ABSTRACT:
A method, apparatus and computer program product for mixing audio is presented. A plurality of tracks is displayed in a user interface, each track of the plurality of tracks including at least one audio clip. Each audio clip is designated as either a foreground clip or a background clip. The foreground clips are analyzed and loudness corrected. The background clips are analyzed and a distance value between the loudness corrected foreground clips and the background clips is defined. Keyframes are added to some of the audio clips, the keyframes providing a fade between levels of the background clips to take into account the loudness corrected foreground clips and a sequenced audio file is produced from the corrected foreground clips, the background clips and the keyframes.
