Bluetooth supports audio, yet Bluetooth audio requirement and audio specifications are not well defined today. Some parameters are not specified, some parameters are simple "copy and paste" from telephony standards - with no clearly defined references. A reader is sent to study one after another documents that define audio requirement as cleverly as original Bluetooth specification. They are confusing, most often without proper explanation. Even experienced designer may not be able to figure out easily if requirement refers to dBV/Pa or dBPa/mV for example. Audio Scientific has the right expertise in the Bluetooth audio design area and would like to fill such knowledge gap. Thus consider Audio Scientific as your Bluetooth Audio Specialist. We would like to connect every Bluetooth designer with audio resources, so final Bluetooth products provide good voice quality. Nissan Van Parts
