今天去VLSI网站转了一下,发现VS1053B已经可以进行FLAC解码了,目前支持24bit采样率为48kHz的格式。不过有个缺点就是送数据的时候需要比同格式的WAV更快的速率,原文如下
Because of the high data rate, the requirements for data transfer are much higher than for
lossy codecs. Because of compression, audio buffer being shorter than the default FLAC
block size, and some design choices in the FLAC format itself, the peak data transfer
rate must be even higher than the sustained data rate required for uncompressed WAV
files.
有兴趣的朋友可以去VLSI的官网看看。 |
