It also has a built-in amplitude envelope editor, a customizable spectrogram mode and a frequency analysis window for audio analysis applications.
Built-in effects include Echo, Change Tempo, and Noise Removal, and it also supports VST and LADSPA plug-in effects.
Changes in Audacity 2.0.4
* Bug fixes for:
- Keyboard Preferences: Shortcuts for Generators, Effects and Analyzers were not exported. All imported shortcut changes were discarded.
- Equalization curves were corrupted in Graphic EQ mode after switching to/from Draw Curves or after running the effect then reopening it.
- Change Pitch displayed corrupted values when reducing pitch or editing "from" Frequency. Detection was very inaccurate at high sample rates.
- Bass Boost no longer clips if the track contains 32-bit audio.
- Auto Duck was excessively slow on older machines.
- (Windows) Exported MP3 comments tags were not seen by Windows programs.
- (Windows and OS X) Audacity crashed if you used system quit before file import was complete.
- Accessibility: ENTER did not toggle selectedness of a label track unless a label was selected.
- Numerous other interface fixes.
* Changes and Improvements:
- New "Reverb" effect to replace GVerb, based on the original "Freeverb".
- New View > Go to Selection Start and Go to Selection End commands.
- New "Align End to End" command to append existing tracks to each other.
- Change Tempo now supports fractional BPM.
- Plot Spectrum now supports FFT sizes up to 65536.
- WAV files now support "Album Title", "Track Number" and "Genre" LIST INFO tags and also support ID3 tags.
- Handle a bug in older iPods or some OS X applications that cause them to refuse AIFF files whose metadata contains an uneven number of characters,
- (Windows) Added support for "Windows WDM-KS" host which can provide very low latencies if you reduce "Audio to Buffer" in Recording Preferences.
- (Windows Vista and later) You can now record computer playback by choosing the new "Windows WASAPI" host in Device Toolbar then a "loopback" input.
- (Windows and Mac OS X): VST scanning dialog now replaced with a dialog for choosing which VST effects to load.
- Modules Preferences replaced with a dialog on launch of Audacity enabling you to choose which modules to load.

Great program that i have been using for the last year or two. Easy to use, with heaps of effects.
The envolope tool is brilliant.
Hats off to the programmers, and anyone affiliated with making this must-have program.

What a great program! The ease of use, the many functions.. You'll be amazed!
If you're just planning on having fun (karoke, recording hilarious songs and sending them to your friends etc), or are in need of editing your old (or new) audio files, this is it!
Thanks a bunch to the guys behind this FREE program :D
Use it to edit your sounds using Cut, Copy and Paste (with unlimited Undo), mix tracks together, or apply effects to your recordings.
