Abstract: The present invention relates to systems and/or methods that generate playlist(s) for a library or collection of media items via selecting a plurality of seed items, at least one of which is an undesirable seed item. Some of the seed items are desirable indicating that a user prefers additional media items similar to the desirable seed items and others are undesirable indicating that the user prefers additional media items dissimilar to the undesirable seed items. Additionally, the seed items can be weighted to establish a relative importance of the seed items. The invention compares media items in the collection with the seed items and determines which media items are added into the playlist by computation of similarity metrics or values. The playlist can be regenerated by adding desirable seed items to the playlist and removing media items from the playlist (e.g., undesirable seed items).

Abstract: A frequency spectrum is detected by analyzing a frequency of a voice waveform corresponding to a voice synthesis unit formed of a phoneme or a phonemic chain. Local peaks are detected on the frequency spectrum, and spectrum distribution regions including the local peaks are designated. For each spectrum distribution region, amplitude spectrum data representing an amplitude spectrum distribution depending on a frequency axis and phase spectrum data representing a phase spectrum distribution depending on the frequency axis are generated. The amplitude spectrum data is adjusted to move the amplitude spectrum distribution represented by the amplitude spectrum data along the frequency axis based on an input note pitch, and the phase spectrum data is adjusted corresponding to the adjustment. Spectrum intensities are adjusted to be along with a spectrum envelope corresponding to a desired tone color. The adjusted amplitude and phase spectrum data are converted into a synthesized voice signal.

Abstract: A method for determining rhythm units (beats per minute or BPM) in (digital) audio data forming a musical piece. The audio data is split among a plurality of determination paths wherein it is subdivided into predetermined frequency bands. The data is analyzed for transients in order to determine attack events. In addition, the time intervals between two successive attack events are measured. In this case, the time intervals are averaged and defined as the frequency-band-specific rhythm unit (BPM) of the audio data in the respective determination path. Thus, the rhythm unit which exhibits the highest beat number (BPM number) is selected from the frequency-band-specific rhythm units (BPM) of the determination paths.

Abstract: Beating sounds and attenuation sounds generated by first original sound generators (100) corresponding to elements of a conventional drum set are received by augmented microphones. A sound modulator (26) is used for modulating tones of the electronic sounds from the augmented microphones without any digital conversion. A reproducer (34) is used for reproducing the output sounds from the sound modulator (26). Because the processes of digitally converting, transferring signals by optical couplers, and selecting recorded sounds for reproducing are eliminated, the reproduced sounds can represent subtle techniques of the performer by directly using the original sounds generated when the first original sound generators (100) are beaten.
