The present invention provides a method of processing musical information. A user can perform a musical piece, using a real musical instrument (e.g. a guitar), which is received as audio input. The audio input is then assessed to determine whether it meets various quality standards—for example, whether the user played at the right pitch, at the right time, or at the right volume. If the audio input meets the standards, audio output is then provided of a professional performance of the musical piece, such that it sounds as if the user is performing the professional audio. The standards can be adjusted to different levels, depending on the user's skill on the musical instrument. At an easy level, low standards may be applied, such that even unskilled or beginner musicians can sound like a professional. For more skilled users, the standards may be more difficult to meet. If the user does not meet the quality standards, alternative audio output may be provided, indicating incorrect performance of the musical piece.

A music application guides a user with some musical experience through the steps of creating and editing a musical enhancement file that enhances and plays in synchronicity with an audio signal of an original artist's recorded performance. This enables others, perhaps with lesser musical ability than the original artist, to play-along with the original artist by following melodic, chordal, rhythmic, and verbal prompts. The music application accounts for differences in the timing of the performance from a standard tempo by guiding the user through the process of creating a tempo map for the performance and by associating the tempo map with MIDI information of the enhancement file. Enhancements may contain MIDI information, audio signal information, and/or video signal information which may be played back in synchronicity with the recorded performance to provide an aural and visual aid to others playing-along who may have less musical experience. 1. A method of guiding a user through a music application for enhancing a performance signal , comprising:prompting the user to store the performance signal in a performance track of the music application;prompting the user to store information in accordance with the tempo of the contents of the performance track in a tempo track of the music application;prompting the user to store enhancement data that is both associated with the contents of the performance track and temporally linked to the contents of the tempo track in at least a first enhancement track of the music application; andprompting the user to save the contents of the tempo track and the contents of at least the first enhancement track as an enhancement file.260-.

A sound capture device is affixed to an acoustic instrument to capture the natural sound output of the instrument. The captured sound signal is routed to an electronic sound augmentation system that is configured to augment the captured sound with spatial sound effects such as reverb, echo, delay, etc. The processed and augmented sound is then reproduced via a vibrating driver that has been affixed to the body of the acoustic instrument. This creates a situation where the body of the musical instrument, responding to a series of vibrations produced by the vibrating driver, acts as a speaker component, reproducing a rich augmented sound output that comprises the sum of the sound produced by the original sound production capabilities of the acoustical instrument plus the added augmented or enhanced sound effects. 1.

The present invention relates to a method and system for analysing audio (eg. music) tracks. A predictive model of the neuro-physiological functioning and response to sounds by one or more of the human lower cortical, limbic and subcortical regions in the brain is described. Sounds are analysed so that appropriate sounds can be selected and played to a listener in order to stimulate and/or manipulate neuro-physiological arousal in that listener. The method and system are particularly applicable to applications harnessing a biofeedback resource. 1.
