MP3: The most common kind of digital music file. MP3s usually have no usage restrictions. Short for MPEG Layer-3, a digital media standard developed by the Motion Picture Experts Group (MPEG).
AAC: Advanced Audio Coding. It is a newer kind of audio file that has been promoted as a successor to the MP3. It offers higher-quality sound than an MP3, but takes up about the same amount of space. It is the standard choice of audio file for iTunes.
FLAC: Free Lossless Audio Codec. FLAC is a lossless audio compression format. One of its advantages is that it reduces the file size of an audio program by 30 to 40% without sacrificing audio quality. We offer two types of FLAC files through www.resonusclassics.com which are encoded at 16 bit/44.1kHz or studio master 96kHz/24-bit resolution. It should be noted that high resolution 96kHz/24-bit FLAC albums are large files (often in excess of 1GB for a complete album) and this should be taken into account when purchasing or downloading in this format.
24-bit/96kHz Audio: While we offer these files in FLAC format through our own site for all of Resonus's releases, FLAC, ALAC, AIFF and WAV files at this higher resolution are available from the following sites:
All of Resonus Classics' recordings are compatible with both PC and Mac computers. There are a wide range of suitable players available on the internet for both MP3 and AAC files, including iTunes, Windows Media Player and Winamp. FLAC files are not compatible with iTunes or Windows Media Player, but can be played using Winamp or similar. For more information on the FLAC format, please consult http://flac.sourceforge.net.
