The spectral compressor compresses a pre-selected portion of the high frequency band and maps the compressed high frequency band to a lowerband limited frequency range.
频谱压缩器压缩高频频带的预选择部分，并将压缩的高频频带映射到较低的有限带宽频率范围。

In general, a move toward the upper band can often suggest that the asset is becoming overbought, while a move close to the lowerband can suggest the asset is becoming oversold.
通常，向上部布林线移动经常意味这个资产将会被超买，向下部布林线移动则意味将会被超卖。

The extra electron fills up the lower-energy state in the conduction band, causing excited electrons to, effectively, spill over into the higher-energy, photon-emitting state.
