Glossary
The following are some useful technical terms you may need to refer when you use Any Audio Converter.
MP3
MP3(MPEG-1 Audio Layer 3 )is the most popular audio encoding format. It is supported almost all music players. MP3 is a lossy but compressed audio format, so MP3 is quite is much smaller in amount of data required to represent the audio recording. While converting audios to MP3, the lower the bit rate used, the lower the audio quality will be, but the smaller the file size. Likewise, the higher the bit rate used, the higher quality, and therefore, larger the file size the resulting MP3 will be. 128 kbit/s is the most common since it typically offers very good audio quality in a relatively small space. 192 kbit/s is often used by those who notice artifacts at lower bit rates.
AAC
AAC(Advanced Audio Coding) is a standardized, lossy compression and encoding scheme for digital audio. It is considered the successor to the MP3 format by MP3’s creator. AAC is as the default audio format of Apple's iPhone,iPod and iTunes. AAC is also the standard audio format for Sony PS3 and MPEG-4 video. AAC generally achieves better sound quality than MP3 at the same bitrate, particularly below 192 kbit/s.
OGG
OGG is an open standard for a free container format for digital multimedia, unrestricted by software patents and designed for efficient stream and manipulation. Ogg's various codecs have been incorporated into a number of different free and proprietary media players, both commercial and non-commercial, as well as portable media players from different manufacturers. The Vorbis used in Any Audio Converter handles general audio data at mid- to high-level variable bitrates.
WMA
WMA (Windows Media Audio) is the developed by Microsoft and it is the second most widely supported format for compressed audio. WMA files can be played using Zune, PSP, MPlayer, Winamp (with certain limitations — DSP plugin support and DirectSound output is disabled using the default WMA plugin), RealPlayer, and many other media players.
