RE: How does time-coherent technology correct for lousy recordings?

66.91.178.164

I've not been real successfull explaining this in the past, but i'll try once more. The added distortion is caused by the crossover. A 2nd order crossover slope will add 180 degree's of phase shift, or time delay to what your ears hear. A 4th order crossover will add 360 degree's of phase shift, or time delay to what your ears hear. Another way to look at it is the woofer and tweeter, though starting at the same time, do not STOP at the same time. The original waveform has been altered. That waveform includes the musical nuances of every artist, instrument, recording. For example, you can play an "A" note on a guitar and an "A" note at the exact same frequency on a Ukelele. Do they sound the same? Of course not. The instruments both have their own unique sonic signiture. That individual sonic signiture is there in the original waveform. In fact, if you play the exact same note on a Martin, Takamine and Taylor guitars, they sound different. The sound varies with the type and age of the wood used, the luthiers experience, etc. Phase distortion smears the original waveform in time, thereby also smearing the sonic signiture of every instrument or voice to a degree. The amount of delay varies by frequency. By using a first order crossover, you are not adding that additional phase shift (or time delay) Hence the "poor recordings now sound more listenable" statement. Nothing in the recording has been changed. It's simply that the added phase distorions are not there. Some argue this is not audable, but it clearly is if you listen. What you hear with this design is not that it's a recording of a guitar, as with my own music and studio recordings, but that it's a recording of MY Martin D-28 guitar.
Your hearing deaper into the music.
