What makes Audacity unique?
- Audacity
is free and the source code is available
under the GNU General Public License.
- Audacity
is cross-platform - it runs on Windows,
MacOS, and many Unix platforms, including Linux.
- No limits on the number of tracks or the length of any track,
except the size of your hard disk.
- Import almost anything: WAV, AIFF, Next/AU, IRCAM, MP3, and
MIDI files are supported natively, but
Audacity
will also open just about any uncompressed sound file and
automatically deduce the format (using the
Import Raw Data...
feature).
- Audacity
acts like a non-destructive editor, providing
multiple levels of undo, but it also writes changes made to the
audio to disk, eliminating the need for complicated real-time
processing.
- Label tracks allow you to annotate waveforms (for example,
transcribing speech) and later export the waveforms to a text file.
- Powerful spectral features allow you to view waveforms as
spectrograms or plot the power spectrum of any region of audio,
and even export this data to a spreadsheet.
