摘要： Methods, systems and computer readable media for altering an audio output are provided. In some embodiments, the system may change the original frequency content of an audio data file to a second frequency content so that a recorded audio track will sound as if a different person had recorded it when it is played back. In other embodiments, the system may receive an audio data file and a voice signature, and it may apply the voice signature to the audio data file to alter the audio output of the audio data file. In that instance, the audio data file may be a textual representation of a recorded audio data file.

摘要： Digital audio sample data are adaptively processed for interpolation based on whether the frequency at which the digital audio signal samples reverse polarity is at least equal to a predetermined threshold, the threshold being determined by their sampling frequency. If so, the digital audio signal samples are subjected to zero-order interpolation, with zero-inserting between the samples followed by lowpass filtering; if not, the samples are subjected to Lagrange (spline) interpolation processing.

摘要： A playback apparatus is able to present song categories to the user that are suited to the current environmental noise. An audio pickup picks up noise data of the surrounding environment. A noise analyzer analyzes the noise data, and then extracts characteristic quantities expressing the characteristics of the noise data. A noise categorizer categorizes the noise data on the basis of the extracted noise data characteristic quantities. A content category database stores content data recorded onto a recording medium in association with categories based on characteristic quantities of the content data. A content category selector cross-references the noise data categorization result with the content category database, and on the basis thereof, selects a plurality of content data categories from among the categorized content data recorded onto the recording medium. A display unit then displays the selected plurality of content data categories.

摘要： A signal processing device includes: a frequency conversion processing unit that sets, as a processing target signal, a section in which a peak signal level exceeds a first threshold in an input sound signal and applies frequency conversion processing to the processing target signal to acquire power levels in respective plural bands; and an amplitude compressing unit that executes, when a power level exceeding a second threshold is present among the power levels in the respective plural bands acquired by the frequency conversion processing unit, amplitude compression processing for compressing a signal level of the processing target signal at a compression ratio at which the peak signal level of the processing target signal falls within the first threshold and, otherwise, prohibits the execution of the amplitude compression processing.

摘要： A user-friendly system for real time performance and user modification of one or more previously recorded musical compositions facilitates user involvement in the creative process of a new composition that reflects the user's personal style and musical tastes. Such a system may be implemented in a small portable electronic device such as a handheld smartphone that includes a stored library of musical material including original and alternative versions of each of several different components of a common original musical composition, and a graphic user interface that allows the user to select at different times while that original composition is being performed, which versions of which components are to be incorporated to thereby create in real time a new performance that includes elements of the original performance, preferably enhanced at various times with user selected digital sound effects including stuttering and filtering. The system may also optionally comprise a visualizer module that renders a visual animation that is responsive to at least the rhythm and amplitude of the system's audio output, not only for entertainment value but also to provide visual feedback for the user.
