Wow Bill, thats an amazing piece of work.

That is at least one commercial MIA that I know of recovered.

As for Interrupt, unfortunately these wavs are just files I accumulated from various places so I don't know what they are meant to be.

Great work Bill.

Well done Bill. One down.

What would be read? In normal operation an interrupt is triggered on an edge (can't remember which on). Would not the bit read just reflect if an edge has been detected or not? As an aside, one of these days, when the emulators are up to it, I would love to write a tape loader with music and loading...

Hi all, I have a number of mp3s that I have discovered over the years that I haven't been able to convert. Now might be a good time to see if, as a group, we can do it now. This first list are working mp3s, i.e. that load correctly into a Memotech however I've not been able do that with my setup. Ji...

Here are some calcualtions that might help: The MTX tape routine works by configuring the CTC to interrupt on edge detection. While waiting for the edge, register A is decremented. No of cycles to execute "DEC A ; JP C, -3" - 14. It takes 14 cycles to decrement reg A. 22050 sample rate is 4E6/22050 ...

Hi Lars,

Great that you have a new tool for converting wavs as I still have a number of wavs that I've not been able to convert. I've got some mp3s too which are known to work.

I will dig out the tape format and post it later today. Off for a flu jab now.

That looks great. Can't wait to try it out.

Could the patch be more to do with interrupt driven sound/music? As the VDP interrupt will be different, i.e. 50Hz or 60Hz, the interrupt routine will need changing. I think it's, skip every 6th interrupt. It does mean sound from every 5th interrupt is twice as long. That makes 5 * 20ms = 100ms = 6 ...
