Perceptual Audio Codecs: What to Listen For

The AES Technical Committee on Coding of Audio Signals has published online a second edition of the invaluable educational resource "Perceptual Audio Codecs: What to Listen For."

The resource aims to offer non-experts guidance on the background and sound of the perceptual effects a listener is likely to be confronted with when working with perceptually encoded, data-reduced audio signals. After several print generations of the original CD-ROMs it was time for an update to include new coding strategies that have become popular. This second-generation material features a number of enhancements:

• New material on advanced coding strategies has been added, partially with exciting interactive displays. Some of the graphics of the original material were enhanced in the same way.
• Audio playback is now seamless and convenient (without needing external player applications) due to the use of HTML5's audio capabilities.
• The material is now provided as a download package (rather than a hybrid CD ROM) and formatted to seamlessly display on modern reproduction devices, such as computers, tablets and mobile phones.
