Audacity - audio editing studio is a full-featured, easy-to-use professional audio and music editor for Windows and Mac. The software has clean interface, excellent features and support for 32-bit floating-point audio. Audacity® succeeds at being both feature-rich and flexible, while keeping the toolbar and work space uncluttered. It does this by relegating most functions--such as effects, edits, and project management--to handy drop-down menus. No activation, no expiration date, and no limit on how many computers you can install on.
You can cut, copy and paste parts of recordings and then add effects like echo, amplification and noise reduction. You can also do many extras like : Trim the silence off the beginning and end of audio files. Fade-in and fade-out of music files. Adjust audio volume levels and amplify and equalize effects.
Record Live Audio. Audacity records from any audio source that can be plugged into your computer: live performances, interviews, radio, vinyl records, LP, tape players, microphones, mixers, electronic instruments.
Restore vinyl records, tapes into digital recordings or CDs.
