A method and apparatus for synchronizing audio streamed over a network. The system makes use of a reference track and a common clock that is provided by a server to all participating performers. The performers perform along with and to the reference track wherein the reference track and common clock serve as a baseline reference for all the performers in regard to their audio transmitted to the server. Using the reference track and common clock, the server of the system can reconstruct and synchronize received audio from all the participating performers. The synchronized audio is then provided to a mixer where it is combined and live or real-time adjustments to the audio are made before being provided for broadcast.

A person can use a portable electronic device to electronically purchase or otherwise request a product, service or other deliverable related to audio programming to which the person is listening at the time they initiate the request. The request is fulfilled by a service that analyzes the audio content to identify the deliverable the person desires.

A system includes an audio broadcast device, headphones and an interface device. The audio broadcast device may be configured to generate a plurality of audio tracks. The headphones may be configured to perform noise cancellation of ambient audio, decode one of the plurality of audio tracks selected by a user and playback a personalized audio track in response to the selected audio track and user settings. The interface device may be configured to receive the user settings and enable the user to select one of the audio tracks. The headphones may receive the selected audio track from the audio broadcast device in response to the selection using the interface. The user settings may be applied to the selected audio track to generate the personalized audio track.

A broadcast transmitting apparatus and method, and a broadcast playback apparatus and method for providing an object-based audio by encoding and decoding a multichannel audio signal are provided. The broadcast transmitting apparatus may generate audio identification information used to determine whether the multichannel audio signal is an object-based audio signal. When the multichannel audio signal is determined to be the object-based audio signal, based on the audio identification information, the broadcast playback apparatus may control and output the multichannel audio signal for each channel.

The present disclosure relates to methods and apparatus for audio coding. A method of encoding a portion of an audio signal comprises determining whether the portion of the audio signal is likely to contain dense transient events, and if it is determined that the portion of the audio signal is likely to contain dense transient events, quantizing the portion of the audio signal using a quantization 5 mode that applies a substantially constant signal-to-noise ratio over frequency for the portion of the audio signal. The present disclosure further relates to a method of detecting dense transient events in a portion of an audio signal.

A method, a device, and a system for broadcasting audio are described. The method is applied to a master device, and the method comprises: receiving, by the master device, a first audio data packet broadcast by a target slave device based on a reverse link in one or more reverse link time slots, one or more of the sub-event time slots being configured as the one or more reverse link time slots when the reverse link is enabled; and broadcasting, by the master device, a second audio data packet based on a forward link in one or more forward link time slots, one or more of the sub-event time slots used as one or more forward link time slots when the forward link is enabled, wherein at least one of the sub-event time slots is used as the reverse link time slot and the forward link time slot respectively in two isochronous intervals. In this way, a bi-directional communication between the master device and a slave device can be realized.
