I have a Hi-Fi test disk which illustrates one situation in which phase has an audible effect. It has a test which can determine whether your speakers are connected correctly. First it plays white noise through both speakers in phase. If your speakers are connected correctly and positioned sensibly then this sounds as if it is coming from a single source ...

"Out of phase" sound can actually be a lot of different sounds, varying from a little bit out of phase to complete counter phase. Counter phase sound being more or less the acoustic mirror image of the original sound. Separately you can't hear the difference between them, but your microphone can. Long before there were sound cancelling head sets, ...

The most important insight to this is that in communications we do not really encode "bits" instead we encode waveforms, in other words messages are encoded into waveforms not into "bits". Now waveform communications aimed at a specific spatial direction have several "dimensions" that can be used to carry the message. time ...

Any form of digital radio communication already employs error correction. It's not so much a question of whether or not to use error-correction, but an assessment of the amount of overhead to be allocated to provide support for error correction. Such overhead reduces the bitrate of the transmission. Given the state of technology of error correction I would ...

I solved this finally after 2 days of frustration. I still have no idea why this is the way it is so any insight would be great. The solution is to use the phase produced by arctan2(Im, Re) and modify it according to this equation. phase = np.arctan2(sig_fft[j].imag, sig_fft[j].real) formula = ((((wavelength[j]) / 2) - 2) * np.pi) / wavelength[j] ph....
