During the last months I got several complains that the sound produced by "IZ2UUF Morse Koch CW" was garbled and ureadable on some new devices.
It took me quite a while to be able to have a setup showing this problem, because none of my devices had garbled audio and I wasn't having reliable feedback from software simulators. Without seeing (or, better, "hearing") the problem, I had no way to address it.
Well, what I discovered is that somewhere between Android 4.0.3 and 4.2 they broke 8-bit audio support. I switched to 16-bit audio and now it works.
The application (version 1.0.010) can be downloaded as usual from Google Play for free or from my personal website
, for anyone having no access to Google Play.
I would like to apologize with all the people that upgraded their devices and saw their CW training application become useless, I hope they can go back to their training sessions.
