time shift increased amount of sound

A duplicate of the same channel with 0.020 seconds time shift time shift really increased the amount of sound.

I am remixing the stereo version of “Please Please Me” by the Beatles of which the left channel is all instruments. The amount of sound is pretty weak and gain did not improve for it is not a volume problem but one of not enough sound.
Since increasing volume (making the wave taller) was not the answer, I decided to make the wave wider.

I did so by first making a duplicate track. I then applied time shift to the duplicate copy and played both as left channel. I repeated with varying amounts of shift till settling on 0.020 seconds. When I played the combine channel the increase in the amount of sound was tremendous without sounding like cave echo. When I played the right channel (almost all vocal) with the combined left channel the quality of sound is better than before this testing.

I am experimenting how to combine the right channel vocals with the left channel instruments. I have separated all four the vocal type segments into individual clips of each segment type. Did the same for the small amount of instruments. Not sure yet how I will put the various parts together

The end hope is stereo with centered vocals from both channels with instruments on both sides.

Is such time shift a variation of Echo affect?

I think if both copies are about the same amplitude I’d call it a chorus effect.

Closely related to the “flanger” effect, which by curious coincidence is generally attributed to Ken Townsend as the “inventor” while recording the Beatles in 1966, and named “flanger” by John Lennon (extensively used on the album “Revolver”).

Townsend devised Artificial Double Tracking or “ADT.” According to historian Mark Lewisohn, it was Lennon who actually gave the process the name “flanging.” Lennon asked Beatles producer George Martin to explain how ADT worked, and Martin answered with the nonsense explanation, “Now listen, it’s very simple. We take the original image and we split it through a double-bifurcated sploshing flange with double negative feedback.” From that point on, whenever Lennon wanted a Beatles song double-tracked, he would ask for “Ken’s flanger”
