1,增加了歌词搜索的自主性,用户可以选择自定义搜索关键字,也可以自定义是否和歌词文件相关联,这里的关联并不是把歌词写入歌曲文件,而是在程序中建立一种关联,以免每次播放这首歌的时候都去搜索歌词,而是直接去读取关联好的歌词文件. 2,增加了指定歌词的搜索目录,指定歌词的保存目录功能.为了性能考虑,歌词的搜索目录不会往下递归,只搜索设置的那一级目录. -1, an increase of the autonomy of the lyrics search, the user can select a custom search keyword, but also can customize it and lyrics files, link here is not to write songs lyrics files, but in the process of establishing a linked so as not to play this song every time the time to search for the lyrics, but a direct link to read the lyrics a good document. 2, an increase of the designated search lyrics directory, specify the directory function of the preservation of the lyrics. to performance considerations, the lyrics search directory recursion is not down, it only set up a search directory.

G.723.1优化代码 纯C代码优化，性能不错，编码解码算法都包含；有针对TI平台和windows的工程和测试用例

音乐，电子音乐合成。12分律 1.在钢琴演奏中G音的和弦我们常用G7和弦.不用G和弦.为什么?  2.在乐理中G7和弦5724组成音中2音省略只用574为什么?(和声学中五级七和弦省去第五音) 在12平均律中音的频率 G4=392.00Hz B4=493.89Hz D4=293.66Hz F4=349.23Hz  在纯律中音的频率 G4=396.00Hz B4=495.00Hz D4=293.33Hz F4=352.00Hz  在纯律中D音二个的频率.一个由G和弦产生297.00Hz另一个由Dm和弦产生293.33Hz  G4=396 D=396x3/2/2=297 (钢琴无这个频率)  A4=440 Dx3/2=440 D=293.33 (5度相生律.12平均律.纯律皆D=293)  当前G和弦 D4音=293.33Hz故不会合谐.当D4音=297Hz 才会合谐所以G和弦不会合谐  G7和弦才会合谐.因此有经验的作曲家在配合弦时常用G7和弦而不用G和弦.
