Embodiment Construction

[0023] Linear predictive coding is a tool mainly used in audio signal processing and speech processing to represent the spectral envelope of digital speech signals in a compressed form based on the information of the linear prediction model. The invention provides a music synthesis method and system based on linear predictive coding.

[0024] refer to figure 1 , the music synthesis method in an embodiment, comprises the following steps.

[0025] S110: Obtain sound information to be synthesized.

[0026] The sound information to be synthesized refers to information that needs to be synthesized into music, including voice information, text information, and the like. Acquiring the voice information to be synthesized may be pre-stored, or obtained by collecting sound through a microphone, or obtained by obtaining input text information.

[0027] S130: Acquire corresponding linear prediction coefficients according to the sound information to be synthesized.

[0028] Linear Pred...

Abstract

The invention relates to a music synthesis method and a system. The method comprises the following steps of acquiring sound information to be synthesized, and according to the sound information to besynthesized, acquiring a corresponding linear prediction coefficient; according to the linear prediction coefficient, acquiring a linear prediction filter of the sound information to be synthesized; receiving music input information, and according to the music input information, acquiring music information to be synthesized; and according to the music information to be synthesized and the linear prediction filter, carrying out coding and synthesis and acquiring synthesized music. For the sound information to be synthesized, the corresponding linear prediction coefficient only needs to be acquired so that the corresponding linear prediction filter can be acquired and is taken as a sound production model. Compared with a traditional method of adopting a wavetable file, by using the method ofthe invention, an audio wave property file does not need to be stored and the sound information to be synthesized and the music information to be synthesized can be effectively synthesized, a storagecapacity can be effectively reduced and simultaneously music synthesis efficiency is increased.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a music synthesis method and system. Background technique [0002] Music synthesis is a method of generating and modifying sinusoidal waveforms and superimposing them for playing music through sound generators and speakers. [0003] The traditional music synthesis adopts the method of wavetable synthesis, by pre-recording all the sounds (including various ranges and tones) that various real musical instruments can emit, storing them as a wavetable file, and replaying them according to the sound recorded in the music file. For music information, the corresponding sound information is found out one by one from the wave table file, synthesized by the microprocessor on the sound card or the processor of the computer system, and released after processing. However, since the wavetable file needs to store the audio waveform file, a complete cycle of a waveform needs to be recor...
