A system and method for evaluating the sound quality of piano performance combined with music style

Abstract

The invention proposes a system and method for evaluating the sound quality of piano performance combined with music style. The system includes a piano music library, a microphone array recording device, a high-quality microphone recording device, a music database, an expert listening evaluation module, a signal feature extraction module, a sample library, a signal feature analysis module and a sound quality evaluation module. After the system is established, the user only needs to select a piece of music with a preferred style and play it on the piano to be evaluated. The system will intelligently process the collected performance sound signals and output an evaluation score as the evaluation result of the sound quality of the piano performance. The system proposed by the present invention combines music style factors, analyzes various signal characteristics such as space domain, time domain, frequency domain and time-frequency diagram, and intelligently outputs evaluation results during use. Compared with the previous sound quality evaluation methods, The objectivity, convenience, and intelligence are greatly improved, and at the same time, it is more in line with the individual needs of users.

Description

technical field [0001] The invention relates to the interdisciplinary technical fields of music acoustics, psychoacoustics, signal processing, computer pattern recognition, etc., and in particular relates to a piano performance sound quality evaluation system and method combined with music styles. Background technique [0002] With the continuous development of economy and society, people's material living standards have been rapidly improved, and spiritual and cultural aspects have received more and more attention and attention, and the demand has increased day by day. Among them, the art of music is the most contacted aspect in people's daily life, and the piano, as the "king of musical instruments", occupies a large proportion of the art of performing music. Due to the complex structure and wide range of the piano, it is difficult to study and evaluate its sound quality and timbre. At present, the sound quality of a piano basically depends on subjective judgment, that is...

AI Technical Summary

Problems solved by technology

[0006] The purpose of the present invention is to overcome the defect that the evaluation of piano sound quality relies on subjective evaluation and does not consider the style of music, which leads to insufficient analysis, and solves the problem that only a single microphone is used for data collection and lacks the spatial feature analysis of the piano performance sound signal, Propose a piano performance sound quality evaluation system combined with music style, and use a microphone array recording device combined with a performance sound signal acquisition device with a high-quality microphone recording device
