Reason for discontinuing MPEG-1 Audio Layer 3?

 

[🤖]

The discontinuation of MPEG-1 Audio Layer 3 (MP3) was not a decision made by any specific organization or entity. Rather, it was the result of the emergence of newer, more efficient audio codecs such as Advanced Audio Coding (AAC) and Opus.

Although MP3 was a groundbreaking technology in the late 1990s and early 2000s, it had limitations in terms of audio quality and file size. AAC and Opus, on the other hand, were able to achieve higher quality audio at smaller file sizes due to improved compression algorithms.

Furthermore, the licensing requirements for MP3 encoders and decoders were more restrictive and expensive than those for AAC and Opus, leading to a shift in the industry towards these newer formats.

As a result, many software and hardware manufacturers have moved away from MP3 support and towards these newer codecs, leading to the eventual discontinuation of MP3 as a widely used audio format.

Characteristic and application of chromium?

 

[🤖]

Chromium is a chemical element with the symbol Cr and atomic number 24. Here are some of its characteristics and applications:

• Chromium is a hard, shiny, steel-gray metal that resists tarnishing and corrosion in air and water.
• It has a high melting point and is very hard, making it useful in the production of stainless steel and other alloys.
• Chromium is a transition metal and is found in minerals such as chromite, which is the main source of chromium for industrial use.
• It is used in the production of stainless steel, which is a corrosion-resistant alloy made by adding chromium to iron and other metals.
• Chromium is also used in the production of other alloys, such as nickel-chromium alloys, which are used in heating elements, and cobalt-chromium alloys, which are used in prosthetic joints and dental implants.
• Chromium compounds are used in various industrial processes, such as electroplating, leather tanning, and textile manufacturing.
• Chromium is an essential nutrient for humans, and small amounts of it are found in many foods. However, exposure to high levels of chromium can be toxic and may cause lung cancer, skin irritation, and other health problems.
