Recording difficulties [SOLVED]

[Remzi]

If you think adaptor is faulty,please open a dispute case through ebay.
I'm more than happy to give you a full refund.

I think your datasette is either picking up some noise from fridge,freezer or a power tool while recording or it can't do higher baud rates due to bad capacitor or something.
If you have a disk drive,copy a game to tape using Copy 235.

No need for a refund. I'd rather support your efforts even if it didn't work out for me. It clearly works for others.

I'll keep it around and maybe try a different datasette in the future.

Thanks.Can you post that non working game WAV file?

Here is the wav of the TAP file that works when recorded outside of the datasette and does not work when recorded with the datasette.

If you record this game to tape and back it up after,I might be able to find the culprit with that raw WAV file.
Otherwise I will pass it on to the experts.

Here is a copy of the tap recorded to tape with my datasette through the adapter and then read back in Audacity.

Apologies for the extra at the beginning and end. I forgot how long the playtime was supposed to be.

Edit:

The fun part of this is that this copy fails at different points sometimes. I just got it to get to roughly 50 blocks left to load and it crashed. Rewinding and trying again, it fails to get past the Novaload screen. It's wildly inconsistent.

I also did the same.Here is my backup file.

Yours has so much noise at the begining at the end,in between.
It can be the datasette,creased tape or your PC.For example if you run winvice while recording,it creates noise.

One thing I couldn't understand,yours is 4 minutes and 28 seconds long,the one you posted before is 4.20.Did you clean that TAP?
Can you post the TAP file you used so I can try recording that.

[scyllinice]

I used the same tap file that produced the wav that I posted before. Maybe that's a clue. There has been a couple of times that my datasette has slowed or stopped when rewinding while powered by the adapter, but it doesn't happen consistently (and not at all when powered by my Commodore 128)

I do have another datasette (that hopefully works this time) that I'm going to try. If it does, I'll use that one for recording and the one I'm using now for playback since that part seems to work just fine.

[Remzi]

If the datasette had slow downs during the recording,outcome should be shorter than the original.

[scyllinice]

The NOS datasette came in.

So far so good. It loads my Excaliba copy just fine.

Doing test runs with some of the tap images I have been using seem to be working fine as well.

Oddly enough, the tape that I recorded using my Eiki recorder didn't actually work in the NOS datasette, so this one must be way more sensitive than the Commodore one.

At least I can confirm that your adapter does work just fine with a Data-Master model 5500.

Edit:

I readjusted my 1530 to be able to read the NOS datasette recorded tape. It appears to be working ok, so I think I have my solution.

[Remzi]

That's great news mate.I can mark this topic as solved.

Let me give a warning to the future readers.

If you buy a New Old Stock datasette,don't ever touch the azimuth setting!!!
