= 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]], [[Audio Interchange File Format|AIFF]], [[AU]], (Ogg) [[Vorbis]], and [[Free Lossless Audio Codec|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.
* Open raw (headerless) audio files using the “Import Raw” command.
* Note: Audacity does not currently support [[Windows Media Audio|WMA]], [[Advanced Audio Coding|AAC]], or most other proprietary or restricted file formats.

=== Editing ===
* Easy editing with Cut, Copy, Paste, and Delete.
* Use unlimited Undo (and Redo) to go back any number of steps.

* Edit and mix an unlimited number of tracks.
* Use the Drawing tool to alter individual sample points.
* Fade the volume up or down smoothly with the Envelope tool.

=== DSP Effects ===
* Change the pitch without altering the tempo, or vice-versa.
* Remove static, hiss, hum, or other constant background noises.
* Alter frequencies with Equalization, FFT Filter, and Bass Boost effects.
* Adjust volumes with Compressor, Amplify, and Normalize effects.

=== Sound Quality ===
* Record and edit 16-bit, 24-bit, and 32-bit (floating point) samples.

* Mix tracks with different sample rates or formats, and Audacity will convert them automatically in realtime.
