摘要： A method for providing multi-region instrument support in an audio player is described. A set of user defined instruments and a set of MIDI data is received. At least one multi-region instrument in the set of user defined instruments is identified. Each region in the multi-region instruments is mapped to a single region instrument with the same parameters as the region. A new instrument number is assigned to each single region instrument. The MIDI data is modified based on the mapping and assigning.

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.
摘要翻译： 通常，本公开的技术可以用于控制分配给音频处理模块的带宽的利用。 例如，为了处理各种音频合成参数，音频处理模块可以检索参考波形样本，以用于生成诸如MIDI帧之类的音频帧内的语音的音频信息。 在某些情况下，可用于从存储器检索参考波形的带宽量受到限制。 为了管理所分配的带宽的利用率，带宽控制模块估计为音频帧的所有语音检索参考波形所需的带宽量，并且当带宽估计超过该频带估计值时，从所生成的音频信息中选择要消除的一个或多个语音 分配带宽。

摘要： This disclosure describes techniques for processing audio files that comply with the musical instrument digital interface (MIDI) format. In particular, this disclosure describes storage of MIDI parameters for efficient access by a processor and a hardware unit. The processor may be a digital signal processor (DSP) and the hardware unit may be specifically designed to process MIDI parameters. In one aspect, this disclosure provides an apparatus comprising a processor that converts a MIDI event into MIDI parameters, a hardware unit that uses MIDI parameters to generate audio samples, and a plurality of storage units that store MIDI parameters which are accessible by both the processor and the hardware unit.

摘要： A method for providing variable root note support in an audio player is described. A file with Musical Instrument Digital Interface (MIDI) data and a set of user defined instruments is received. A metric is determined using a user defined root note in the user defined instruments, a key number for a MIDI note in the MIDI data, and a player specific root note. The key number is adjusted based on the metric.
