Audio buffers with audio effects
First Claim
1. A method for communicating between components of an audio generation system, comprising:
- requesting the creation of an audio buffer having one or more audio effect resources including a first audio effect resource configured to receive audio data from an audio data source and modify the audio data to generate modified audio data, the one or more audio effect resources further including at least a second audio effect resource configured to receive the modified audio data from the first audio effect resource and further modify the modified audio data to generate a modified audio data output of the audio buffer;
routing the modified audio data to the second audio effect resource and to at least an additional audio buffer;
issuing a call to create the audio buffer, the call including parameters that specify an address of an audio buffer description data structure and an address of a variable of an application program that receives an interface of the audio buffer; and
receiving a pointer to the interface of the audio buffer.

Abstract
An audio buffer includes one or more audio effect resources that modify audio data received from an audio data source. A first audio effect resource in the audio buffer receives audio data from the audio data source and modifies the audio data to generate a stream of audio data. Subsequent audio effect resource(s) in the audio buffer receives the stream of audio data from the first audio effect and further modifies the audio data to generate a stream of modified audio data. The stream of modified audio data can then routed from the audio buffer to a second audio buffer, or communicated to an audio rendering component that produces an audio rendition corresponding to the modified audio data.

5. A method for communicating between components of an audio generation system, comprising:
-
requesting the creation of an audio buffer having one or more audio effect resources including a first audio effect resource configured to receive audio data from an audio data source and modify the audio data to generate modified audio data, the one or more audio effect resources further including at least a second audio effect resource configured to receive the modified audio data from the first audio effect resource and further modify the modified audio data to generate a modified audio data output of the audio buffer; routing the modified audio data to the second audio effect resource and to at least an additional audio buffer; issuing a call to create the audio buffer with the one or more audio effects, the call including parameters that specify; an address of an array of audio effect description data structures that describe one or more audio effect configurations; an address of an array of elements that each receive a value that indicates the result of an attempt to create a corresponding audio effect; and a value that indicates the number of audio effect description data structures and the number of elements; and the method further comprising, receiving a value that indicates the status of a corresponding audio effect. - View Dependent Claims (6, 7, 8, 9, 10, 11)

12. A method for communicating between components of an audio generation system, comprising:
-
requesting the allocation of resources for an audio buffer having one or more audio effect resources including a first audio effect resource configured to receive audio data from an audio data source and modify the audio data to generate modified audio data, the one or more audio effect resources further including at least a second audio effect resource configured to receive the modified audio data from the first audio effect resource and further modify the modified audio data to generate a modified audio data output of the audio buffer; routing the modified audio data to the second audio effect resource and to at least an additional audio buffer; issuing a call to allocate the resources of the audio buffer, the call including parameters that specify;
a type of resources to be allocated;an address of an array of variables that each receive a status indicator to indicate the status of an audio effect associated with the audio buffer; a value to indicate the number of variables in the array of variables; and the method further comprising, receiving a value that indicates the status of an audio effect associated with the audio buffer. - View Dependent Claims (13, 14, 15, 16, 17)
