2014 Loudspeaker Industry Sourcebook 53 VENDOR DIRECTORY W ireless audio refers to audio signals that travel without wires. While the definition is simple, the implications of wireless audio is profound. Wireless audio provides features and conveniences that used to be impossible to consider even with the most elaborate wired systems. Wireless audio uses an RF transmitter to convey an audio signal to a radio receiver (i.e., streaming). The audio data signal, along with other non-audio data, is broadcast as a radio wave. The signal may be directly broadcast from a transmitter to a receiver (e.g., Bluetooth) or through another device (e.g., a router or Wi-Fi) but the end result is the same. As wireless audio continues to grow in popularity, it has been possible for us to compile a directory solely based on wireless audio. As with the other Loudspeaker Industry Sourcebook (LIS) focus categories, we have included brief profiles on each listing. We touch on Bluetooth providers for using smartphones as an audio server to whole-house audio wireless to Bluetooth speakers and Bluetooth for telephony. The companies listed here offer specialties that range from wireless ICs to modules to board-level offerings to software/firmware to finished products. The wireless RF solutions range from proprietary, often in the 2.4-and 5.6-GHz range, to industry standards (e.g., various Bluetooth protocols).
