Any resampling, truncation or DSP in the middle (EQ, cross-over, effects, etc) will obviously negate that. Strict definition is same bits as in the content file reaching the DAC. Since everybody's talking about EQ APO, I wanted to understand the reasons of the hype.īut if it by design it can't guarantee bit-perfect input, then.Įasier to understand if you separate out the different concepts/systems.ġ. Method 2 seems unstable for various reasons, which leaves only method 3. So I'd have to resort to an external software (methods 2 and 3 in my OP). I wish I could use the same player with an integrated PEQ, but I can't, because my sound is multichannel and there aren't any multichannel PEQ plugins for foobar2000 (I've searched a lot : only stereo ones). It works well but it's not handy, because every time I want to modify the EQ parameters, I have to create a new impulse response file with Audacity + a VST PEQ. To better undersand my options, right now I'm using a player (foobar2000) with an integrated convolution plugin. What I don't understand is if some Windows settings still allow to keep the sound as "bit-perfect" before it reaches the APO.īecause if that's not possible, then I must confess that I won't understand why EQ APO is so popular among audio enthusiasts (besides the fact that it's free), if by design it can't guarantee bit-perfect input before it even starts EQing the sound. I'd just like to understand the inner works of all this, precisely. I don't care about subjectively hearing a difference or not.
