This sample is unique in the collection in that the tone is a higher pitch than the more or less standard 1khz use for most morse code audio files. I'd like to hear more samples/extended audio files of fairly high pitch (but not super audible!) morse code -- something that cuts through lower pitched ambient noise.
niente male il tuo Italiano, Mark! (not bad your Italian!). you're right, I'll make a pack of languages. I wrote my thanks to dobroide in the forum for his excellent idea: it's his fault if all this is rocking!
