Microphone Input misinterpreted

I have spend now 3 hours of my practice time trying to set up sightsinging intervals through the microphone with no success.
Of course there is always the possibility that I am simply too stupid, but I think there is a major bug in Earmaster.
I use the mic wizard to set up the mic. And all the pitches are recognized perfectly in the wizard. However, when back to the singing intervals exercise, when I sing (or play) a C4, then it plots a C5 on the staff.
Now when I go back into the mic wizard to correct this by transposing down, then it just gets worse. THere is a BIG bug in your pitch logic for the sight singing. And I really like you to fix this.
I run the latest Earmaster on a Mac under the latest version of OS X. I think you simply plot the mic note an octave high.

Hi,

Perhaps you are not using the same reference for middle C as EarMaster does and use C3 instead of C4, in which case everything would be transposed one octave.

I do use the same reference. It has to do with you tone recognition algorithm. I have a "multitude" of tuners and I know what a C3 sounds like and what HARD frequency it has. I tried different overtone (both, odd, even) and sometimes it snaps to the correct pitch, then back to an octave high. Its unusable the way it is. And very frustrating too.
I'll see if I can find an external mic somewhere, but I never had any mic trouble with my MBP 2011 with any other app.

Are you using the guitar fretboard as the sole instrument interface in EM?

NO, I use the keyboard and the guitar fretboard. But that is NOT the problem.
Let me explain again.
When I go into the Mic tuning wizard and go through the procedure. Then if I play a C4 (on the guitar, or on the keyboard (a Korg M3 through a speaker), or sing a C4, then the little window in the tuning wizard shows ... a C4. I finish the wizard. I hit a C4 (any of the methods described above)... and I get shown a C5 on the staff.
All I want to do is to set up for some sight singing exercise in the range of for example A2 to E4 and thats obviously impossible for two reasons. 1st, EM doesn't allow to set that kind of range (to my knowledge), and the microphone input doesn't work either. So what do I do ?

Hi,

I just did a test with a microphone plugged in via an Alesis IO2 USB soundcard into a Mac Mini, and playing a B2 in GarageBand for iPhone in front of the microphone displays a B2 in EarMaster, so I am a bit puzzled by your issue. The only scenario where tones from the mic input would be transposed is when using the guitar fretboard interface, as guitar tones are always transposed for better visibility on a staff.

Perhaps we could do a screensharing session so that we may try to find a satisfying setting together for your microphone. Please contact our support (See About Us section of website to write us a direct email).
