allows it to run with less than 1% of a CPU core on laptops or even recent phones. Updated: Our paper on FARGAN was accepted in IEEE Signal Processing Letters.
A stereo, surround, and VR extension for EVS is currently being developed under the 3GPP work item 770024. Completion of the resulting Immersive Voice and Audio Services (IVAS) codec, to be standardized in 3GPP specification 26.253, is planned for 2021. Update 2024 That plan had been postponed to 3GPP release 18 in 2024, and the final software release after completion of the standard is now available here.
The OPUS speech and audio codec, as specified in 2012 by the Internet Engineering Task Force in RfC 6716, is an open-source codec with surprisingly good subjective performance which, like FLAC (see above), claims to be free software. Until 2019, the encoder was being regularly improved for better quality, as could be observed here.

Many people never think about where fonts come from, who creates them, or why new ones are developed—fonts tend to be in the background. Yet, they’re an absolutely crucial part of our everyday lives in and out of the classroom. Without fonts, how would we type a paper? Or send a text? How could we even use a calculator?
Just like any other software, big font projects go through a long and complex process (we’re talking years) to become software, from res
