Embodiment 1

[0016] A digital audio playback method for synchronously displaying the positions of playing musical instruments. First, establishing musical instrument information data files. The name of each instrument and determine its position when it is played, respectively extract the performance start time, performance end time and performance technique change time of each instrument in the whole track performance process, and then the performance start time, performance time of each instrument The end time and the time when the performance technique is changed are used as the start display time, stop display time and performance technique change display time of the instrument respectively, and the instrument information is displayed according to the instrument’s start display time, stop display time and performance technique change time. musical instrument information data file, the musical instrument information includes musical instrument name or picture pattern, musical instrument s...

Embodiment 2

[0018] A digital audio playback system that synchronously displays the position of a musical instrument, comprising:

[0019] Button or touch screen 109, used to complete various menu operations, information input and function selection;

[0020] The data memory 110 is used to store digital audio files and matching musical instrument information data files. The musical instrument information data files are the performance start time, performance end time and performance technique changes of the musical instruments participating in the performance during the entire repertoire performance. The time is used as the start display time of the musical instrument, the stop display time and the display time of the performance technique change, the musical instrument information data file, the musical instrument information includes the musical instrument name or picture pattern, the schematic position of the musical instrument and the performance technique;

[0021] Display driving mod...

Abstract

The invention discloses a digital audio playing method and a system for synchronously displaying positions of playing musical instruments. The method comprises the following steps of: constructing a musical instrument information data file, namely, determining names of all musical instruments for playing which participate in a play in each chapter according to the a specific orchestration of the chapter and performance conditions, determining the positions of the musical instruments during playing, respectively extracting the playing start time, the playing end time and the time of changing the playing technique of each musical instrument in the whole chapter playing process, taking the playing start time, the playing end time and the time of changing the playing technique of each musical instrument as the start display time, the stop display time and the display time of changing the playing technique of the musical instrument, and constructing the a musical instrument information data file for displaying musical instrument information according to the start display time, the stop display time and the display time of changing the playing technique of the musical instruments, which are the playing start time, the playing end time and the time of changing the playing technique of the musical instruments; and synchronously starting a digital audio file and a musical instrument information data file. The system comprises keys or a touch screen, a data storage device, a display driving module, a liquid crystal display, an audio decoding module, an audio output module and a processor.

Description

technical field [0001] The present invention relates to the technical field of digital audio playback, more specifically, to a digital audio playback method and system for synchronously displaying the position of musical instruments. Background technique [0002] When ordinary non-professionals are listening to music, it is difficult to hear what musical instrument is being played, let alone distinguish where the instrument being played is and what technique is used to play it. At present, there is no audio playback system that can simultaneously display the information of these instruments while playing music. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a digital audio playback method and system for synchronously displaying the position of musical instruments. When the digital audio playback system is playing digital audio, it can The device synchronously displays the schematic position of the musical instr...
