Intel High Definition Audio (IHDA) (also called HD Audio or development codename Azalia) is a specification for the audio sub-system of personal computers. It was released by Intel in 2004 as the successor to their AC'97 PC audio standard.
An McASP functions as a general-purpose audio serial port optimized for the needs of multichannel audio applications. Depending on the implementation, an McASP may be useful for time-division multiplexed ( TDM ) streaming, inter-integrated circuit sound ( I2S ) protocol, and intercomponent digital audio interface transmission (DIT).
Digital signal processing (DSP) is the use of digital processing, such as by computers or more specialized digital signal processors, to perform a wide variety of signal processing operations. The digital signals processed in this manner are a sequence of numbers that represent samples of a continuous variable in a domain such as time, space ...
Audio Stream Input/Output (ASIO) is a computer audio interface driver protocol for digital audio specified by Steinberg, providing high data throughput, synchronization, and low latency between a software application and a computer's audio interface or sound card. [1]
An L7A1045 DSP chip, as used in several Akai samplers and the Hyper Neo Geo 64 arcade board The NeXTcube from 1990 had a Motorola 68040 (25 MHz) and a digital signal processor Motorola 56001 with 25 MHz which was directly accessible via an interface. A digital signal processor (DSP) is a specialized microprocessor chip, with its architecture ...
AMD TrueAudio is a kind of audio co-processor. Block diagram of HiFi Audio Engine DSP, which TrueAudio is based on. Shows the 56-bit wide MAC unit.. TrueAudio is AMD ' s application-specific integrated circuit (ASIC) intended to serve as dedicated co-processor for the calculations of computationally expensive advanced audio signal processing, such as convolution reverberation effects and 3D ...
Drivers that may be vulnerable include those for WiFi and Bluetooth, [19] [20] gaming/graphics drivers, [21] and drivers for printers. [ 22 ] There is a lack of effective kernel vulnerability detection tools, especially for closed-source OSes such as Microsoft Windows [ 23 ] where the source code of the device drivers is mostly proprietary and ...
For instance, the default device for sound input and output is /dev/dsp. Examples using the shell: cat /dev/random > /dev/dsp # plays white noise through the speaker cat /dev/dsp > a.a # reads data from the microphone and copies it to file a.a OSS implements the /dev/audio interface.
