File Format Information: MP3 (MPEG1/2 Audio Layer 3) is an efficient and lossy compression format for digital audio, offers a variety of different bit rates, an MP3 file can also be encoded at higher or lower bit rates, with higher or lower resulting quality. The quality for stereo is satisfactory to modest requirements at 96 kbit/s in joint stereo mode however, hi-fi transparency demands data rates of at least 128 kbit/s. If the source file is a very large file, it will take more time to upload, be sure to select a valid file. Also, they will be more convenient to share with other people. An MP3 file that is created using the setting of 128 kbit/s will result in a file that is about 1/11 the size of the CD file created from the original audio source.ĪAC supports inclusion of 48 full-bandwidth audio channels in one stream plus 16 low frequency effects channels, up to 16 "coupling" or dialog channels, and up to 16 data streams.
