    摘要: An electronic music system which imitates acoustic instruments addresses the problem wherein the audio spectrum of a a recorded note is entirely shifted in pitch by transposition. The consequence of this is that unnatural formant shifts occur, resulting in the phenomenon known in the industry as "munchkinization." The present invention eliminates munchkinization, thus allowing a substantially wider transposition range for a single recording. Also, the present invention allows even shorter recordings to be used for still further memory improvements. An analysis stage separates and stores the formant and excitation components of sounds from an instrument. On playback, either the formant component or the excitation component may be manipulated.

    摘要: A system and method that quantifies a sound into dynamic pitch-based graphs that correlate to the pitch frequencies of the sound. The system records a sound, such as musical notes. A pitch detection algorithm identifies and quantifies the pitch frequencies of the notes. The algorithm analyzes the pitch frequencies, and graphically displays the pitch frequency and notes in real time as fluctuating circles, rectangular bars, and lines that represent variances in pitch. The algorithm comprises a modified Type 2 Normalized Square Difference Function that transforms the musical notes into the pitch frequencies. The Type 2 Normalized Square Difference Function analyzes the peaks of the pitch frequency to arrive at a precise pitch frequency, such as 440 Hertz. A Lagrangian interpolation enables comparative analysis and teaching of the pitches and notes. The algorithm also performs transformations and heuristic comparisons to generate the real time graphical representation of the pitch frequency.

    摘要: System, apparatus and method for determining semantic information from audio, where incoming audio is sampled and processed to extract audio features, including temporal, spectral, harmonic and rhythmic features. The extracted audio features are compared to stored audio templates that include ranges and/or values for certain features and are tagged for specific ranges and/or values. The semantic information may be associated with audio signature dataExtracted audio features that are most similar to one or more templates from the comparison are identified according to the tagged information. The tags are used to determine the semantic audio data that includes genre, instrumentation, style, acoustical dynamics, and emotive descriptor for the audio signal.

    摘要: A method and an electronic data processing apparatus for wave synthesis that retains the true qualities of naturally occurring sounds, such as those of musical instruments, speech, or other sounds. Transfer functions representative of recorded sound samples are pre-calculated and stored for use in an interpolative process to generate a transfer function representative of the sound to be synthesized. The preferred transfer functions are Chebyshev polynomial-based transfer functions, which assure a highly predictable harmonic content of synthesized sound. Output sound generation is driven by time domain signals produced by reconversion of a sequence of interpolated transfer functions. Non-harmonic sounds are synthesized using multiple frequency inputs to the reconverting (waveshaping) stage, or by parallel waveshaping stages. Speech sibilants and noise envelopes of instruments are synthesized by the input of noise into the waveshaping stage by modulation of a sinusoid with band-limited noise.
