Patent ID: 7272235

Claim:
A method comprising: receiving a request to play an audio file; determining whether volume normalization parameters associated with the audio file are stored in a media library; if the volume normalization parameters associated with the audio file are stored in the media library: retrieving the volume normalization parameters from the media library; playing the audio file using the volume normalization parameters; if the volume normalization parameters associated with the audio file are not stored in the media library: determining whether volume normalization parameters associated with the audio file are stored in the audio file; if the volume normalization parameters associated with the audio file are stored in the audio file: retrieving the volume normalization parameters from the audio file; playing the audio file using the volume normalization parameters; if the volume normalization parameters associated with the audio file are not stored in the media library and are not stored in the audio file, calculating volume normalization parameters while playing the audio file.
