Specialized audio equipment is used in specific industries such as the recording industry, and for specialized applications such as voice digitizing and analysis

Antennas are structures or devices used to collect or radiate electromagnetic waves.

PCMCIA cards and accessories follow standards developed by the Personal Computer Memory Card International Association (PCMCIA), an international standards body and trade organization. PCMCIA cards, or PC cards as they are commonly known, were designed originally for adding memory to portable computers, but are now used in a variety of devices.

Audio connectors are used to affix cables to other audio equipment, providing electronic signal transference and grounding protection

Radio frequency identification (RFID) products read or write data to RF tags that are present in a radio frequency field projected from RF reading/writing equipment

Digital audio systems electronically record and store audio signals such as voice, music, alarm, and security messaging for broadcast, editing, monitoring, and playback

Video, audio, and multimedia chips are IC chips designed for video, audio, and multimedia applications

Audio analyzers measure the noise and audio spectrum of output from an amplifier or a stereo

Audio amplifiers and preamplifiers are units that amplify a sound signal, which is then sent to a speaker or another amplifier

Audio switch matrices are electronic switching instruments for interfacing audio signals in scanning, recording and analysis systems

Audio mixers and consoles are units that combine signals from microphones and/or line level sources to produce a combined signal or signals

Audio microphones are designed for sound reception and recording applications (speech and music

Audio recorders / voice loggers are used to locate, retrieve, duplicate and/or distribute audio voice or data information from single system environments to large multi-channel networked systems

Audio transformers are involved in the transmission of voice or sound signals. They often require wide frequency bandwidth with low distortion and noise suppression

RFID edge controllers are semiconductor devices that are located usually at the edge (input or output) of a radio frequency identification (RFID) system. They are used to control all of the inputs/outputs of RFID system devices, and to filter messages
