摘要:
A method and apparatus for creating a signature of a sampled work in real-time is disclosed herein. Unique signatures of an unknown audio work are created by segmenting a file into segments having predetermined segment and hop sizes. The signature then may be compared against reference signatures. One aspect may be characterized in that the hop size of the sampled work signature is less than the hop size of reference signatures. A method for identifying an unknown audio work is also disclosed.

Payment-based audiovisual playback system comprising a microprocessor device associated with a payment device primarily including mass storage means, for storing inter alia the digital compressed visual and sound information to be used. The system is associated through interfaces with digital display means and digital sound playback means which provide a multimedia environment. The invention is characterized in that the digital display means and video monitor are associated with a touch screen associated with an interface programme responsive to outside events, translating them, for the graphic operating system, as mouse events using a library of integrated tools and services, to trigger either a change in the execution of one of the man/machine interface programme modules, or a change in the physical operating parameters of the jukebox.
摘要:
A media data format is described, and devices methods, computer readable medias and a propagating signal in relation to the media data format. The media data format comprises a music data portion defining a music track, and a metadata portion defining metadata associated with said music track. Said metadata comprises a temp metadata type having a tempo class value indicating a tempo class of the music track.

Methods for dynamically creating polyphonic audio files on the handheld mobile wireless communication devices, creating and storing polyphonic files with limited data storage resources on wireless communications handsets by storing reference data in an audio mix data reference file (400), including file name data (410), sound effect data (420), base track data (450), and soundtrack data (450), and integrating audio data reference files and soundtrack data reference files in a polyphonic audio format file for uploading from wireless communications handsets, and combinations thereof.
摘要:
A grand piano (1a) generates acoustic tones through vibrations of strings (1f) and sound board (1g) so that the acoustic tones are converted to analog audio signals at recording points (L/ M/ R) over the sound board (1g), and a group of waveform data sets are produced from the analog audio signal through sampling and analog-to-digital conversion; when electronic tones are generated, delay parameters and volume parameters are determined on the basis of differences between the recording points (L/ M/ R) and tone radiating points (L/ M/ R) occupied by loud speakers (31/ 32/ 33), the sets of waveform data series are sequentially read out from the group of waveform data sets and are modified with the delay parameters and volume parameters so that the electronic tones become close to the acoustic tones.

摘要:
A user records a part of a piece of music performed on the composite audio system (MR) into and reproduces the performance from a floppy disc (FD) in ensemble with another part of the piece of music; while a compact disc player (AR) is producing an audio signal (AL1) from audio data codes, the composite audio system (MR) produces event codes (ED2) representative of local peaks in the audio signal (AL2) for timing control, and stores these event codes (ED2) together with event codes (ED1) representative of note events and duration data codes in the floppy disc (FD); while the composite audio system (MR) and compact disc player (AR) are reproducing the parts of the piece of music, the time intervals among the tones are prolonged and shrunk by using the event codes (ED2) for timing control and actual local peaks so that the tones in one of the parts are produced synchronously with the tones of the other part.
