REM refers to the font size of the root element (root element,html), from the remote IE6 to Chrome they are all about, the root element of the default font-size is 16px. What about the compatibility of such a new unit? The mainstream versions of Ie9+,firefox, Chrome, Safari, and Opera are all supported, and I can use REM with the audacity. The calculation of EM is based on the parent element, which brings great inconvenience to our calculation in actu

cancellation gain, and so on. For 8000 sample rate, 16bit of audio data, 10ms time sampling point is 80, a sample point 16bit is two bytes, then the data required to pass in Webrtcnsx_process is 160 bytes. For the 8000 and 16000 sample rate of audio data can be used regardless of high-frequency portion, only need to pass in low-frequency data, but for the 32K sampling rate of data must be filtered through the interface data into high-frequency and low-frequency input, the incoming noise reducti
