Recording sound effects to ISD1760
« on: February 22, 2014, 04:00:15 PM »
Hi,I cant find ISD1790 but have ISD1760. I calculated sounds effects from tgis page http://www.lasertagparts.com/mtsounds.htm 
and lenght a lot of this  sounds are 45sec. But the Sound Programmer v7/v8 record to my Isd1760 only 19 orders.Question: why only 19 orders?19 orders it just only 39sec but ISD have free space on memory 60-39=21sec,why I need to use only ISD1790?(That is more expensive)

That's just the way that Jim did it. You can find ISD1790 reasonably priced at:
http://www.aliexpress.com/item/Free-Shipping-5PCS-ISD1790PY-1790PY-ISD1790-DIP-28/1648370727.html
or any other search for them on Aliexpress.
If you want to spend money for the real thing look at:
http://www.digikey.co.uk/product-detail/en/ISD1790PY/ISD1790PY-ND/969420

I've had mixed results from Aliexpress recently. Some chips failed to program. But failed chips vs. Digikey prices I am up!

Hello
I did the same calculation and thougth the sounds should fit the ISD1760 as well. So I programmed and from what I heard it seems to be fine. But I couldn't try all the sounds in game, because I don't have all the devices that trigger thise sounds? Do you? Or you reproduced the sound via software while programming?
I think I'm using programmer v7 ( the old one that was on the website)

Hi Ale,
   I'm not sure if I understand you properly, but you can trigger all the sounds to be played from the ISD by using the buttons at the right hand side of the application.

Thanks : )
Don't know why I wasn't sure that method was enough to verify a proper recording... now the problem is that I don't remember if I did it. At the mooment at least the sound of fire, no ammo, recharge, near miss, hit and dead do work... I'll check for the others asap
Sorry for confusing eventually

If you want to use ISD1760 you can't hear the sounds more than 19 orders unfortunately
But nobody can't tell me  a reason(

If you work out the numbers you are right. The total time of all the samples is well below the capacity of the ISD1760 and so it should fit. However, it seems more than coincidental that the last 30% of the samples fail to record, when the ISD1760 is 30% smaller than the ISD1790.

Maybe the CORE code splits the sample storage so that it uses the entire chips memory, meaning that there are gaps in between each sample. I could only see this being useful if you wanted to change a sample in the middle to a longer one, but not have to re-write the code to change the addresses of subsequent samples.

Damn! True story, you lose the last sounds with isd1760, strange considering the calculations about capacity. One thing can try I guess is to change 39k resistor value that canghes recording bitrate, and maybe space required. don't know : (

Btw Berk, Aliexpress it's quite a jungle... what seller do you by from?

Recording sound effects to ISD1760

Depends on what the OP is looking for. Im not sure that the MBV sound is reverse reverb, as much as it is a more fragmented series of early reflections on the SPXs reverse gate setting.
