- INTRODUCTION
- ------------
-
- TwoLAME is an optimized MPEG Audio Layer 2 (MP2) encoder.
- It is based heavily on:
-
- - tooLAME by Michael Cheng
- - the ISO dist10 code
- - improvement to algorithms as part of the LAME project (lame.sf.net)
- - other contributors (see AUTHORS)
-
- TwoLAME should be able to be used as a drop-in replacement for
- LAME (a MPEG Layer 3 encoder). The frontend takes very similar
- command line options to LAME, and the backend library has a very
- similar API to LAME.

- MPEG Audio Layer 2 (MP2)
- ------------------------
- (taken from Wikipedia article on MP2)
-
- MP2 (sometimes incorrectly named Musicam) is a short form of MPEG Audio Layer II,
- and it is also used as a file extension for files containing audio data of this
- type. While it has largely been superseded by MP3 for PC and Internet applications,
- it remains a dominant standard for audio broadcasting as part of the DAB digital
- radio and DVB digital television standards. It is also used internally within the
- radio industry, for example in NPR's PRSS Content Depot programming distribution
- system.

-
- INSTALLATION
- ------------
-
- Standard automake process:
-
- ./configure
- make
- make install
