摘要： A method and system for automatically generating the lyrics of a song is provided to reduce the time and cost of song transcription. The method may include isolating vocal content from instrumental content for a provided audio input. The vocal content may be processed or normalized to obtain a natural vocal content. A speech recognizer may then be utilized to transcribe a plurality of words of the natural vocal content. The plurality of words may then be organized and saved as a lyric time code. The lyric time code may be stored with an audio file or used to generate dynamic outputs associated with the vocal content. The system may include hardware and software to provide deep neural networks used by artificial intelligence to carry out steps of the method.

摘要： The invention provides a method for generating a sound effect audio clip based on a mix of audible characteristics of two existing audio clips. The method comprises selecting first and second audio clips, mapping evolution of time of a plurality of predetermined audible characteristics of the first audio clip to arrive at first mapping data accordingly. The second audio clip is then modified based on the first mapping data, so as to at least partially apply evolution of time of audible characteristics from the first audio clip to the second audio clip, and outputting the sound effect audio clip in response to the modified second audio clip. Preferred audible characteristics are such as: amplitude, pitch, and spectral envelope (e.g. formant), which are each represented in mapping data as values representing the audible characteristics for the duration of the first audio clip at a given time resolution, where each value represents a value or a set of values representing the result of an analysis over a predetermined time windows. Especially, the second audio clip may also be mapped with respect to evolution of time of corresponding audible characteristics, and the modification of the second audio clip can then be performed in response to a mix of the two mapping data sets, e.g. by a frame-by-frame processing. A time alignment of the first and second audio clips may be performed, so that the two audio clips have the same duration prior to being processed.

摘要： This is a method and installation in which a time-domain digital audio signal is split into a plurality of narrow-band time-domain digital audio signals confined to specific frequency bands, short-term segments of which are temporarily stored in memory. The method comprises the use of signal processing algorithms for extracting multiple signal features from said short-term segments in a fixed sequence or upon request from a decision-making algorithm. Said decision-making algorithm makes tentative or final decisions about the type of occupancy of frequency bands resulting from the extracted features. Said decision- making algorithm may request from said signal processing algorithms further specific feature extractions from specific short-term segments and make further tentative or final decisions about the type of occupancy of frequency bands resulting from the requested features. Next, said decision-making algorithm stores its tentative decisions and makes final decisions about band occupancy for processing together with results from later short-term segments. Eventually, said decision-making algorithm outputs final decisions derived from current and past short-segments in the form of a set of notes having been played over some recent time interval, together with information as to the timing of each note from the set.

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： A match score provides a semantically-meaningful quantification of the aural similarity of two chromae from two corresponding audio sequences. The match score can be applied to the chroma pairs of two corresponding audio sequences, and is independent of the lengths of the sequences, thereby permitting comparisons of matches across subsequences of different length. Accordingly, a single cutoff match score to identify "good" audio subsequence matches can be determined and has both good precision and good recall metrics. A function for determining the match score is determined by establishing a function P M indicating probabilities that chroma correspondence scores indicate semantic correspondences, and a function P R indicating probabilities that chroma correspondence scores indicate random correspondences, repeatedly updating P M and the match function based on existing values of P M and the match function as applied to audio subsequences with known semantic correspondences.

摘要： Improvisation or playing along with a musical group or with a song is enjoyable to people and musicians of all ability levels. However, it is easy to play notes which do not harmonize with other notes and pitches which are being played. Provided herein is a method, computer program product and electronic device for assigning a set of pitches to a plurality of cells of an electronic device having a touch screen input device. The method may include the steps of obtaining an input chord, disassembling the chord into at least one base note and a plurality of individual voices, arranging a predetermined number of voices of the chord according to at least one predefined rule, and assigning at least one set of pitches to a plurality of cells of an electronic device, said set of pitches corresponding to the base note and arranged predetermined number of voices of the chord. The present method allows a musician to freely play along without the possibility of playing an errant note as the user does not control the actual pitch associated with the cells being indicated by a user on the touch screen.
