FM 这也是一种合成方法,早期的ISA声卡用FM合成来播放MIDI,FM通过声卡用几组振荡器配合来模拟播放MIDI,播放的效果非常差,目前这种FM合成器已经逐渐被波表合成技术取代。PCM PCM即Pulse Code Modulation的缩写,中文意思为脉冲编码调制技术,这是一种音频录制技术,大家可通过PCM将各种乐器演奏的声音录制下来,形成一个音色库,那么当要播放MIDI等乐曲时,如果需要这种乐器的音色,大家通过PCM就能真实地将这个乐器的声响还原出来。这就是波表合成的基础。
FM This is also a synthesis method, the early ISA sound card with FM synthesis to play MIDI, FM through the sound card with several sets of oscillators to simulate playback MIDI, playback is very poor, the current FM synthesizer has been gradually wavetable Synthetic technology to replace. PCM PCM that Pulse Code Modulation acronym in Chinese means pulse code modulation technology, which is an audio recording technology, we can PCM voice recording of various instruments to form a sound bank, so when to play MIDI, etc. Song, if you need the tone of this instrument, we can PCM really be able to restore the sound of this instrument out. This is the basis of wavetable synthesis.
