OAOD (Audacity)

Application : Audacity

What it is:   Audacity is a digital audio editor and recording
application. Audacity is free, open source and cross-platform,
available for Windows, Mac OS X, Linux and BSD.

Audacity was created by Dominic Mazzoni while a graduate student at
Carnegie Mellon University. Mazzoni now works at Google, but is still
the main developer and maintainer of Audacity, with help from many
others around the world.

Audacity Features:

Some of Audacity’s features include:

Importing and exporting WAV, AIFF, MP3 (via the LAME encoder,
downloaded separately), Ogg Vorbis, all file formats supported by
libsndfile library

WMA, AAC and AC3 via the optional FFmpeg library.

Multitrack mixing

A large array of digital effects and plug-ins. Additional effects
can be written with Nyquist

Amplitude envelope editing

Noise removal

Audio spectrum analysis using the Fourier transformation algorithm

Support for multi-channel modes with sampling rates up to 96 kHz
with 32 bits per sample

The ability to make precise adjustments to the audio’s speed while
maintaining pitch (Audacity calls it changing tempo), in order to
synchronize it with video, run for the right     length of time, etc.

The ability to change the audio’s pitch without changing the speed.

Contains major features of modern multi-track audio software[7]
including navigation controls, zoom and single track edit, project
pane and XY project navigation, non-destructive and destructive effect
processing, audio file manipulation (cut, copy, paste)

Converting cassette tapes or records into digital tracks by
automatically splitting one track into multiple tracks based on
silences in the track and the export multiple option.

Multi-platform: works on Windows, Mac OS X, and Unix-like systems
(including GNU/Linux and BSD), among others.

The latest stable version supports Windows 98/ME/2000/XP/Vista,
but Windows 95 and NT are not supported. Windows 7 support is still
provisional. For Windows 7, the developers recommend the latest 1.3.x
Beta.[8]

Audacity uses the wxWidgets software library to provide a similar
graphical user interface on several different operating systems.

Audacity can also be used for post-processing of all types of audio,
including podcasts. It can be used for finishing podcasts by adding
effects
