The invention discloses a stereo and filter control for a multi-speaker device. A portable electronic device includes at least four speakers spaced apart from one another. An audio processor attenuates a high frequency portion of a left audio signal and a right audio signal to provide a processed left audio signal and a processed right audio signal. An audio router directs the left audio signal to only a first speaker, the right audio signal to only a second speaker, the processed left audio signal to a third speaker, and the processed right audio signal to a fourth speaker. The audio signals may be directed according to the orientation of the device. The cutoff frequency for attenuating the high frequency portion of the audio signals may be responsive to the orientation of the device. In other embodiments, the high frequency portion of the audio signals may be decorrelated to produce signals with high frequency portions for all speakers. 本发明公开了用于多扬声器设备的立体声和滤波器控制。一种便携式电子设备包括彼此空间分离的至少四个扬声器。音频处理器衰减左音频信号和右音频信号的高
