Intensifying contextually relevant sound events for time-delayed broadcast uses multiple directional microphones that capture sound events from a specific location within regions of a stadium. The events are contextually relevant to the environment, such as a referee's whistle sound. A processor executes signal processing of the captured events on each channel to produce audio samples each having a signal profile. The profiles are automatically compared to reference feature templates stored in a database, correspond to pre-identified sound events of contextual relevance. The signal processing accentuates characteristic traits in the events, reflective of contextually relevant events that should be included in a final composite audio output for transmission. If the comparison of samples to the feature templates suggests a high probability of a correspondence, then buffered audio for that channel is introduced into a final audio mix.

Example methods and apparatus to audio watermarking and watermark detection and extraction are disclosed herein. An example apparatus disclosed herein includes memory, computer readable instructions, and processor circuitry to execute the computer readable instructions to at least detect a first symbol, a second symbol, a third symbol, and a fourth symbol sequentially in encoded audio samples, determine whether the first symbol is a synchronization symbol, in response to a determination that the first symbol is a synchronization symbol, determine that the first symbol and the third symbol are associated with a first message and the second symbol and the fourth symbol are associated with a second message, and output at least one of the first message or the second message.

A system for auditing performance data in commercial venues having one or more computing devices located in venues where live or pre-recorded music is performed. The computing devices capture and store content in each venue using at least one audio input configured for professional audio performances. The computing devices store the content as a content data record with associated identifiers for date, time, and venue location. The content data records are transferred from each venue to a central server. Encryption keys encrypt the content data records from each venue to verify the authenticity of the content transmitted from the venues to the server. The server includes a processor for opening, reviewing, and separating the content data records from each venue into distinct files, each file comprising an individual work performed in the venue. The system further includes an interface for providing access to the archived content data records at the server.

Methods, apparatus, systems and articles of manufacture are disclosed. An example apparatus includes a controller to cause a people meter to emit a prompt for input of audience identification information at a first time and determine a first audience count based on the input, an audio detector to determine a second audience count based on signatures generated from audio data captured in the media environment, and a comparator to cause the people meter to not emit the prompt for at least a first time period after the first time when the first audience count is equal to the second audience count.

Methods and apparatus to audio watermarking and watermark detection and extracted are described herein. An example method includes receiving a media content signal, sampling the media content signal to generate samples, storing the samples in a buffer, determining a first sequence of samples in the buffer, determining a second sequence of samples in the buffer, wherein the second sequence of samples is of substantially equal length as the first sequence of samples, calculating an average of the first sequence of samples and the second sequence of samples to generate an average sequence of samples, extracting an identifier from the average sequence of samples, and storing the identifier in a tangible memory.
