Alpha Microsystems' first product, the AM-100 CPU board The first Alpha Micro computer was the S-100 AM-100, based upon the WD16 microprocessor chipset from Western Digital . In April 1978, the two-board AM-100 was offered at $1,496 (equivalent to $6,984 in 2023).
The acoustic model models the relationship between the audio signal and the phonetic units in the language. The language model is responsible for modeling the word sequences in the language. These two models are combined to get the top-ranked word sequences corresponding to a given audio segment.
Collinear transverse acoustic waves or perpendicular longitudinal waves can change the polarization. The acoustic waves induce a birefringent phase-shift, much like in a Pockels cell [dubious – discuss]. The acousto-optic tunable filter, especially the dazzler, which can generate variable pulse shapes, is based on this principle. [6]
Enhanced Acoustic Simulator for Engineers (EASE) is an engineering design and analysis software for optimizing acoustics. [1] The full product is licensed and copy protected. It can perform complex analysis in three-dimensional space. There is a free-to-use web-based version available for two-dimensional analysis with limited geometry options. [2]
Most of the amplifiers produced by ACC were solid-state, but a few models later in production were valve amps. The company is remembered in particular for its Acoustic 361 bass stack, consisting of an Acoustic 360 bass pre-amplifier and one or two Acoustic 361 W-bins, each featuring a built-in 200-watt RMS power amplifier and a rear-facing 18" Cerwin-Vega loudspeaker.
In some cases, these terms are more precise, as there are various types and causes of echo with unique characteristics, including acoustic echo (sounds from a loudspeaker being reflected and recorded by a microphone, which can vary substantially over time) and line echo (electrical impulses caused by, e.g., coupling between the sending and ...
Mesa-Boogie Mark IV, a guitar combo amplifier. A guitar amplifier (or amp) is an electronic device or system that strengthens the electrical signal from a pickup on an electric guitar, bass guitar, or acoustic guitar so that it can produce sound through one or more loudspeakers, which are typically housed in a wooden cabinet.
Bass combo cabinets and speaker cabinets are typically cube- or rectangle shaped. Some small- to mid-sized combo amp cabinets have a wedge shape, like a keyboard amp or a stage monitor speaker cabinet. The wedge shape, also called a "rock back" feature, enables a bassist to point their speakers up towards themselves, to make it easier to hear ...
