不韋 呂 / Mbed 2 deprecated F746_AudioPlayerSD

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．
