FL Studio (formerly Fruity Loops) is a digital audio workstation, developed by Didier Dambrin (also known as 'Gol'), lead programmer of Image-Line Software. Music is created by recording and mixing audio and/or MIDI data together to create a song, which can then be saved to the program's native .FLP (Fruity Loops Project) format. Songs can be exported to a Microsoft WAV or MP3 file compatible with most media players. As the developers like to say, you will be creating wav, mp3 or midi songs or loops only minutes after launching it.
