Good value for money

Works without problems. A few observations:
Why is the help text presented on dark grey background? Looks ugly and makes reading difficult. Help text would benefit from a little better organisation and formatting.
Export graphics seems to be jpg format, but the file has a png suffix. Nice feature, anyway!
Three calibration memories with obviously predefined values. No useful explanation how to calibrate for use with external microphone (with known properties).
Still: a useful tool, and good value for money. Professional users may want to use other (more expensive) apps.
