I'm trying to archive some tapes and while I know what a Spectrum should sound like and can tweak the tone/volume right I'm struggling with the ZX81 (well, the TS1000 specifically) as I acquired these tapes from somebody else.
Can you provide a screenshot of what the WAV manager should look like when loading a good tape? I'm tweaking the two sliders but am not sure what the recording should look like relative to the red and green lines for a successful load.
Also my Tape Source > Audio In is greyed out - any idea why that might be? (I'm currently sampling in Audacity at 44.1KHz/16-bit/mono and then trying the resulting WAV file in EightyOne in TS1000 mode with the 16K pack option set).
Just get your sound file in a Wav file format with a sound capture tool. (the direct sound input can be corrupt by the system sound pooling)
Open the Wav input window, and select the green line (bits volume trigger) to 2/3 of the max higher harmonics volume.
Select the tape converter (tape icon), and check the file in the TZX window.
To create a 'P' file, you need to convert a single file… you had to delete all other one.
If a LOAD"" don't work, you had to use a specific tool (or host wavs files on a backup web site to allow us to fix it).
It can be a little difficult to find the right default values, but you can correct any bit that is interpreted wrong.

I totally agree, Martin. This is a great tool and also is the best at generating wave files, I believe.
