What is MP3 to AAC Converter?

MP3 to AAC Converter enables you convert MP3 to MPEG4 AAC Audio. Advanced Audio Coding (AAC) is a standardized, lossy compression and encoding scheme for digital audio. AAC generally achieves better sound quality than MP3 at similar bit rates. Now you can enjoy the versatile movies on your MP4 Player wherever and whenever. Simple settings, high speed, and friendly interface.

Easy to use – Just two clicks, everyone can become the master of MP3 to AAC Converter;

MP3 to AAC Converter Support Bit Rate

MP3 to AAC Converter several bit rates are specified in the MPEG-1 Audio Layer III standard: 32, 40, 48, 56, 64, 80, 96, 112, 128, 160, 192, 224, 256 and 320 kbit/s. Additional extensions were defined in MPEG-2 Audio Layer III: bit rates 8, 16, 24, 32, 40, 48, 56, 64, 80, 96, 112, 128, 144, 160 kbit/s. Nonstandard proprietary MPEG 2.5 Audio Layer III: bit rates 8, 16, 24, 32, 40, 48, 56, 64, 80, 96, 112, 128, 144, 160 kbit/s.

AAC’s improvements over MP3: More sample frequencies (from 8 to 96 kHz) than MP3 (16 to 48 kHz); Up to 48 channels (MP3 supports up to two channels in MPEG-1 mode and up to 5.1 channels in MPEG-2 mode); Arbitrary bit-rates and variable frame length; Standardized constant bit rate with bit reservoir; Higher efficiency and simpler filterbank (rather than MP3’s hybrid coding, AAC uses a pure MDCT); Higher coding efficiency for stationary signals; Higher coding accuracy for transient signals (AAC uses a blocksize of 128 or 120 samples, allowing more accurate coding than MP3’s 192 sample blocks); Can use Kaiser-Bessel derived window function to eliminate spectral leakage at the expense of widening the main lobe; Much better handling of audio frequencies above 16 kHz; More flexible joint stereo; Adds additional modules (tools) to increase compression efficiency. These modules can be combined to constitute different encoding profiles.
