The EVS Codec: The Movie

I have written before about standards in general (including one that is 2000 years old) in my post Why Do Layout Designers Say "Stream Out"? and the new cell-phone vocoder standard in Cadence and Standards...and A New Codec for Your Phone. Today, the video version of that codec and how Cadence was involved in its development and standardization. Cadence has been a major contributor to standards in the EDA ecosystem: Verilog, which we put in the public domain; LEF/DEF, which we opened up to as part of the acquisition of Coopers and Chyan; OpenAccess, which we gave to SI2 to manage (see my post The OpenAccess Story); and we have been, and continue to be, a major contributor to various standards working groups. For example, see:

• A History of PSS
• IEEE Unified Power Models
• IEEE 1838: Taking Test into the Third Dimension
• Accellera Functional Safety
• and many more

Now, several people who were involved with the new codec from Cadence, Fraunhofer Institute, Qualcomm, and VoiceAge talk about how the new reference EVS codec was developed, tested, and analyzed.

Cadence Leads Proposal at 3GPP and ITU-T to Enable Best-in-Class Low-Power Speech and Audio Codecs

Raj Pawate, Design Engineering Group Director at Cadence, details the work done at Cadence focusing on 3GPP and ITU-T to enable low-power implementations of speech and audio codecs (5 minutes).

VoiceAge Steers Standardization of New Basic Operators and an Alternate EVS Reference Codec at 3GPP

Milan Jelinek, Senior Research Engineer and Project Manager in Speech and Audio Compression at VoiceAge Corporation, talks about the importance of new basic operators and 3GPP’s standardization of a new reference EVS codec (5 minutes).

Standard Proliferation

There always seems to be an XKCD on almost any topic. Standards are no exception!
