HD Audio

First and foremost in our engineers’ minds when designing the Glass IP phone was that it had to be the one of the best and clearest speakerphones on the market. A cutting-edge touch screen and thousands of apps don’t mean a thing if the phone sounds awful.

There are two main ways the Glass IP phone sets itself apart from the field when it comes to sound quality:

1. Hardware Echo-Canceling – Echo canceling is vital to good sound quality (especially to the person on the other end of your call). Many phone manufacturers use software for echo canceling. Software echo cancellation has proven time and time again to be unsatisfactory. This is especially true for VoIP. Software running on a PC can’t come close to the quality of hardware echo canceling.

   The Glass IP phone uses a powerful hardware DSP to echo cancel. A DSP, or Digital Signal Processor, is used for sophisticated pattern recognition. This high-speed processor allows us to compare and “cancel” audio much faster than software options. The DSP chip provides or means real-time, clear conversations. Now you will never again hear: "Are you on speakerphone?"

2. Microphone Isolation – One of the major issues affecting audio in an office phone is the isolation of the microphone. If the microphone is too close to the speaker, as in many phones on the market, you are going to have sound quality issues. All the echo canceling in the world can’t fix this microphone/speaker mechanical coupling.

   Second, you need to completely encapsulate the microphone so that no sound leaks in. Simply moving the microphone away from the speaker but not devoting the time and money to properly encapsulate the microphone is a pitfall of many devices.

   Since we designed the Glass IP phone from the ground up, we were able to address both of these issues. This results in one of the best sounding phones on the market today.
