This analog process could only capture a limited range of audio frequencies for voices.

这种模拟过程只能捕获有限范语音音频。

So essentially how AI voice generation works is that if you have enough audio of someone talking, it will learn like the actual voice frequencies, the actual like audio frequencies of someone's voice and the way they talk.

AI语音生成基本原理是，如果拥有足够多某人讲话音频，系统就会学习到该人实语音频率、音频频率以及他们说话方式。

Certain audio frequencies like delta waves can help guide your brain into deeper stages of sleep where memory consolidation is its strongest.

某些音频频率，如δ波，能够引导大脑进入更深层睡眠阶段，此时记忆巩固效果最佳。
