Patent number: 10362199Abstract: An audio capture system for a sports camera includes at least one “enhanced” microphone and at least one “reference” microphone. The enhanced microphone includes a drainage enhancement feature to enable water to drain from the microphone more quickly than the reference microphone. A microphone selection controller selects between the microphones based on a microphone selection algorithm to enable high quality in conditions where the sports camera transitions in and out of water during activities such as surfing, water skiing, swimming, or other wet environments.Type: GrantFiled: August 10, 2017Date of Patent: July 23, 2019Assignee: GoPro, Inc.Inventors: Zhinian Jing, Ke Li, Erich Tisch, Joyce Rosenbaum, Magnus Hansson

Patent number: 10327063Abstract: Protected microphone systems may include one or more dampeners, one or more protective layers, or a combination thereof to minimize the vibration sensitivity of a microphone of the protected microphone systems. The dampeners, when present, may be constructed of a foam material or a thin metal material. The protective layer may be a membrane, a mesh, or any suitable material. The protective layer may be air permeable or non-air permeable.Type: GrantFiled: March 23, 2018Date of Patent: June 18, 2019Assignee: GoPro, Inc.Inventors: Joyce Gorny, Erich Tisch, Mark Hardin, Per Magnus Fredrik Hansson

Publication number: 20190132517Abstract: A camera is configured with multiple microphones to reduce wind noise in audio data collected by the camera. The camera receives motion data, which may comprise data indicating acceleration of the camera, a plurality of video frames received by the camera, or a background level of noise associated with one or more microphones configured on the camera. The camera determines a motion vector from the motion data. The motion vector is parallel to the direction of motion of the camera. The camera selects a subset of one or more microphones in the direction of the motion vector. By recording audio data using the one or more selected microphones, the camera reduces wind noise in the audio data.Type: ApplicationFiled: December 24, 2018Publication date: May 2, 2019Inventors: Erich Tisch, Fabrice Barbier, Scott Patrick Campbell

Publication number: 20190096416Abstract: The present disclosure relates to processing a plurality of audio signals. The method includes receiving the plurality of audio signals in the frequency domain and determining an overall attenuation multiplier based on the plurality of audio signals and an overall lookup table that relates decibel values to different overall attenuation multipliers. The method further includes determining an attenuation vector comprising a plurality of bin-specific attenuation multipliers, each bin-specific attenuation multiplier respectively corresponding to a different frequency bin of the plurality of frequency bins. The method further includes scaling each bin-specific attenuation value in the attenuation vector with the overall attenuation multiplier, and editing each of the audio signals based on the scaled bin-specific attenuation values in the attenuation vector.Type: ApplicationFiled: March 23, 2018Publication date: March 28, 2019Inventors: Joyce Gorny, Erich Tisch, Per Magnus Fredrik Hansson

Publication number: 20180102123Abstract: A camera includes one or more microphone pairs. A first microphone (e.g., a main microphone) is ported to the outside of the camera and captures the desired external audio signal, but may also capture undesired vibrational noise. A second microphone has a similar structure to the first microphone, but is not ported to the outside of the camera. Instead, the second microphone is ported into an enclosed cavity (e.g., 1-2 cubic centimeters in volume). The second microphone may pick up the same vibration excitation and internal acoustic noise as the first microphone but very little of the desired external acoustic sounds around the camera. The unwanted noise can then be removed by subtracting the second audio signal from the second microphone from the main audio signal from the main microphone.Type: ApplicationFiled: October 5, 2017Publication date: April 12, 2018Inventors: Erich Tisch, Fabrice Barbier, Magnus Hansson

Publication number: 20180084358Abstract: An audio capture device selects between multiple microphones to generate an output audio signal depending on detected conditions. When the presence of wind noise or other uncorrelated noise is detected, the audio capture device selects, for each of a plurality of different frequency sub-bands, an audio signal having the lowest noise and combines the selected frequency sub-bands signals to generate an output audio signal. When wind noise or other uncorrelated noise is not detected, the audio capture device determines whether each of a plurality of microphones are wet or dry and selects one or more audio signals from the microphones depending on their respective conditions.Type: ApplicationFiled: September 29, 2017Publication date: March 22, 2018Inventors: Erich Tisch, Joyce Rosenbaum, Magnus Hansson, Ke Li, David Wurtz

Patent number: 9872006Abstract: A camera system includes a first microphone, a second microphone, and a microphone controller. The first microphone and the second microphone are configured to capture audio over a time interval to produce a first captured audio signal and a second captured audio signal, respectively. The second captured audio signal is dampened relative to the first captured audio signal by a dampening factor. The microphone controller is configured to store the first captured audio signal in response to a determination that the first captured audio signal does not clip. In response to a determination that the first captured audio signal clips, the microphone controller is configured to identify a gain between the first captured audio signal and the second captured audio signal representative of the dampening factor, amplify the second captured audio signal based on the identified gain, and store the amplified second captured audio signal.Type: GrantFiled: December 30, 2016Date of Patent: January 16, 2018Assignee: GoPro, Inc.Inventors: Paul Beckmann, Erich Tisch, Zhinian Jing
