In the Thread: What Passes for "Space" in Home Audio?
Post Subject: In the recording.Posted by Bill on: 4/13/2024
Yes, you are correct Paul that the space must be in the recording. Most don't have it, especially multi mike recordings and digital. Analog two mike have the best stereo, especially spaced Omni’s, and digital recordings from analog masters have more than straight digital. Higher bit rate digital original recordings have more than 16 bit.But stereo playback can only give the stage ambiance correctly, not the hall. Hall sound embedded in the best two channel recording usually just muddies the stage ambiance.Only a listening room with correctly placed ambiance( not surround) speakers can give that concert hall feel. Only multi channel recordings, with multiple ambiance channels, or two track recordings holding ambiance information decoded with auro 3d, or to a lesser extent dts or Dolby, can give that feeling of concert hall space.As far as reverberation time, Romy is correct that the recording has to hold the milliseconds of time of the concert hall it was recorded in. Very few do, except multi channel recordings. Romy uses his Yamaha reverberation units to recreate the reverberation time of several concert halls, and I have found a way with my Trinnov prepro using auro 3d and changing the delay timing of the ambiance speakers to mimic the concert hall wall and ceiling response times. The ideal of course would be the ability of a pre pro to do both auro 3d decoding and concert hall reverberation recreation, but there is no prepro available yet to do that.
