What is a OGG file?
Open-source audio format with quality better than MP3
OGG files is a container for storing audio data. It is similar to an MP3 file, but sounds better than an MP3 file of equal size due to its default setting of using variable bit rates. OGG files may also include song metadata like artist information and track data. OGG audio files are popular mainly because it uses a free, unpatented OGG Vorbis audio compression algorithm and is widely supported by most software music players and some portable music players.
OGG primarily uses ‘Vorbis’ encoding which was created by Xiph.Org (the creators of OGG). However, they can also use other types of audio compression (including FLAC and Speex), but those files won’t be referred to as ‘Vorbis audio files.’ Ogg Vorbis is a fully open, non-proprietary, patent-and-royalty-free, general-purpose compressed audio format for mid to high quality (8kHz-48.0kHz, 16+ bit, polyphonic) audio and music at fixed and variable bitrates from 16 to 128 kbps/channel. Thus, Vorbis audio files are similar in audio quality and reproduction to AAC files, and higher quality when compared to MP3 and WMA files.
