摘要： A method and an information processing apparatus to generate a digital score file of a song are described. The information processing apparatus includes processing circuitry. The processing circuitry is configured to obtain a candidate audio file satisfying a first condition from audio files of unaccompanied singing of the song without instrumental accompaniment. The processing circuitry is configured to divide the candidate audio file into valid audio segments based on timing information of the song, and extract pieces of music note information from the valid audio segments. Each of the pieces of music note information includes at least one data set of a music note in the song. The data set includes an onset time, a duration, and a music note value of the music note. The processing circuitry is configured to generate the digital score file based on the pieces of music note information.

摘要： Methods and apparatus to classify media based on a pitch-independent timbre attribute from a media signal are disclosed. An example apparatus includes means for accessing a media signal; and means for: determining a spectrum of audio corresponding to the media signal; and determining a timbre-independent pitch attribute of audio of the media signal based on an inverse transform of a complex argument of a transform of the spectrum.

摘要： Methods and apparatus to classify media based on a pitch-independent timbre attribute from a media signal are disclosed. An example apparatus includes an interface to receive a media signal; a timbre database to store reference pitch-less timbre spectrums; and a processor to: compare a pitch-less timbre spectrum of the media signal to the reference pitch-less timbre spectrums; and classify the media signal based on data corresponding to a reference pitch-less timbre spectrum of the reference pitch-less timbre spectrums that matches the pitch-less timbre spectrum, the classification corresponding to at least one of an instrument or a genre.

摘要： Apparatus, methods, and other embodiments associated with producing gradient waveforms derived from music are provided. A piece of encoded music (e.g., MP3 file) is converted to an encoding gradient associated with a magnetic resonance fingerprinting (MRF) pulse sequence. The encoding gradient may be optimized with respect to maximum gradient amplitude, gradient slew rate, and other properties of a magnetic resonance (MR) apparatus that will perform the MRF pulse sequence. The MR apparatus may then be controlled to perform an MRF procedure using the encoding gradient. Performing the MRF procedure using the encoding gradient may cause the MR apparatus to reproduce the piece of encoded music. The encoding gradient may be manipulated (e.g., rotated) to encode additional lines in k-space.

摘要： A detection system is provided for detecting a musical note played on a string instrument having a fretboard provided with a plurality of conductive frets and conductive strings. The system includes at least one conductor coupled to each of the frets; an inverter having a first terminal coupled to the conductor and a second terminal coupled to the conductive string, the inverter being configured to logically invert a signal transmitted therethrough, such that when the conductive string is pressed against one of the frets allowing thereby for a signal to be transmitted therethrough, the signal is sequentially inverted between two logical states at a frequency being dependent on the distance between the inverter and the fret; a frequency detector configured to measure the frequency; and a controller configured for determining the location of the fret along the fretboard in accordance with the frequency, and to thereby detect the musical note.

摘要： The present invention relates to the field of audio recognition, in particular to computer implemented note recognition methods in a gaming application. Furthermore, the present invention relates to improving latency of such audio recognition methods. One of the embodiments of the invention described herein is a method for note recognition of an audio source. The method includes: dividing an audio input into a plurality of frames, each frame having a pre-determined length, conducting a frequency analysis of at least a set of the plurality of frames, based on the frequency analysis, determining if a frame is a transient frame with a frequency change between the beginning and end of the frame, comparing the frequency analysis of each said transient frame to the frequency analysis of an immediately preceding frame and, based on said comparison, determining at least one probable pitch present at the end of each transient frame, and for each transient frame, outputting pitch data indicative of the probable pitch present at the end of the transient frame.
