Hi,
You had to change the capture level in EO.

XavSnap,

Please clarify your quote, "You had to change the capture level in EO", for me. What is the capture level? What is EO? How should I do it from here? Is the file .wav still buggy?

Do you mean the ZX or the modern computer? Please clarify this quote of yours.

You can connect the "Ear" socket directly on the computer…
To avoid noises and save errors.

May I have a GRAPHICAL representation of how should I set up my hardware for improving the signal from the tape or whatever and to somewhere else other? I only see is text or words!

Thanks,
DesSony

XavSnap,
I make a clarification of my assembly listing from the listing of pokes of yours. Does it look better?

.ORG 16514

LOOPW: NOP
IN A, (7F)
OUT (7F), A
JR LOOPW

.END

Please clarify your quote, "You had to change the capture level in EO
The Hardware capture level is set to around 1 volt on the zx81.
All signals up to this volage level is assume to a high level on the $7F input IRQ.
On Eo you can change this trigger level…

I just expend the harmonics caught (deafened?) by the part of the tape of poor quality tape.

In EO, you can change the voltage level to trap the right signal (the green horizontal line):

Both sliders in the right side can help to expand ou move the 0v level.

Just move the green line to the foot of harmonics signals to capture all of them.

Is OK !
The NOP command is to wait the next signal (only one CPU Cycle).

XavSnap,

Many times, I asked you to draw a graphics hardware setup, you just ignore or avoid my question. What is going on?
