Please find enclosed a typical tutorial with perfect explanations 

with easy to understand words, properly pronounced and at the right speed.

Tutorial 2 & 3 should be reedited with a silightly louder voice

 and words well pronounced and at a lower speed for worldwide audience.

Your software is magic, short of the  audio files for Tutorials 2 &3.

Thanks for your thoughts and feedback on tutorial 2 & 3.

We wanted to make the videos relaxed, informal and fun and listen to all the feedback we have got from the Youtube channel

Sorry you are having issues with the audio it is not something that has been feedback before, we will monitor the situation

and review if we get  more feedback about it.
