Audio Phasing (Phase Shifting) - Media College
https://www.mediacollege.com/audio/effects/phase-shift/
Phase-shifting, AKA phasing, is an audio effect which takes advantage of the way sound waves interact with each other when they are out of phase. By splitting an audio signal into two signals and changing the relative phasing between them, a …

The key to good opposite sideband suppression with single sideband transmitters using the phasing method rests on the audio phase shifter. Simple audio phase shifters as designed by Dome and Norgaard were able to achieve 40db opposite sideband suppression over the range of 275 to 2750Hz. Beyond this audio base band, sideband suppression rapidly deteriorates and …
Phase shift and its importance in audio amplifiers ...

It's often more useful to work out the phase shifts in terms of group delays : for example a 360 degree phase shift on a 200Hz signal is 5 ms (1 full cycle) and a 1080 degree phase shift would be 15ms. Now consider the speed of sound : about 1000 feet per second, so one way to delay the other signal is to move its speaker back ... 15 feet!

The subwoofer and two-way enclosures have a good overlap in the bass frequencies, however, due to the low-pass filter in the subwoofer amp, there's a phase shift ranging from 60º to 50º in the 0-50 Hz range, the subwoofer being the one "lagging".

Example 1: Left and right channels in phase. But if one side of the stereo signal is reversed, as shown in the second illustration, the signals will cancel each other out. In fact, if we were using a pure sine wave, combining both signals out of phase would result in silence, since the sounds would literally cancel each other out.
Phase - Teach Me Audio

If the same two waves are combined while being completely out of phase by 180 degrees, they will cancel each other out resulting in no amplitude. This is known as destructive interference. When two sound waves with the same frequency but different starting points combine, the resulting wave is said to have a phase shift. The new wave will still have the …

The phase of each channel was in fact different, but the result that mattered to the ear was that the time domain character of the high frequency ENVELOPE was changed from pitchy to flat. In one channel, all was good. In two, the first perception was "HF missing". Then you figure out that it's doing this unpleasant, weird thing.

The audio transformer used after the audio phase shift circuitry isn't critical. I've had success with either a 3k to 3k, 2k to 10k or 1k to 8 ohm. Selectivity isn't brilliant but is better than a direct conversion receiver that has no audio image suppression. You will be able to hear SSB signals 5 kHz apart and mostly separate them.
