Description
i encode and decode a wav or pcm file with 16khz sample rate.
the result pcm of opus_demo binary by opus source code contains all frequency information between 0-8khz.
the result wav of opusenc opusdec binary by opus-tool contains frequency information between about 0-7.5khz.
why there is difference for the output audio's frequency information ?
thanks.
