通过截断减少采样位深度 [英] Reducing sample bit-depth by truncating

问题描述

我必须将数字音频信号的位深度从24位降低到16位.

I have to reduce the bit-depth of a digital audio signal from 24 to 16 bit.

每个样本仅取16个最高有效位(即截断)等同于进行比例计算(out = in * 0xFFFF/0xFFFFFF)?

Taking only the 16 most significant bits (i.e. truncating) of each sample is equivalent to doing a proportional calculation (out = in * 0xFFFF / 0xFFFFFF)?

推荐答案

我假设您的意思是(in * 0xFFFF) / 0xFFFFFF，在这种情况下，是的.

I assume you mean (in * 0xFFFF) / 0xFFFFFF, in which case, yes.
