The energy contained in audio signals or sound power level is typically measured in decibels. As audio signals may be represented in either digital or analog format, processing may occur in either domain. Analog processors operate directly on the electrical signal, while digital processors operate mathematically on its digital representation.
In computing, computer performance is the amount of useful work accomplished by a computer system. Outside of specific contexts, computer performance is estimated in terms of accuracy, efficiency and speed of executing computer program instructions. When it comes to high computer performance, one or more of the following factors might be involved:
1.8×10 1: ENIAC, first programmable electronic digital computer, 1945 [2] 5×10 1: upper end of serialized human perception computation (light bulbs do not flicker to the human observer) 7×10 1: Whirlwind I 1951 vacuum tube computer and IBM 1620 1959 transistorized scientific minicomputer [2]
Instructions per second (IPS) is a measure of a computer's processor speed. For complex instruction set computers (CISCs), different instructions take different amounts of time, so the value measured depends on the instruction mix; even for comparing processors in the same family the IPS measurement can be problematic.

The MSC81xx is based on StarCore Architecture processors and the latest MSC8144 DSP combines four programmable SC3400 StarCore DSP cores. Each SC3400 StarCore DSP core has a clock speed of 1 GHz. XMOS produces a multi-core multi-threaded line of processor well suited to DSP operations, They come in various speeds ranging from 400 to 1600 MIPS ...
When it is necessary to capture audio covering the entire 20–20,000 Hz range of human hearing [6] such as when recording music or many types of acoustic events, audio waveforms are typically sampled at 44.1 kHz , 48 kHz, 88.2 kHz, or 96 kHz. [7] The approximately double-rate requirement is a consequence of the Nyquist theorem. Sampling rates ...
Latency refers to a short period of delay (usually measured in milliseconds) between when an audio signal enters a system, and when it emerges.Potential contributors to latency in an audio system include analog-to-digital conversion, buffering, digital signal processing, transmission time, digital-to-analog conversion, and the speed of sound in the transmission medium.
