I have just acquired some good re-mastered mono( Re-mastered in mono) jazz albums and while listening I noticed a curious effect. Considering your past examination of the forward-backward listening position I thought It might hold some interest for you. I prefer the far distance position as I have expressed earlier. While listening in my usual position about 14 ft back I had occassion to move forward and I noticed a big improvement in the sound. While sitting back the music had a rather two dimensional soundstage without much prescence; upon moving in, the sound expanded exponentially. The band opened up much wider and instruments appeared more real and lively. Actually it was kind of startling. This may be common I don't know but it is a very noticeable change in ambience. I am talking maybe 4 feet closer.
In cases like this it is usually the recording mic techniques of the mix. There will usually be effects like this that differ from recording to recording. My interest in is general effects that are recording independent as these have implications to the loudspeaker design. Specific effects on a single recording, while interesting and pleasurable, are still quite specific.
Have you ever noiced how the sound of some recodrings "locks in" with at a particular level setting. And how this differes with the recording. I tend to think that this level is the level at which the recording was mixed and the mix just sounds better at that level. This too is not a loudspeaker function however.
Yes I have been following your posts. The thing here is these are all different recordings from different era's dating from 1940's on up to the mid-60's. That was the, what I considered unusual, aspect of that effect. It could be a result of computor re-mastering I don't really know; but the miking is certainly different on every cut of each recording. One or two are live also.
