In general, techniques are described by which to embed enhanced audio transports in backward compatible bitstreams. A device comprising a memory and one or more processors may be configured to perform the techniques. The memory may store the backward compatible bitstream, which conforms to a legacy transport format. The processor(s) may obtain, from the backward compatible bitstream, legacy audio data that conforms to a legacy audio format, and obtain, from the backward compatible bitstream, extended audio data that enhances the legacy audio data. The processor(s) may also obtain, based on the legacy audio data and the extended audio data, enhanced audio data that conforms to an enhanced audio format, and output the enhanced audio data to one or more speakers.

Embedding enhanced audio transports in backward compatible audio bitstreams

In general, techniques are described for audio editing of higher-order ambisonic audio data. A device comprising a memory and one or more processors may be configured to perform the techniques. The memory may be configured to store a higher order ambisonic (HOA) representation of the audio object. The one or more processors may be configured to add a source tail to the HOA representation of the audio object by storing one or more spherical harmonic (SH) basis functions associated with the audio object to a buffer.

Editing of higher-order ambisonic audio data

In general, techniques are described for editing of higher-order ambisonic audio data. A device comprising a memory and one or more processors may be configured to perform the techniques. The memory may be configured to store spherical harmonic (SH) basis functions. The one or more processors may be configured to manipulate the SH basis functions associated with higher order ambisonics coefficients to alter a direction of an audio object represented by the higher order ambisonics coefficients.

According to a disclosed embodiment, an incoming call from a first telephone number is received (). A variable indicating the number of calls received from the first telephone number is incremented (). The variable is compared to a threshold variable (). Subsequently, the user is prompted to save the first telephone number in an address book () when the variable indicating the number of times an incoming call is received from the first telephone number is equal to, or greater than, the threshold variable. The first telephone number is then stored in the address book. Moreover, an apparatus can be assembled () to provide cellular telephone users with, for example, instructions and information via a speaker () and an LCD display (). The apparatus is configured to provide instructions and information to the cellular telephone user at appropriate times, thereby increasing the cellular telephone's usefulness.
