FFmpeg codecs in the libavcodec library, e.g. AC-3, AAC, ADPCM, PCM, Apple Lossless, FLAC, WMA, Vorbis, MP2, etc. FAAD2 – open-source decoder for Advanced Audio Coding . There is also FAAC , the same project's encoder, but it is proprietary (but still free of charge ).
opencore-amr (decoder), from OpenCORE (one may compile ffmpeg with—enable-libopencore-amrwb to incorporate the OpenCORE lib) vo-amrwbenc (encoder), from VisualOn, included in Android (one may compile ffmpeg with—enable-libvo-amrwbenc to incorporate the VisualOn lib) FFmpeg (by default decoder only, but see above the compiling options). AMR-WB+
libavresample is a library containing audio resampling routines from the Libav project, similar to libswresample from ffmpeg. libavcodec is a library containing all of the native FFmpeg audio/video encoders and decoders. Most codecs were developed from scratch to ensure best performance and high code reusability.
Free and open-source software portal; libavcodec is a free and open-source [4] library of codecs for encoding and decoding video and audio data. [5]libavcodec is an integral part of many open-source multimedia applications and frameworks.

An audio conversion app (also known as an audio converter) transcodes one audio file format into another; for example, from FLAC into MP3.It may allow selection of encoding parameters for each of the output file to optimize its quality and size.
The quality the codec can achieve is heavily based on the compression format the codec uses. A codec is not a format, and there may be multiple codecs that implement the same compression specification – for example, MPEG-1 codecs typically do not achieve quality/size ratio comparable to codecs that implement the more modern H.264 specification.
The encoder and decoder have been part of the free, open-source library libavcodec in the project FFmpeg since June 2003. [5] FFV1 is also included in ffdshow and LAV Filters, [6] which makes the video codec available to Microsoft Windows applications that support system-wide codecs over Video for Windows (VfW) or DirectShow.
