Now that we’ve learned compression techniques, let’s go over the most common audio codecs. MP3: The most common example of lossy audio is MP3. MP3 players became very popular at a certain point in time for their ability to conveniently store thousands of songs. As a format, MP3 is still the most common storage format.

Overview of MP3 Codec MP3 stands for MPEG-1 Audio Layer III. Created in 1994 by the Moving Pictures Expert Group (MPEG). It is a lossy compression, meaning that not all of the original data is preserved after the compression algorithm is finished. MP3 is also based on ideas from the field of psychoacoustics. The idea is that the the

MP3 is a codec developed by the Fraunhofer Institut in Germany for audio compression. MP3 uses a form of acoustics that only saves those signals that belong to the spectrum of sounds human beings are capable of hearing.

MP3 uses 21 for long windows, 12 for short. AAC uses 49 for long windows, 14 for short. Allow option of mid/side encoding for each critical band. MP3 does not allow mid/side encoding on a band by band basis. AT&T PAC does. (Johnston & Ferrera 1992 References) .

The compressed file is decoded and fed to a DAC when you want to listen. 256kbps AAC is equivalent to 320kbps MP3. Who knew? File types like MP3, AAC, and Ogg Vorbis use psychoacoustic compression principle to exploit the limits of human hearing and remove imperceptible parts of the file to reduce its size.

Newer audio compression technologies MPEG-1 Layer-3 has been defined in 1991. Since then, research on perceptual audio coding has progressed and codecs with better compression efficiency became avail-able. Of these, MPEG-2 Advanced Audio Coding (AAC) was developed as the successor for MPEG-1 Audio. Other, proprietary audio compression systems ...
c# - What's the best audio compression library for .NET ...
https://stackoverflow.com/questions/203254/whats-the-best-audio-compression-library-for-net
Preferably the code would be all .NET (C# or VB.NET), but I don't think this is likely. It should either be lossless or relatively lossless (as good as 192 MP3s, preferably), with a compression ratio at least as good as 4:1. I'd prefer a buffer-based API, but a file-based API is OK too. Does anyone know of anything like this?
