A (Amp/Ampere)
The Ampere (abbreviations: Amp or A) is the unit of electric current, or amount of electric charge per second.
AAC (Advanced Audio Coding)
An audio compression scheme defined as part of the
AC (alternating current)
An alternating current is an electrical current whose magnitude and direction vary cyclically, as opposed to DC (direct current), whose direction remains constant.The usual waveform of an AC power circuit is a sine wave, as this results in the most efficient transmission of energy. However certain applications use different waveforms, such as triangular or square waves.
Album art
Album art is a feature of the WAC7500 that displays the artwork (cover picture) of a music album.This display enables the user to quickly identify a music album.The artwork files for music albums can be downloaded from the Internet.

Bit / bits |
| |
A bit is a binary digit, taking a value of either 0 |
| |
or 1. For example, the number 10010111 is 8 |
| |
bits long. |
| |
Bit rate |
| |
Bit rate is the number of bits that are conveyed |
| |
or processed per unit of time.The bit rate is |
| |
usually measured in some multiple of bits per |
| |
second (kilobits per second: kbps).The term |
| |
bit rate is a synonym for data transfer rate (or |
| |
simply data rate). |
| |
Bluetooth® |
| |
Bluetooth® is a |
| |
that is meant to allow mobile devices to share |
| |
information and applications without the worry |
| |
of cables or interface incompatibilities.The name |
| |
refers to a Viking King who unified Denmark. |
| |
Operates at 2.4 GHz. For more information, see |
