I get the sounds numerous ways... I will take a cassette and a cassette play and attach it with a cable into the MIC of the computer... You allow the computer to record the sound and it puts it in a folder.
I will take a MIC plug it into the computer and do my own sounds with my calls.. Again it does the same thing make a link and puts it in a folder.
I will take a Predator calling CD and do the same thing... Insert it into the computer and pull a sound off it and place it in the folder... I have actually taken Randy Andserso doing Austin how CD and loading it.. Then using the computer to edit off the narrative talk and record the sounds of him doing Austin sounds to call coyotes..
Neat thing once you load all this stuff on the a CD. You can pull it out down the road... I did all of this for my Fox Pro Model 38 and my FoxPro FX5.. Recently I took all those CD's and loaded them to my new computer. made a file... Transferred all the sounds to an SDH 32 blank card.. I removed the card with the 25 sounds that came with the factory SD card . Inserted the blank SDH 32 card to my computer.. Pulled all of the sounds... 65 of them... I put the factory ICOtec card up and now have 65 sounds that are ones I pulled free from ICOtec... Some of me doing sounds, some JS, Kirk, Randy Anders Knight and Hale , Burnham...
Now here is the thing... If you really asked me how I did this... I don't really know... I just played around and I did it.
