Abstract
An electronic measuring device captures a plurality of audio samples, wherein each audio sample corresponds to a different string of a musical instrument. The device further identifies a plurality of frequency components of each of the plurality of audio samples, calculates an optimal tuning curve based on the plurality of frequency components of each of the plurality of audio samples, and determines a deviation of the plurality of frequency components of each of the plurality of audio samples from the optimal tuning curve.
Claims17
A standalone tuning device comprising:
- a memory;
- and
- a processing device coupled to the memory, the processing device to:
- capture a plurality of audio samples, wherein each audio sample corresponds to a different string of a musical instrument, and wherein the standalone tuning device is applicable to multiple types of musical instruments;
- apply a windowing function to the plurality of said audio samples to create windowed data, the windowing function using a temporal window of a certain size, wherein the certain size varies dependent on an effective frequency of a corresponding audio sample of the plurality of audio samples;
- apply a transform function to the windowed data to identify a plurality of frequency components;
- calculate an optimal tuning curve based on the plurality of frequency components of each of the plurality of audio samples;
- and
- determine a deviation of the plurality of frequency components of each of the plurality of audio samples from the optimal tuning curve;
- wherein the standalone tuning device is a dedicated hardware device for tuning musical instruments.
