Founded in 1948, the Audio Engineering Society has been shaping professional audio standards for almost 80 years. We chart its rise and uncover how its standards are developed and acquired.
Metadata tagging is easily overlooked but essential for managing audio assets throughout a production workflow. Here we offer practical guidance on embedding and converting metadata across common audio file formats.
HE-AAC builds on the foundations of AAC to deliver near CD-quality audio at bitrates as low as 32 kbps, making it the codec of choice for mobile TV, digital radio and low-bandwidth streaming. This guide unpacks the key technologies behind its efficiency gains.
AAC succeeded MP3 by delivering better quality at lower bitrates. This guide examines how it works, compares the leading encoder implementations, and explains where it sits within the broader MPEG audio standards landscape.
Launched in 1995, MP3 remains one of the most ubiquitous audio formats in the world. This guide explains how psychoacoustic compression works, explains the differences between MPEG-1 and MPEG-2 implementations, and finds out where MP3 works – and where it doesn’t.
Audio coding demands very different tools and workflows to video, but the same fundamental principles around quality apply to both. This guide surveys the standards, codecs and container formats you need to navigate modern audio workflows.
Effective transcoding has become increasingly critical in the streaming era, with mobile ratcheting up the complexity and range of target platforms even further. The range of options is greater than ever, with cloud, edge, and on premise-based offerings, and multiple combinations of all three.
The launch and growth of YouTube has changed the broadcast landscape both for content creators and for consumers. Today, viewers are no longer tied to the television and broadcasters are embracing multi-channel presentations as more consumers turn to streaming platforms as their first choice viewing destinations.
