Acoustica MP3 Audio Mixer

  Mix MP3s and create your own custom DJ-style mix CD. Record your own sounds and layer sound effects and music tracks to create your own audio mixes for audio books or radio shows. DJs and online sound pioneers will find this refreshingly easy and fun to create quick sonic compositions. Features include an intuitive drag-and-drop interface, the ability to mix and record as many simultaneous WAV and MP3 files as you want, and complete control over the volume, pan, and playback rate of each individual sound. You can also import playlists (M3U, PLS) to create instant mixes of your favorite songs and export your finished mix as a RealAudio G2 or MP3 file for streaming over the Internet.
Version 2.13 fixes a bug where track lengths were not showing up correctly when importing an old Sound Group into an existing Sound Group (embedded SoundGroup import).
