Blue or red pill?


Recommended Posts

Hi,

Temporal micro-structure is a made up phrase for audio. I examined briefly Bob Stuarts AES document -  which is a scan of Sound Board 2015 article - temporal micro structure in audio is stated to be the same as spatial resolution in vision.

 

So spatial resolution is effectively the number of pixels representing an image. In audio - as long as the ADC can capture all the audio information, which it does for delta sigma ADC's, then it has sufficient resolution in the time domain (can capture all frequencies).

 

Again, this is obfuscation, as an attempt to state temporal blur needs to be corrected.

  1. Temporal blur does not exist in ADC's since mid 1990's when the first Delta Sigma ADC's were being used
  2. You cannot correct temporal blur - dispersion.

If temporal micro-structure is not sufficiently defined with clear examples, then any discussion is pointless.

It's going to be interesting coming up with another explanation if mansr hears the differences I (and pretty much everyone else who's taken a listen) do, and yet the ADC captures are identical.

 

But this is jumping the gun somewhat.

Hi,

Not sure what the test will be - but any ADC in your house will be different to anything played through the speakers etc.  from which the ADC was taken from.

 

If it is the difference between the same track played via NAS, PC, or CD transport optical output etc., to a DAC,  then buffering and noise can be the reason for the differences heard. If you cannot ensure that noise and buffering are the same for each source, then differences are possible.
