Skype invented the Silk audio codec and remodeled the VoIP trade. Silk is an adaptive variable bitrate codec that may seamlessly change from delivering narrowband (eight kHz) speech at ultra-low bandwidth of 6 kbps to supply a near-transparent high quality speech at greater bit charges. After buying Skype, Microsoft began utilizing Silk audio codec in its merchandise. Silk was developed for the dial-up and broadband world. To present nice audio high quality even below excessive packet loss, Microsoft developed a brand new audio codec, Satin, which affords nice audio high quality at a bitrate as little as 6kbps. Last yr, Microsoft began utilizing Satin in Microsoft Teams. Satin is now used for all Teams and Skype two-party calls. Microsoft will roll out Satin for Teams conferences quickly.
Here’s why Satin audio codec is healthier:
Satin is uniquely positioned to compensate for packet loss. Unlike most different voice codecs, Satin encodes every packet independently, so the impact of shedding one packet doesn’t have an effect on the standard of subsequent packets. The codec can be designed to facilitate top quality packet loss concealment in an inside parametric area. These options assist Satin gracefully deal with random losses the place one or two packets are misplaced at a time.Another kind of packet loss, which is much more detrimental to perceived high quality, is the place a number of packets are misplaced in a burst. Here, Satin’s capacity to ship nice audio at a low fee of 6 kbps supplies the flexibleness to make use of a number of the out there bitrate for including redundancy and ahead error correction that helps us get better from burst packet loss.
