Audio preservation saves memory

Another context of MPAI Audio Enhancement is preservation. Many audio archives urgently need to digitise their records, especially analogue magnetic tapes, because of their life expectancy is short if compared to paper records. International institutions (e.g., International Association of Sound and Audio-visuals Archives, IASA; World Digital Library, WDL; Europeana) have defined guidelines, sometimes only partly compatible, but appropriate international standards are lacking. The Audio Recording Preservation (ARP) use case of the MPAI-CAE standard (CAE-ARP) opens the way to effectively respond…

A standard for “better” audio

Standards for audio exist: MPEG-1 Audio layer II and layer III (so called MP3) and a slate of AAC standards serving all tastes offer efficient ways to store and transmit different types of mono, stereo and multichannel audio . MPEG-H offers ways to transmit and present 3D audio experiences. Never before, if not at the level of company products, however, was there a standard whose goal is not to preserve audio quality at low bitrates, but to improve it or,…

Why an MPAI-CAV standard?

There is a lot of research and experimentation in Connected Autonomous Vehicles (CAVs), but there is not much in terms of standardisation. That should not be a suprise because a traditional approach could well consider CAV standards as premature at this time, and some affected industries may even not be ready yet for such a step. Still standardisation of CAV is needed because of the following reasons: The different nature of the interacting technologies making up a CAV. The sheer…

Connected Autonomous Vehicles in MPAI

For about a year, MPAI has developed Use Cases and Functional Requirements for the Connected Autonomous Vehicles (MPAI-CAV) project, and the document has reached a good maturity. MPAI is now publishing the results achieved so far on this and other web sites, on social networks and newsletters. Moving Picture, Audio and Data Coding by Artificial Intelligence (MPAI) is an international, unaffiliated, non-profit organisation with the mission is to develop Artificial Intelligence (AI) enabled data coding specifications, with clear Intellectual Property…

Conversing with a machine

It will take some time before we can have a casual¬† conversation with a machine, but there is significant push by the industry to endow machines with the ability to hold even limited forms of conversation with humans. The MPAI-MMC standard, approved on 30th of September provides two significant examples. The first is Conversation with Emotion (MMC-CWE) depicted in Figure 1. it assumes there is a machine that responds to user queries. The query can be about the line of…

Celebrating the anniversary of the first MPEG standard

For the first 10 years, the cadence of MPEG meeting was March-July November. In addition to these 3 meetings per year, a number of other meetings were added to cope with the hectic rhythms of development of the first standards. The total number of meetings was 43, which makes about 4 meetings a year. If we consider that MPEG had 130 meetings, i.e., 32 years, until its end in 2020, the average meeting frequency remained constant at 4 per year.…
