Abstract
The present technology relates to a signal processing apparatus and method, and a program that make it possible to reduce an arithmetic operation amount. The signal processing apparatus performs, on the basis of audio object mute information indicative of whether or not a signal of an audio object is a mute signal, at least either one of a decoding process or a rendering process of an object signal of the audio object. The present technology can be applied to a signal processing apparatus.
Claims13
A signal processing apparatus comprising:
- processing circuitry configured to:
- perform, on a basis of audio object mute information indicative of whether or not a signal of an audio object is a mute signal, at least either one of a decoding process or a rendering process of an object signal of the audio object;
- and
- perform an HRTF (Head Related Transfer Function) process on a basis of a virtual speaker signal obtained by the rendering process and used to reproduce sound by a virtual speaker and virtual speaker mute information indicative of whether or not the virtual speaker signal is a mute signal.
A signal processing method, executed by processing circuitry, the method comprising:
- performing on a basis of audio object mute information indicative of whether or not a signal of an audio object is a mute signal, at least either one of a decoding process or a rendering process of an object signal of the audio object;
- and
- performing an HRTF (Head Related Transfer Function) process on a basis of a virtual speaker signal obtained by the rendering process and used to reproduce sound by a virtual speaker and virtual speaker mute information indicative of whether or not the virtual speaker signal is a mute signal.
A non-transitory computer readable medium storing instructions that, when executed by processing circuitry, perform a signal processing method comprising:
- performing, on a basis of audio object mute information indicative of whether or not a signal of an audio object is a mute signal, at least either one of a decoding process or a rendering process of an object signal of the audio object;
- and
- performing an HRTF (Head Related Transfer Function) process on a basis of a virtual speaker signal obtained by the rendering process and used to reproduce sound by a virtual speaker and virtual speaker mute information indicative of whether or not the virtual speaker signal is a mute signal.
