt to change them.
Another feature is to reflect whether Full Duplex is actually supported with the current mixer. It's not impossible when hardware (sound card) supports Full Duplex while driver does not, or vise versa. FullDuplexSupport property is True when both hardware and software support it, and therefore it's possible to record and playback at the same time.

VRMixer ActiveX supports the following properties:

CurrentMixer (Read-Only) Name of the current system mixer Some systems have more then one mixer available
FullDuplexSupport (Read-Only) True if sound card and driver both support Full Duplex Full Duplex allows playback and recording at the same time
LicensedTo Developer or company name Will be assigned after completing registration
RetainValues Set to True in order to keep current volume, mute and select values unchanged, even if other process tries to change them If you place several VRMixer ActiveXs, please assign this value to True for no more then one of them (otherwise it can cause indefinite competitions).
