Algorithm for rapidly playing musical instrument through software

Abstract

The present invention provides an algorithm for rapidly playing a musical instrument through software which is concretely applied in the music system development, belonging to the multimedia creation technology field. The algorithm revolves around 'nodes' (notes '0'-'7') in a numbered musical notation and performs data block segment of the numbered musical notation, and each data block has itself music features-pitches and length; a length calculation method is employed to obtain the audio frequency resource s(n) through the relative length r(n, d) of the nodes, the valued-added length a (n, j) of the data block and the basic mode basis of the whole music; the length calculation method is employed to obtain the play time y(n) corresponding to the audio frequency through the delay time spanning t(n, j) and the unit delay time span time of the data block; the length and the rhythm of the whole music is changed through correction of the basis and time values; the feature value of the data block corresponding to each 'node' is [s(n), y(n)]; and finally, a music numbered musical notation is translated to a large data block set [[s(0), y(0)], [s(1), y(1)], ..., [s(0), y(n)]. The development time is saved, the operation efficiency is high, the operation is simple, and the practicability is high.

Description

technical field [0001] The invention relates to an algorithm for quickly playing musical instruments by software, which is specifically applied to the development of music systems and belongs to the technical field of multimedia creation.

Problems solved by technology

[0002] At present, music algorithms mainly focus on music classification, retrieval and recommendation, and there are not many algorithms for music creation

However, most music creation software uses databases to store and manage resources, and has not conducted in-depth discussions on algorithms.

In the existing literature and inventions, there is very little research on this type of algorithm, and the algorithm related to using software to quickly play musical instruments is even blank

[0003] In addition, the development of domestic music creation software is relatively lagging behind. The music creation software market is mostly monopolized by foreign mainstream companies. Domestic related software is uneven and has not formed competitiveness. One of the main reasons is that few relevant Technical Support

Therefore, the threshold for this kind of software development is relatively high, and there are very few researchers engaged in related fields. As a result, there has been a situation of "more music lovers using software and fewer professionals engaged in development". Not many people know how to develop technology
