摘要： Methods, system and/or computer program products for detection of a note include receiving an audio signal and generating a plurality of frequency domain representations of the audio signal over time. A time domain representation is generated from the plurality of frequency domain representations. A plurality of edges are detected in the time domain representation and the note is detected by selecting one of the plurality of edges as corresponding to the note based on characteristics of the time domain representation.

摘要： Methods for generating a new recording of a past musical performance of a musician from a recording of the past musical performance include obtaining a high-resolution data record representing actions of the musician while playing the past musical performance that is generated based on the recording of the past musical performance and positioning an automated musical instrument in a selected acoustic context and a sound detection device at a selected sound detection location in the selected acoustic context. The high-resolution data record is provided to the musical instrument to cause the musical instrument to re-produce the actions of the musician while playing the past performance. Sound waves generated by the musical instrument are recorded while the actions of the musician are being re-produced to generate the new recording of the past musical performance.
