In the late 1990s, American telephone company Sprint rolled out a marketing campaign highlighting the audio quality of its nascent digital networks. The campaign included the iconic "pin drop" television commercial that featured a sewing needle falling down next to an old-fashioned handset. The message that Sprint intended to convey with this marketing campaign was that wideband audio had arrived to define a new era of telephony in terms of voice quality.
The History of Apple Valley HD Audio
The aforementioned pin drop commercial was introduced in 1987, the same year when a Nokia protocol for wideband audio became a new telephony standard that would later become known as HD voice or HD audio. It should be noted that wideband audio predates the era of Voice over Internet Protocol systems, which means that it started when the Plain Old Telephone System (POTS) was still around.
HD audio is the default setting for modern VoIP calls. If your Apple Valley business migrates from PBX to VoIP, you should expect HD audio; however, there are some requirements to ensure that all your calls will enjoy this quality.
The Function & Benefits of HD Audio
Let's say you connect two computers at your Apple Valley office by means of a crossover Ethernet cable; as long as these devices have the right VoIP client and codecs installed, HD audio calls will be guaranteed. Once you start placing strain on the bandwidth of the ad hoc network set up between the two computers, you could expect some issues with call quality. Let's say you start transferring thousands of files from one computer to the other and vice versa; at this point, you may experience quality-of-service (QoS) issues with the VoIP calls.
VoIP networks need adequate bandwidth to transmit data packets; whenever the network has to handle multiple HTTP, FTP, P2P, and DHCP connections, the QoS may suffer, and the voice calls may sound clipped. HD audio is not affected by QoS, but the overall transmission will be deficient with poor QoS.
