Glossary of Terms

Advanced Audio Distribution Profile (A2DP) allows high quality audio (stereo or mono) to be streamed from one device to another over a Bluetooth connection.

BlueAnt devices that support A2DP include the BlueAnt S1 handsfree car kit, the BlueAnt Q1 headset, and the BlueAnt M1 stereo speakers.

Audio/Video Remote Control Profile (AVRCP) is a profile that allows Bluetooth devices to remotely control audio and video media on another device. For example, by stopping and starting tracks, and skipping to the next or previous track.

BlueAnt products such as the Supertooth 3 car speakerphone and the T1 headset offer the caller name announce feature: using Text To Speech technology, these devices announce the name of the incoming caller so you do not need to look at your phone to know who is calling you.

Several BlueAnt devices incorporate an advanced Digital Signal Processor (DSP) noise cancellation software solution. The DSP processes the audio data in real time in order to reduce wind noise and other interference, giving you outstanding call quality no matter where you are.

In the context of Bluetooth devices, "duplex" or "full duplex" means that two way communications are possible. Although a half-duplex system would provide communication in both directions, the signal would only be able to travel in one direction at a time (so if someone was speaking to you, you would need to wait until they finish speaking before you could reply.

A full-duplex system provides communication in both directions simultaneously, allowing signals to be sent and received at the same time.

Many of BlueAnt's devices allow you to upgrade the device firmware. This is the software embedded on the device that controls its functions and features.

The Bluetooth Handsfree Profile (HFP) is a specification for communication between Bluetooth devices. HFP is the profile most commonly used to allow mobile phones to communicate with Bluetooth headsets and car kits. HFP provides the ability to carry out basic functions such as answering, rejecting and ending calls, and adjusting the call audio volume, as well as more advanced features like using the phone's voice dial functionality.

The Bluetooth Headset Profile (HSP) is a specification for communication between Bluetooth devices. Compared to the Handsfree Profile (HFP), HSP is a more basic profile. It provides the ability to carry out basic functions such as answering, rejecting and ending calls, as well as adjusting the call audio volume.

If a Bluetooth device supports multipoint it means that the same device can connect to 2 phones or Bluetooth devices at the same time.

For example, the BlueAnt Q1 headset supports multipoint, meaning that you can connect 2 phones to it at the same time. If you receive a call on either phone you can answer it using the headset and the audio will automatically be received through the headset.

Text To Speech technology converts normal language text into synthesized speech. BlueAnt products such as the Supertooth 3 car speakerphone and the T1 headset use Text To Speech technology to announce the name of the incoming caller.

Voice Isolation Technology is BlueAnt's proprietary DSP (Digital Signal Processor) software. It uses sophisticated techniques to separate the voice signal from the background noise using a dual microphone array. This technology is effective against noise sources whether they are stationary, impulsive or even other voices.

Wind Armour Technology is BlueAnt's proprietary wind noise reduction solution. The end result of years of research and development into wind reduction techniques, this solution combines patent-pending design features with BlueAnt's proprietary noise cancellation software to deliver clear audio in wind speeds up to 22 mph / 35 kph.
