Description

一种可复制音色的自学习电吉他
技术领域
本发明涉及一种乐器领域,具体的说,是一种可复制音色的自学习电吉他。
背景技术
电吉他由于可产生出多变的音色,具有丰富的表现力,而深受广大电吉他手的热爱,经常应用于演出或录音等场合。但是现有的电吉他通常都只具有一种单一的音色,而在实际演出或使用中,往往需要用到多把不同音色的电吉他,这就需要吉他手携带多把电吉他外出,且在演奏的间隙频繁的更换电吉他以匹配演奏所需的音色,既花费时间实际操作起来又相当不方便。
发明内容
为解决上述问题,本发明提供了一种可复制任意电吉他音色的自学习电吉他,通过一把电吉他即可获得多把电吉他的音色,因此使用时不需要频繁更换电吉他。
本发明采用的技术方案为:一种可复制音色的自学习电吉他,包括自学习电吉他琴体、一体式输入/输出接口或者独立的输入/输出接口和补偿装置,所述输入接口连接待复制音色的目标电吉他;所述补偿装置包括模数转换器、数字信号处理器和数模转换器;所述自学习电吉他和目标电吉他分别进行一定时长的弹奏,自学习电吉他通过所述补偿装置分析自学习电吉他琴体与目标电吉他琴体的音色差异,并对自学习电吉他琴体的音色进行补偿,使自学习电吉他的音色与目标电吉他音色接近。
所述一体式输入/输出接口包含一个可切换输入/输出的接口,且可通过按键、旋钮、拨档切换接口输入/输出属性。
其中,自学习电吉他和目标电吉他弹奏的先后顺序可互换。
采用本发明的技术方案,其有益效果为:便于携带,且可复制任意电吉他的音色,使用时不用频繁更换电电吉他,操作简单易行。
附图说明
下面结合附图对本发明的技术方案作进一步说明。
图1是本发明的结构示意图。
图2是本发明的工作原理图。
其中:1.补偿装置;2.输入接口;3.输出接口;A.自学习电吉他;B.目标电吉他;C.音箱或效果器。
具体实施方式
如图所示,一种可复制音色的自学习电吉他A,包括输入接口2、输出接口3和补偿装置1,输入接口2连接待复制音色的目标电吉他B,输出接口3可连接音箱或者效果器C。
其中,自学习电吉他A通过补偿装置1复制目标电吉他音色B包括以下步骤:第一步,对目标电吉他B进行采样学习,目标电吉他B进行一定时长的弹奏,补偿装置1通过学习目标电吉他B的音色,建立以频率响应和包络特征为参数的目标电吉他特征模型;第二步,对自学习电吉他A进行采样学习,自学习电吉他A弹奏和第一步目标电吉他B相同的内容,补偿装置1建立自学习电吉他A本身的以频率响应和包络特征为参数的特征模型;第三步,补偿装置1比对目标电吉他B的频率响应和包络特征与自学习电吉他A本身的频率响应和包络特征,基于二者频率响应和包络特征的差值建立补偿模型,通过补偿模型使得自学习电吉他本身的频率响应和包络特征与目标电吉他频率响应和包络特征的差值最小化。其中,补偿装置1复制目标电吉他B音色的步骤中:第一步与第二步的顺序可互换。
上述实施例仅为本发明的优选方案,并非作为对本发明的进一步限定,不能以此来限制本发明的保护范围,凡是根据本发明精神实质所作的等效变化或修饰,均应涵盖在本发明的保护范围内。
