Patent number: 9412348Abstract: A resonance tuner receives and digitizes an analog signal in response to a resonance of a structure thereby creating a plurality of time samples. A series of the time samples are buffered upon burst detection. A power spectrum is estimated by computing a Time-To-Frequency-Transform of the series of time samples and a magnitude of each of the resulting frequency samples is squared. At least one subset associated with at least one spectral peak is selected from the frequency samples. Each spectral peak has at least one sample with a sufficient magnitude and being spectrally adjacent to any other sample in another spectral peak by less than a threshold. A fundamental spectral peak is determined in a fundamental subset including a spectral peak with a sample at the lowest frequency greater than zero. The fundamental spectral peak has the sample with the largest magnitude within the fundamental subset.Type: GrantFiled: August 7, 2015Date of Patent: August 9, 2016Assignee: Overtone Labs, Inc.Inventor: David Byrd Ribner

Patent number: 9153221Abstract: Provided are a percussion instrument tuning system and method. A position sensor determines at least one first position of a tuning mechanism of a timpano. A control unit generates a calibration result by measuring a first pitch of the timpano corresponding to the at least one first position of the tuning mechanism and estimates a second pitch of the timpano corresponding to at least one second position of the tuning mechanism from the calibration result.Type: GrantFiled: September 10, 2013Date of Patent: October 6, 2015Assignee: Overtone Labs, Inc.Inventor: David Byrd Ribner

Publication number: 20140182446Abstract: A processor of a tuning apparatus receives a desired fundamental frequency or note and determines a frequency of at least one drumhead of a drum in response to the received desired fundamental frequency or note. An output at the processor outputs a value corresponding to the determined frequency of the drumhead.Type: ApplicationFiled: March 7, 2014Publication date: July 3, 2014Applicant: Overtone Labs, Inc.Inventor: David Byrd Ribner

Patent number: 8759655Abstract: Provided are systems and methods for resonance tuning. A signal is received in response to a resonance of a structure. A frequency or musical note related to an overtone is determined from the signal. The frequency or musical note related to the overtone is selected as a filter mode reference frequency or musical note. A display of frequencies or musical notes from a subsequent signal that deviate from the filter mode reference frequency or musical note by a predetermined threshold is suppressed.Type: GrantFiled: November 29, 2012Date of Patent: June 24, 2014Assignee: Overtone Labs, Inc.Inventor: David Byrd Ribner
