20080229913 | BANDWIDTH CONTROL FOR RETRIEVAL OF REFERENCE WAVEFORMS IN AN AUDIO DEVICE - 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.

20120325074 | MUSIC MACHINE - This application describes a method and an apparatus which enable one to compose music using hierarchical musical scales and harmonic sequences, where each harmonic sequence of a higher level is derived from the one on the lower level. Frequencies associated with harmonic sequence on each level above the first one are obtained as multiples of the corresponding frequencies on a lower level. The sets of multipliers used to scale the frequencies between the levels is restricted to respective groups of rational numbers, or scales, where each level in a harmonic hierarchy can be related to its own scale, or a single scale can be used for all levels. When composing for an orchestra of multiple instruments, harmonic sequences and scales can be assigned independently to each musical instrument. | 12-27-2012 |

20130061735 | POLYPHONIC NOTE DETECTION - Processor-implemented methods and systems for polyphonic note detection are disclosed. The method includes converting a portion of a polyphonic audio signal from a time domain to a frequency domain. The method includes detecting a fundamental frequency peak in the frequency domain. The method then detects a defined number of integer-interval harmonic partials. If a defined number of integer-interval harmonic partials relative to the fundamental frequency peak are detected the fundamental frequency is recorded as a detected note. This process is repeated for each fundamental frequency until each note in the polyphonic audio signal has been detected. For example, this method allows detection of each note in a strummed guitar chord to provide feedback on the tuning of each string in a strummed chord or allows detection and feedback of the timing and pitch errors for guitar chords played along with a reference track. | 03-14-2013 |
