Output the audio signal (*.bin) with filtering by IIR filter in the SD card using onboard CODEC. For *.wav file, F746_SD_WavPlayer and F746_SD_GraphicEqualiser are published on mbed. SD カードのオーディオ信号 (*.bin) を遮断周波数可変の IIR フィルタを通して,ボードに搭載されているCODEC で出力する.*.wav 形式のファイル用には,F746_SD_WavPlayer と F746_SD_GraphicEqualiser を mbed で公開している.
