DETAILED DESCRIPTION

(4) Referring to FIG. 1, illustrated is a flowchart for depicting steps of a method 100 for simulating a musical phrase, in accordance with an embodiment of the present disclosure. The musical phrase includes a sequence of notes. At step 102, timbral fingerprints associated with a sample library that comprises recordings of a plurality of notes in a plurality of intensities are generated, using a linear predictive coding technique, wherein the timbral fingerprints relate to the plurality of intensities of the plurality of notes. At step 104, an origin intensity for the musical phrase is determined, wherein the origin intensity is one intensity selected from amongst the plurality of intensities. At step 106, each note in the sequence of notes is simulated, by morphing a recording of each note in the origin intensity according to timbral fingerprints of the note in the plurality of intensities, for simulating the musical phrase.

(5) The steps 102, 104, and 106 are only illustrative and other alternatives can also be provided where one or more steps are added, one or more steps are removed, or one or more steps are provided in a different sequence without departing from the scope of the claims herein.

(6) Referring to FIG. 2, illustrated is a block diagram of a system 200 for simulating a musical phrase, in accordance with an embodiment of the present disclosure. The musical phrase includes a sequence of notes. As shown, the system 200 comprises a data repository 202 and a processor 204. The processor 204 is configured to: generate timbral fingerprints associated with a sample library that comprises recordings of a plurality of notes in a plurality of intensities; determine an origin intensity for the musical phrase; and simulate each note in the sequence of notes.
