Well, well, well, what a discovery.
They were schedule, my ZEROs, for mid October but I have received them half an hour ago.
First things first: as a music composer I always said composing on headphones meant doubling the work, since when playing back over monitor loudspeakers so many conflicting issues appeared that headphones were finally placed out of the loop when creation was in progress and only allowed for playback.
NOT ANYMORE, thanks to ZERO from Truthear.
I have tested a huge Cathedral Grand Pipe Organ on my astounding Roland Fantom 8 synthesizer by setting the master tuning out from the standard 440.0 Hz (for A4, MIDI note #69) onto 430.6 Hz so as to place 8.0 Hz on the lowest available note, MIDI 0, C-1 by name, and all is beautifully heard.
I simply played A4 (430.6 Hz) with a velocity of 97 and lasting 187 ticks (0 to 479 available) at tempo 60.
Then copied that recording several times and modified each new pasted note with the editor, so as to have a perfectly equal down scale from A4 to A-1 and then from C4 to C-1.
I cannot understand the reason all books I have thoroughly studied with utmost interest for many years dealing with music and human hearing stay that 15 Hz is the lowest note a human being can hear as a continuous, non beating tone.
???? ???? ???? ????
MIDI 0, C-1 at 8 Hz is here, in my ears, clearly heard and perceived as a continuous sound for 187 ticks and is majestic.
Great work from Truthear, congratulations.
And many thanks indeed to AudioScienceReview for the great work done and in progress.
