In some embodiments, virtualization methods for generating a binaural signal in response to channels of a multi-channel audio signal, which apply a binaural room impulse response (BRIR) to each channel including by using at least one feedback delay network (FDN) to apply a common late reverberation to a downmix of the channels. In some embodiments, input signal channels are processed in a first processing path to apply to each channel a direct response and early reflection portion of a single-channel BRIR for the channel, and the downmix of the channels is processed in a second processing path including at least one FDN which applies the common late reverberation. Typically, the common late reverberation emulates collective macro attributes of late reverberation portions of at least some of the single-channel BRIRs. Other aspects are headphone virtualizers configured to perform any embodiment of the method.

The present disclosure provides a method and system for voice enhancement. The method and system of the present disclosure may simultaneously perform signal processing of two paths on an input signal. The first path signal processing includes receiving an audio source input and performing dynamic loudness balancing on the audio source input based on a first gain control parameter. The second path signal processing includes: performing voice detection on the audio source input and calculating a detection confidence; and calculating a second gain control parameter based on the detection confidence. The first path signal processing and the second path signal processing may be synchronous or asynchronous. The method of the present disclosure also includes updating the first gain control parameter with the second gain control parameter calculated by a second processing path and performing the first path signal processing based on the updated first gain control parameter.

An audio processing device includes: a sound level measuring circuit arranged to operably generate multiple sound level values, wherein the multiple sound level values respectively correspond to the sound levels generated by an audio playback device at multiple time points or the sound levels received by a microphone at multiple time points; an audio dose calculating circuit coupled with the sound level measuring circuit and arranged to operably generate an audio dose value corresponding to a measuring period based on the multiple sound level values and contents of a weighting table; a control circuit coupled with the audio dose calculating circuit and arranged to operably compare the audio dose value with a dose threshold to determine whether to generate a control signal or not; and an indication signal generating circuit coupled with the control circuit and arranged to operably generate a corresponding indication signal according to the control signal.

A signal generating apparatus includes: a memory configured to store instructions; and a processor communicatively connected to the memory and configured to execute the stored instructions to function as: a first generator configured to generate a processed signal by adjusting frequency characteristics of an audio signal representative of a sound from a virtual sound source based on a Head-Related Transfer Function (HRTF) corresponding to a target position of the virtual sound source; and a second generator configured to: generate, based on the processed signal generated by the first generator, a plurality of output signals in one-to-one correspondence with a plurality of loudspeakers; and perform panning processing to adjust a level of each output signal of the plurality of output signals based on the target position.

Voice command type entry used as a basis for applying “audio effects” (see definition herein), “sound effects” (see definition herein) and/or audio edits (see definition herein) to a sound signal. This may be done so that the various types of instructed audio processing evoke, in typical listeners, a desired sentiment or mood. Artificial intelligence may be used to accomplish this objective.

An audio system with a loudspeaker configured to create an audio output, a sensor configured to detect at least the presence of at least one person at a position relative to the loudspeaker, and a processor configured to cause the loudspeaker to alter the audio output based on the position of the at least one person relative to the loudspeaker. Altering of the audio output includes adjusting at least one of a volume, a time delay, an equalization, or a radiation pattern of the audio output.

A method and corresponding system for correcting for deviations in a performance that includes a plurality of audio sources, the method comprising detecting a parameter relating to an audio source, determining if the parameter deviates from a predetermined characteristic and in response to it being determined that the parameter deviates from the predetermined characteristic, causing display of a user interface configured to control the parameter, to allow a user to correct the deviation.
