Windows Speech Recognition ( WSR) is speech recognition developed by Microsoft for Windows Vista that enables voice commands to control the desktop user interface, dictate text in electronic documents and email, navigate websites, perform keyboard shortcuts, and operate the mouse cursor. It supports custom macros to perform additional or ...
Sound Recorder can record audio from a microphone or headset. In addition, many modern sound cards allow their output channels to be recorded through a loopback channel, typically called "Wave-Out Mix" or "Stereo Mix". Before Windows Vista, Sound Recorder was capable of: Playing the audio files that it has recorded.
Mandatory Integrity Control ( MIC) is a core security feature of Windows Vista and later that adds mandatory access control to running processes based on their Integrity Level (IL). The IL represents the level of trustworthiness of an object. This mechanism's goal is to restrict the access permissions for potentially less trustworthy contexts ...
DirectSound also provides a means to capture sounds from a microphone or other input and controlling capture effects during audio capture. [2] After many years of development, today DirectSound is a mature API, and supplies many other useful capabilities, such as the ability to play multichannel sounds at high resolution. While DirectSound was ...
A pistonphone is an acoustical calibrator (sound source) that uses a closed coupling volume to generate a precise sound pressure for the calibration of measurement microphones. The principle relies on a piston mechanically driven to move at a specified cyclic rate, pushing on a fixed volume of air to which the microphone under test is coupled.
USSR, 1970s. The nuvistor is a type of vacuum tube announced by RCA in 1959. Nuvistors were made to compete with the then-new bipolar junction transistors, and were much smaller than conventional tubes of the day, almost approaching the compactness of early discrete transistor casings. Due to their small size, there was no space to include a ...
Website. vac.muzychenko.net. Virtual Audio Cable is a software product based on WDM multimedia driver that allows a user to transfer audio streams from one application to another. Any application is able to send an audio stream to the input side of a "virtual cable" while a corresponding application can receive this stream from the output side.
Windows Vista includes integrated microphone array support which is intended to increase the accuracy of the speech recognition feature and allow a user to connect multiple microphones to a system so that the inputs can be combined into a single, higher-quality source.
