I remember that when I posted that a difference in digital recording for the better was that bass range can be recorded stereo due that digital has no limitation as analog that always needs the bass range mono and you posted that even that it could be that way normally digital comes in mono too due that the cost goes to high and in the other side engeeners are a little lazy to do it in the rigth way.
I missed this earlier.
@rauliruegas Emphasis added. This is a common myth. Tape is analog and does not need any mono bass. The reason it can show up on LP is to save time but you don't need to do that if you simply spend time with the project and look into ways to prevent out-of-phase bass from knocking the stylus out of the groove.
There's a number of ways to do that: rest set the groove depth to be deeper, perhaps cut the passage or project about 1dB lower- that doesn't sound like much but 3dB doubles the amount of modulation in the groove so 1dB less modulation can have an enormous effect!.
FWIW where this is really a problem if you are in a hurry to master the LP is below 80Hz- in most rooms its of no consequence. At that frequency the bass note is 14 feet long, and it takes several iterations of the bass note for the ear to know what the bass note is- by that time, the bass in most rooms is entirely ambient so mono bass is inaudible. Subwoofers take advantage of this fact all the time. At any rate the processor that does the mono bass is a passive device. Our processor (which we found we never used) would mono the bass only for a few milliseconds.
So when you are commenting about these things, its best to be informed- keep this in mind with future posts.
