Fraunhofer l3enc was the first public software able to encode pulse-code modulation (PCM) .wav files to the MP3 format. The first public version was released on July 13, 1994. [ 1 ] This command-line tool was shareware and limited to 112 kbit/s.
For example, LAME was chosen as the representative MP3 encoder because it clearly outperformed four other MP3 encoders on a subset of the full sample corpus.

While there are many MP2 encoders, TooLAME is well-known and widely used for its particularly high audio quality. It has been unmaintained since 2003, but is directly succeeded by the TwoLAME code fork (the latest version, TwoLAME 0.4.0, was released October 11, 2019). The name TooLAME is a play on LAME and Layer II.
An MP3 file can be edited without transcoding. Cut, copy, paste, and volume change operations are provided; edits can be previewed, including a command that plays a segment without a selected region (previewing a cut) Audio normalization and pause detection; MP3 recording with ACM or LAME encoder (not bundled) Fast MP3 visualization
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.
Examples of audio coding formats include MP3, AAC, Vorbis, FLAC, and Opus. A specific software or hardware implementation capable of audio compression and decompression to/from a specific audio coding format is called an audio codec ; an example of an audio codec is LAME , which is one of several different codecs which implements encoding and ...
LAME is the most advanced MP3 encoder. [ citation needed ] LAME includes a variable bit rate (VBR) encoding which uses a quality parameter rather than a bit rate goal. Later versions (2008+) support an n.nnn quality goal which automatically selects MPEG-2 or MPEG-2.5 sampling rates as appropriate for human speech recordings that need only 5512 ...
