So, G to F sharp, of course, is a semi-tone;the smallest you can get.

所以，升 G 到 F，当然是一个半音；你能得到的最小的。

So, the smallest interval I can recognize is a semi-tone;G to F sharp, back to G again.

所以，我能识别的最小音程是一个半音； G 到 F sharp，再回到 G。

And then that's a Shepard tone C. And then you're hitting all of the F sharps, that's a Shepard tone F-sharp.

然后就是 Shepard 调 C。然后你敲击所有的 F 升音，这是 Shepard 升 F 音。

And if you think about it, any given C is, you know, up from one F sharp and down from another, and all the —one F sharp is up from another C and down from the C. So it's perfectly ambiguous.

如果你想一想，你知道，任何给定的 C 都是从一个 F 升音向上，从另一个升音向下，而所有的升 F 都是从另一个 C 向上，从 C 向下。所以这是完全不明确的。
