Abstract: Systems and methods for composing a virtual environment are provided. The virtual environment may represent a room or other space having specified parameters. The system may facilitate placement of 3D models of objects in the virtual environment, where the 3D models correspond to one or more objects depicted in a 2D image, and the placement of the 3D models is algorithmically determined based on placement rules to generate an arrangement of the 3D models based on a layout of the one or more objects in the 2D image. The system can execute the placement rules to algorithmically determine placement locations of the 3D models corresponding to objects depicted in the 2D image.

Abstract: The application relates to a computer implemented method and system for modifying at least one feature of an input audio signal based on features in a guide audio signal. The method comprises: determining matchable and unmatchable sections of the guide and input audio signals; generating a time-alignment path for modifying the at least one feature of the input audio signal in the matchable sections of the input audio signal based on corresponding features in the matchable sections of the guide audio signal, based on the time-alignment path, modifying the at least one feature in the matchable sections of the audio input signal.

Abstract: A digitised audio signal, such as an amateur's singing, and a digital guide audio signal are supplied to a time alignment process that produces a time-aligned new signal, time-aligned to the guide signal. Pitch along the time-aligned new signal and along the guide signal is measured in processes and which supply these measurement to a pitch adjustment calculator which calculates a pitch correction factor C's(Fps) from these measurements and the nearest octave ratio of the signals. A pitch changing process modulates the pitch of the time-aligned new signal to produce a time-aligned and pitch adjusted new signal.

A pitch changing process modulates the pitch of the time-aligned new signal to produce a time-aligned and pitch adjusted new signal.
