Q: When you select a specific string to tune, say the B string, what are the 3 and 2 simbols above and below the B?
A: The superscript shows the octave of note (the normal "A" note is A4) and subscript shows the index of the current string (E6 is the lowest string, E1 is the highest).

Q: What the red arrows mean?
A: When the one of the red arrow lit this means that the note is detuned more than a half note. The arrow displays the direction of the tuning required for the correction of the pitch. Be carefull when using this arrow beacuse it can be false when note detuned by more than an octave (in this case MiniTuner may be measure the harmonics of the note and result can be terribly wrong)

Q: In the audio source setting box what are "line" and "mixer default" for?
A: When "line in" is selected then MiniTuner gets its input from the "Line In" input of sound card (instead of Microphone input). When mixer default is selected then MiniTuner doesn't change the mixer settings.

Q: What is the difference between "Input level" and "Signal level" and what is the meaning of the read and green indications?
A: Input level is the level of the sound which comes directly from the sound card. The signal level is the level of the selected harmonics, the frequency display shows the frequency of this harmonics. If the color of this indicator is red then the level of this harmonics is below the "noise threshold" and the displayed frequency may be incorrect.

Q: What is the Custom windows mixer settings you refer to in the readme.txt file?
A: You can set the input selection and level in the MiniTuner and when MiniTuner starts it activates the settings and restores original settings when exiting.

Q: How do you turn the echo of your microphone off?
A: Use your mixer (eg. mixer of windows). In windows mixer turn off (mute) the microphone input in playback control. But of course check for the microphone is selected in recording controls. To switch between playback and recording settings use the Options/Properties menu.

Q: Which programming language did you use to develop Minituner?
A: C++ (Visual C++ 6.0 Standard without MFC) and my object library.

Q: How do you get tone frequency in Hz?
A: The program uses FFT (Fast Fourier Transformation) of input signal to measure frequency.

Q: When I try to start MiniTuner it says: "Can't open wave device". Any suggestion?
A: Are you sure your wave input is free? And if your sound card not full duplex your wave output is free? Your soundcard capable to sample at 11025Hz, 16bit, mono?

Q: May I get the source of MiniTuner?
A: No.
