  1. 一、音乐合成和MIDI(Musical Instrument Digital Interface)规范 1,          播放MIDI 乐曲的条件:音乐合成: 音高(音阶),音色,响度和时值 音乐合成器:电子琴或专用芯片或一套软件 音乐合成器分:调频音乐合成(1976)(过去:调幅音乐合成)

  2. FM合成器(硬件产生若干正弦波再组合)

  3. 音乐系统框图

  4. 波表合成器(Wavetable) (1984)(存储各种音乐采样,供调用。需大ROM) 简谱编写软件,文件小。 声音包络发生器

  5. 2,MIDI 规范 (1)MIDI的基本术语: MIDI文件包括音符、定时、和16个通道的演奏定义(键、通道号、音量和力度)。 通道(Channels):独立的逻辑合成器。

  6. 音序器(Sequencer):记录,编辑,播放MIDI文件的电子装置或计算机程序。软件有如:Midisoft Studio,Cakewalk,MIDIGraphy等。 乐器(Instrument) 复音(Puyphong) 音色(Tmbre) 音轨(Tack) 合成音色映射器(Patch apper) 通道映射(Channel mapping)

  7. (2)MIDI与多媒体计算机 (3)MIDI 1.0 技术规范(1983)(P45) 五、语音识别
