What is
WMA?
Short for Windows
Media Audio, a Microsoft file format for encoding digital audio files similar
to MP3 though can compress files at a higher rate than MP3.
WMA files, which use the “.wma” file extension, can be of any size compressed
to match many different connection speeds, or bandwidths.
Additional information is available on Microsoft
Windows Media page.
What is
M4A?
Because of its exceptional performance and quality, Advanced
Audio Coding (AAC) is at the core of the MPEG-4,
3GPP and 3GPP2
specifications and is the audio codec of choice for Internet, wireless and digital
broadcast arenas. AAC provides audio encoding that compresses much more efficiently
than older formats, such as MP3,
yet delivers quality rivaling that of uncompressed CD audio.
To encode MPEG-4 audio, you need to have River
Past MPEG-4 Booster Pack in addition to your audio software.
