Methods and Apparatus to Improve Detection of Audio Signatures - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240329186 titled 'Methods and Apparatus to Improve Detection of Audio Signatures
The patent application describes methods, apparatus, systems, and articles of manufacture to enhance the detection of audio signatures.
- The apparatus includes memory, instructions, and processor circuitry to determine time differences of arrival for audio sensors and match them with virtual source time differences of arrival.
- By identifying virtual source locations based on matched time differences, the apparatus reduces computational burden by removing unnecessary audio recordings.
- Key Features and Innovation:**
- Improved detection of audio signatures through time differences of arrival analysis.
- Efficient processing by matching time differences with virtual source time differences.
- Reduction of computational burden by removing redundant audio recordings.
- Potential Applications:**
- Audio surveillance systems for security purposes.
- Audio recognition systems for media content identification.
- Acoustic monitoring systems for environmental analysis.
- Problems Solved:**
- Enhances accuracy in detecting audio signatures.
- Reduces computational load on processors.
- Improves efficiency in audio analysis tasks.
- Benefits:**
- Enhanced audio detection capabilities.
- Increased processing efficiency.
- Improved accuracy in identifying audio sources.
- Commercial Applications:**
Potential commercial applications include security systems, media content recognition software, and environmental monitoring devices. The technology could be valuable in industries such as law enforcement, entertainment, and environmental protection.
- Questions about Audio Signature Detection:**
1. How does the apparatus determine time differences of arrival for audio sensors?
- The apparatus analyzes audio recordings from multiple sensors to calculate time differences of arrival.
2. What are the benefits of matching time differences with virtual source time differences?
- Matching time differences with virtual source time differences helps in accurately identifying the location of audio sources.
Original Abstract Submitted
methods, apparatus, systems and articles of manufacture are disclosed to improve detection of audio signatures. an example apparatus includes at least one memory, instructions in the apparatus, and processor circuitry to execute the instructions to: determine a first time difference of arrival for a first audio sensor of a meter and a second audio sensor of the meter based on a first audio recording from the first audio sensor and a second audio recording from the second audio sensor; determine a second time difference of arrival for the first audio sensor and a third audio sensor of the meter based on the first audio recording and a third audio recording from the third audio sensor; determine a match by comparing the first time difference of arrival to i) a first virtual source time difference of arrival and ii) a second virtual source time difference of arrival; in response to determining that the first time difference of arrival matches the first virtual source time difference of arrival, identify a first virtual source location as the location of a media presentation device presenting media; and remove the second audio recording to reduce a computational burden on the processor.
