使用Java进行编曲

## 一、编曲部分 ##

### 1.1一丢丢乐理知识 ###

简单普及下乐理哈，这样便于读谱  
钢琴谱一行分两个部分  
上面一行用右手弹(主奏)；  
下面一行用左手弹奏(伴奏)。

### 1.2 关于节奏 ###

#### （1）、主奏与伴奏中支持输入的35个音符： ####

倍低音：   “1--” ~ “7--”，
    低 音 ：   “1-” ~ “7-”
    中 音 ：   “1” ~ “7”
    高 音 ：   “1+” ~ “7+”
    倍高音：   “1++” ~ “7++”

#### （2）、分别在主奏(.note)与伴奏(.accompaniments)中输入需要自动弹奏的音符 ####

① 每个音符之间用空格隔开(任意多个空格，推荐每个音符包括空格共占用4个占位符，以便主奏和伴奏音符对齐)  
② 输入字符"0"，则会使音长额外延长一倍，可以理解为停顿；  
③ 输入除了上面35个音符以及“0”以外的任意字符不会对弹奏起任何作用；  
④ 如果需要换行填写，则需在上一行的末尾以及下一行的开头都加上空格;

#### （3）、音长里输入每两个音符之间的间隔时长，单位是毫秒(ms) ####

建议输入整片谱子的最短的间隔，其余更长的的间隔可以利用延时加倍解决

### 1.3实例练习 ###

下面是上文中片段2里的一段旋律：  
![image.png][image.png 1]  
（1）确定最小时间间隔

5+5 67 1+2+ 3+4+ //主奏
    5--0 2-0 7-0 00 //伴奏

（2）成品  
将每个字符间加上空格

5+ 5 6 7 1+ 2+ 3+ 4+ //主奏
    5-- 0 2- 0 7- 0 0 0 //伴奏

## 二、编码部分 ##

### 1.创建一个maven项目。 ###

### 2.pom.xml引入相关依赖 ###

<dependency>
                <groupId>cn.hutool</groupId>
                <artifactId>hutool-all</artifactId>
                <version>5.4.3</version>
            </dependency>
    
            
            <dependency>
                <groupId>com.googlecode.soundlibs</groupId>
                <artifactId>mp3spi</artifactId>
                <version>1.9.5.4</version>
            </dependency>

#### 3.编写实现控制台输出的类 ####

package com.zxm.play;
    public class Animation extends Thread {
    
        /**
         * 音符
         */
        private String[] notes;
        /**
         * 间隔时间（单位：毫秒）
         */
        private int times;
    
        public Animation(int times) {
            this.times = times;
        }
    
    
        //设置音符
        public Animation loadNotes(String notes) {
            this.notes = notes.split(" ");
            return this;
        }
    
        //进程方法
        @Override
        public void run() {
            try {
                int times = this.times;
                new Audio("audio/test.mp3").start();
                sleep(1000);
                int no = 1;
    //            System.out.print(no+": ");
                for (int i = 0; i < this.notes.length; i++) {
                    if (notes[i].length() < 1) {
                        continue;
                    }
                    //将【-、+】这两个字符替换成空
                    String n = this.notes[i].replace("+", "").replace("-", "");
                    if (n.equals("\n") || n.equals("\r")) {
                        System.out.print("\n");
                        no++;
    //                    System.out.print(no+": ");
                        continue;
                    }
                    switch (n) {
                        case "0":
                            System.out.print("_");
                            break;
                        case "1":
                            System.out.print("▁");
                            break;
                        case "2":
                            System.out.print("▂");
                            break;
                        case "3":
                            System.out.print("▃");
                            break;
                        case "4":
                            System.out.print("▄");
                            break;
                        case "5":
                            System.out.print("▅");
                            break;
                        case "6":
                            System.out.print("▆");
                            break;
                        case "7":
                            System.out.print("▇");
                            break;
                    }
                    System.out.print(" ");
                    sleep(times);
                }
            } catch (InterruptedException e) {
                throw new RuntimeException(e);
            }
    
        }
    }

### 4.编写mp3播放相关的类 ###

package com.zxm.play;
    
    import java.io.InputStream;
    import java.util.concurrent.ExecutorService;
    import java.util.concurrent.Executors;
    
    import cn.hutool.core.io.resource.ResourceUtil;
    import javazoom.jl.decoder.JavaLayerException;
    import javazoom.jl.player.Player;
    
    public class Audio {
        private static InputStream is;
        private Player player;
        ExecutorService service = Executors.newCachedThreadPool();
    
        public Audio(String path) {
            is = ResourceUtil.getStream(path);
            try {
                player = new Player(is);
            } catch (JavaLayerException e) {
                e.printStackTrace();
            }
        }
    
    
        public void start() {
            service.submit(() -> {
                try {
                    player.play();
                } catch (JavaLayerException e) {
    
                }
            });
    
        }
    }

### 5.编写处理数字谱的类 ###

         */

         * 间隔时间（单位：毫秒）
         */
        private int times;
    
    
        /**
         * 有参构造器
         */
        public AudioPlay(int times) {
            this.times = times;
        }

         * 加载乐谱
         */
        public AudioPlay loadNotes(String notes) {
            this.notes = notes.split(" ");
            return this;

         */
        @Override
        public void run() {
            try {
                int times = this.times;
                new Audio("audio/test.mp3").start();
                sleep(1000);//准备时间
                for (int i = 0; i < notes.length; i++) {
                    if (notes[i].length() < 1) {
                        continue;
