Audacity
Looking for a good all-purpose audio editor? Audacity is an open-source, free audio editor that lets you record, play, convert, and edit audio files. You can convert file formats, edit sounds, mix tracks, and apply effects to your recordings. The program also features a built-in amplitude envelope editor, a customizable spectrogram mode, and a frequency analysis window. Built-in effects include Bass Boost, Wahwah, and Noise Removal, and the app also supports VST plug-in effects.
The 1.3.0b beta version offers improved performance for larger projects and has several new features such as the ability to expand and collapse tracks. However, we recommend using 1.2.4b for maximum stability.
Note: Some antispyware packages detect Audacity as containing Buddy Spy 2.2 spyware. This is a known false positive. According to the developer, the compressed Audacity executable happens to have some of the same byte-sequences as Buddy Spy 2.2, but it’s just a coincidence. See the developer’s Web site for details.
Version: 1.2.4b
