Abstract
A system determines the position of a sound source with a microphone in a fixed coordinate system. The microphone measures audio signals that are analyzed and processed to determine the position of the sound source in the fixed coordinate system. The system may adjust the direction of the microphone in the fixed coordinate system based on the processed audio signals and the position of the sound source. The microphone direction may be identified through an optical source that may be adjusted based on the processed audio signals and the position of the sound source.
Claims13
A method for receiving audio at a microphone comprising:
- determining a fixed coordinate system
- identifying a position of the microphone relative to the fixed coordinate system, where the microphone includes a plurality capsules;
- receiving audio signals representative of at least one sound source, where each of the capsules generates an audio signal;
- analyzing the audio signals based on the known positions of the microphone and capsules in the fixed coordinate system;
- adjusting a direction of at least one of the capsules based on the analysis of the analyzed audio signals received at that at least one capsule;
- providing an identification of a principal direction of the microphone, where the principal direction of the microphone is known relative to the fixed coordinate system;
- and
- adjusting the identification of the principal direction of the microphone based on the analysis of the analyzed audio signals, where the identification comprises a light source that illuminates a direction of the microphone.
A system for determining a position of a sound source comprising:
- a microphone including a plurality of capsules, where each capsule measures an audio value where the microphone includes a deflector and a measuring stick;
- a sound analyzer in communication with the microphone that receives an audio signal representative of the audio value for the capsules;
- and
- an identification generator in communication with the sound analyzer that comprises a light source;
- where the sound analyzer identifies a location of the sound source with respect to a fixed coordinate system based on the audio signals and the identification generator marks the location of the sound source with respect to the fixed coordinate system and where the measuring stick adjusts an output of the light source and the deflector reflects and directs the light source.
A method of determining a position of a sound source comprising:
- measuring audio from the sound source with microphone capsules that generate audio signals representative of the audio from the sound source, where each audio signal is representative of the audio from a respective one of the microphone capsules;
- generating an identification of a direction of the microphone capsules;
- processing the audio signals to determine the position of the sound source;
- and
- modifying the direction of the microphone capsules based on the determined position of the sound source, where the identification of the direction of the microphone capsules is in the modified direction of the microphone capsules and where the identification of a direction of the microphone capsules comprises a light beam that is shined in the direction of the microphone capsules.
