Introduction
Audacity is a free, easy-to-use popular open source audio editor and recorder for Windows, Mac OS X, GNU/Linux, and other operating systems.
Features
Recording
Audacity can record live audio through a microphone or mixer, digitize recordings from cassette tapes, vinyl records, and minidiscs. With some sound cards, it can also capture streaming audio.
- Record from microphone, line input, or other sources.
- Dub over existing tracks to create multi-track recordings.
- Record up to 16 channels at once (requires multi-channel hardware).
- Level meters can monitor volume levels before, during, and after recording.
- Intel Mac support
Import and Export
Import sound files, edit them, and combine them with other files or new recordings. Export your recordings in several common file formats.
- Import and export WAV, AIFF, AU, (Ogg) Vorbis, and FLAC files.
- Import MPEG audio (including MP2 and MP3 files) with libmad.
- Export MP3s with the optional LAME encoder library.
- Create WAV or AIFF files suitable for burning to CD.
- Import and export all file formats supported by libsndfile.

Editing
