A computer implemented method for improving audio, comprising processing audio with a combination of wave adjustment tool WAT and a collection of preset settings for adjusting specific harmonic content to specific genres of music. The preset is selected from the group comprising different genres (styles or types) of music; auto-preset; and generic preset. The auto preset value is determined by the metadata which is commonly included in an audio file. In the event there is no match between the preset genre names and the one in the metadata, then the selected preset will be "Generic." This particular genre preset is designed for optimal sound across many genres, making it generic.
