Reverberation techniques for 3D audio are disclosed. In an example method, a three-dimensional (3D) reverberation is applied to a sound object placed at a sound object position in a sound room. The sound object originates from a sound object position. A sound object signal is received. A 3D spatial room response (SRR) signal is computed corresponding to the user-selected position. A time convolution operation is performed between an audio signal of the sound object signal and the computed SRR value to generate a reverberated signal.

A method of processing textual and graphical feedback of a virtual audience of a performance for compensating and providing sonic cues to the performers through monetizing and audially representing, respectively, the textual and graphical feedback.

A sound signal generation device according to one embodiment includes a memory storing instructions, and a processor that implements the instructions and execute a plurality of tasks, including a signal generation task that generates a sound signal based on first operation data corresponding to an operation to a key, and an attenuation control task that controls an attenuation velocity of the sound signal to one of a first velocity or a second velocity that is faster than the first velocity, based on the first operation data, and second operation data corresponding to an operation to a pedal, wherein the attenuation control task varies a value of the second velocity based on an operation velocity of the key included in the first operation data to control the attenuation velocity of the sound signal to the second velocity.

Systems and methods directed to combining audio tracks are provided. More specifically, a first audio track and a second audio track are received. The first audio track is separated into a vocal component and one or more accompaniment components. The second audio track is separated into a vocal component and one or more accompaniment components. A structure of the first audio track and a structure of the second audio track are determined. The first audio track and the second audio track are aligned based on the determined structures of the tracks. The vocal component of the first audio track is stretched to match a tempo of the second audio track. The stretched vocal component of the first audio track is added to the one or more accompaniment components of the second audio track.
