Theremin is an electronic tool, patented in 1920 by Leo Theremin. A typical Theremin uses two oscillators – one that generates a static frequency, the other a variable – and amplifies the difference between the two signals, creating sine waves at different frequencies, thereby creating different heights. Theremin uses a secondary circuit to control amplitude. You can control the pitch / volume with your own hands by adjusting the position of the hands relative to the two antennas, making it one of the few instruments in the world that you play without touching!

Theremin是一种电子工具，由Leo Theremin于1920年获得专利。典型的Theremin使用两个振荡器——一个产生静态频率，另一个产生变量——并放大两个信号之间的差异，以不同的频率产生正弦波，从而产生不同的高度。Theremin使用辅助电路控制振幅。您可以通过调整手相对于两个天线的位置，用自己的手控制音高/音量，使其成为世界上为数不多的不用触摸即可弹奏的乐器之一！

Theremin’s tone is well known and can be heard in countless horrors due to his somewhat unnatural and ghostly tone. Theoretically, theremin produces a fundamental tone like a pure sine wave, and pure sine waves sound unnatural because most sounds in nature have overtones. Theremin is considered one of the most complex game tools in the world. It is not only “fretless,” like a violin, but even without strings, and its tone does not just naturally fade, but rather its volume decreases manually. In other words, to get a staccato, you need to control not only attack and hold, but also attenuation. This contradicts the way almost any other tool works.

特里明的语调是众所周知的，由于他有点不自然和幽灵般的语调，在无数的恐怖中都能听到。理论上，特里明产生了一种像纯正弦波一样的基音，而纯正弦波听起来很不自然，因为自然界中的大多数声音都有泛音。Theremin被认为是世界上最复杂的游戏工具之一。它不仅像小提琴一样“无烦躁”，而且即使没有弦，它的音调也不会自然衰减，而是手动降低音量。换句话说，要获得断奏，不仅需要控制攻击和保持，还需要控制衰减。这与几乎所有其他工具的工作方式相矛盾。

In fact, Theremin was the first synthesizer in the world to use electronics to “synthesize” a pure electronic tone. We tried to recreate the sound and feel of this instrument, focusing on such things as portamento and vibrato, since without a properly modeled technique, the Theremin simulator would be a little more than a sine wave generator.

事实上，特里明是世界上第一个使用电子技术“合成”纯电子音调的合成器。我们试图重现这台乐器的声音和感觉，重点放在诸如portamento和颤音之类的东西上，因为如果没有适当的建模技术，Theremin模拟器将比正弦波发生器稍多一些。

Sampling the theremin would be somewhat illogical, since the bulk of the theremin sound is related to smooth portamento / slides. The instrument produces a continuous signal, which can only be reduced in amplitude, but never stops, so when switching from one tone to another, portamento will always be produced if the previous note has not been turned off.

对theremin进行采样可能有点不合逻辑，因为theremin声音的大部分与平滑的幻灯片有关。该乐器产生一个连续的信号，该信号只能在振幅上减小，但不会停止，因此，当从一个音调切换到另一个音调时，如果前一个音符未关闭，则始终会产生portamento。

Our tool seeks to implement most of this behavior. Our tones are generated by purely mathematical sine waves. You can play notes with portamento and you can play more distinct staccato if you let the notes fade out. Amplitude and vibrato can be controlled individually or together using the pitch / / or modulation wheel. Portamento can be set to normal or slow, but portamento speed will decrease or increase depending on the interval being played (closer to portamento notes at a higher speed). Chorus and reverb effects are included and allow you to create slightly different tones.

我们的工具试图实现这种行为的大部分。我们的音调是由纯数学的正弦波产生的。你可以用portamento弹奏音符，如果让音符淡出，你可以弹奏更清晰的断奏。振幅和振动可以单独控制，也可以使用俯仰/或调制轮一起控制。Portamento可以设置为正常或慢速，但Portamento速度将根据播放的间隔而减少或增加（更接近Portamento音符，速度更高）。合唱和混响效果包括在内，并允许您创建略有不同的音调。
