What is a “Strobe” Tuner?

Date:2020/3/7 10:35:30 Hits:

Most electronic tuners work by using a microprocessor to analyze the average period of the waveform of a vibrating string, and using LEDs to indicate whether the pitch of the string is higher, lower, or directly equal to the specified desired pitch for that string.

Strobe tuners, on the other hand, are effectively stroboscopes; a mechanical spinning disk with a strobe pattern is backlit by an array of lights (usually LEDs) that flash at a rate related to the frequency of the audio being analyzed. When the speed of the disk matches the rate of the flashing lights, the strobe pattern “freezes,” or stops moving, indicating the pitch is in tune.
Strobe tuners are often hailed as the most accurate type of tuner, with precision as high as 1/10th of a cent.

Virtual versions of strobe tuners are also available, which can also be quite accurate.
