The blue markers measure the pitch relative to the equal temperament. For tones with several strings it is recommended to record only one string while muting the other ones.ĭuring recording two curves will emerge above the spectrum. There is no need for this quality to be maximal, but it should vary smoothly from key to key. in the bass or in the treble, it is possible to force the recognition by clicking the key twice or by hitting the enter key.Īfter recording the EPT displays the quality of the recorded signal. If the key is not correctly recognized, e.g. If you decide to record a certain note again select the corresponding key by a mouse click or by using the arrow keys. The corresponding key will be marked by a green tick. If you use an earphone a successful recording will trigger a brief echo of the same pitch. Please keep the piano key pressed until the red recording symbol disappears and wait until the data has been processed. Above the keys you will see the frequency spectrum with the partials as a red line. The pressed key is recognized automatically. The recording starts whenever the VU meter passes the upper mark and stops when it falls below the lower mark. Select the recording mode and strike all keys of your piano subsequently from the left to the right in order to record the keys.

If you do not use a headphone you should mute the loudspeaker of your device in order to avoid unintended feedback via the microphone. Headphone: Optionally an ordinary headphone will be useful to check the recorded tones. Inbuilt microphones of tablets and smartphones may be used for testing but they may fail at low and high frequencies.
We recommend a low-noise condenser microphone with a linear frequency response. Microphone: To operate the tuner one needs an external microphone of good quality. Hardware requirements and installationĬomputer: The EPT runs on most laptop and tablet computers and even on mobile phones.
