By combining biometric data with other sensors GPS, an accelerometer, or an advanced sound processing unit headphones could become a new kind of performance enhancer. 通过把人体的生物体征数据与其它传感器相结合(比如GPS、加速计或者一个先进的声音处理单元(SPU)),耳机还能够提供更多的妙用。
At last, two channel real-time sound intensity sampling and processing ( FFT ) ability is realized in the sound intensity data signal-processing unit. 最终通过软硬件配合,数字信号处理模块实现了对两路声强信号的实时采集和实时FFT变换。
