Questions tagged [aac]

aac or Advanced Audio Codec is a lossy compression and encoding scheme for digital audio.

aac or Advanced Audio Codec creates files with a sound quality at least as good as that of the more well known mp3 format. After its initial release in 1997 it achieved a higher profile when in 2003 Apple announced that it would use aac for its iTunes and iPod products.

Most modern media software under Ubuntu will play back aac sound although some files with Digital Rights Management (DRM) will be troublesome. Encoding is available with several applications including vlc, FFmpeg, faac and NeroAacEnc.

How to edit tags in AAC files?

In the old days, there used to be an EasyTag extension specifically for this purpose. Today there does not seem to be one and EasyTag does not list AAC files in its GUI. Rythmbox issues an error editing AAC files. Is there any other way of doing it?
