标题:Bandwidth control for retrieval of reference waveforms in an audio device
发明人：KULKARNI PRAJAKT; DEVALAPALLI SURESH
权利人:QUALCOMM INC
摘要:In general, the techniques of this disclosure may be used to control utilization of bandwidth allocated to an audio processing module. For example, to process various audio synthesis parameters, the audio processing module may retrieve reference waveform samples for use in generating audio information for voices within an audio frame, such as a MIDI frame. In some cases, the amount of bandwidth available for retrieving the reference waveforms from memory is limited. To manage the utilization of the allocated bandwidth a bandwidth control module estimates an amount of bandwidth required to retrieve reference waveforms for all the voices of the audio frame, and selects one or more voices to be eliminated from generated audio information when the bandwidth estimate exceeds the allocated bandwidth.

摘要:This disclosure describes techniques that make use of a plurality of hardware elements that operate simultaneously to service synthesis parameters generated from one or more audio files, such as musical instrument digital interface (MIDI) files. In one example, a method comprises storing audio synthesis parameters generated for one or more audio files of an audio frame, processing a first audio synthesis parameter using a first audio processing element of a hardware unit to generate first audio information, processing a second audio synthesis parameter using a second audio processing element of the hardware unit to generate second audio information, and generating audio samples for the audio frame based at least in part on a combination of the first and second audio information.

摘要:This disclosure describes techniques that make use of a waveform fetch unit that operates to retrieve waveform samples on behalf of each of a plurality of hardware processing elements that operate simultaneously to service various audio synthesis parameters generated from one or more audio files, such as musical instrument digital interface (MIDI) files. In one example, a method comprises receiving a request for a waveform sample from an audio processing element, and servicing the request by calculating a waveform sample number for the requested waveform sample based on a phase increment contained in the request and an audio synthesis parameter control word associated with the requested waveform sample, retrieving the waveform sample from a local cache using the waveform sample number, and sending the retrieved waveform sample to the requesting audio processing element.

摘要:This disclosure describes techniques for processing audio files that comply with the musical instrument digital interface (MIDI) format. In particular, various tasks associated with MIDI file processing are delegated between software operating on a general purpose processor, firmware associated with a digital signal processor (DSP), and dedicated hardware that is specifically designed for MIDI file processing. Alternatively, a multi-threaded DSP may be used instead of a general purpose processor and the DSP. In one aspect, this disclosure provides a method comprising parsing MIDI files and scheduling MIDI events associated with the MIDI files using a first process, processing the MIDI events using a second process to generate MIDI synthesis parameters, and generating audio samples using a hardware unit based on the synthesis parameters.
