Audio/video codecs by ACS
Hi there, do you have any detailed information on the audio and video codecs used by ACS when embedded in a website/JS. Including maximum bitrate if possible

Thanks Nikolay,
My understanding is that G.722 offers an audio sample frequency of 16kHz which results in a maximum 8kHz output. SILK, I believe, was as a result of the Skype acquisition in 2011 which created super-wideband audio capable of reproducing 12kHz from a 24kHz sampled frequency.
The exciting part of the MS proprietary "Satin" codec was that whilst it currently provides 16kHz output from a 32kHz sample frequency, it was mentioned that in the coming months this would be increased to provide 'full-band' audio at 48kHz. A standard CD has a 44.1kHz sample frequency, so this update would significantly improve audio output. Currently, competitors such as Zoom are already offering this quality so I'm keen to understand when we can become competitive?

Thanks. We are working on adding more codecs in upcoming quarter. I noted the level of details you want to have in the documentation. We will get these details in docs
