Abstract
A virtual bass enhancing device for enhancing a virtual bass of an input audio signal includes a demixer, configured to extract at least one audio channel from the input audio signal, wherein the audio channel corresponds to an acoustic source, or to a group of acoustic sources, of the input audio signal, at least one virtual bass enhancing unit configured to generate overtones for enhancing a bass perception of the audio channel, and at least one adder configured to add the overtones to the input audio signal so as to generate an enhanced audio signal.

A virtual bass enhancing device for enhancing a virtual bass of an input audio signal, the virtual bass enhancing device comprising:
- a demixer, configured to extract at least one audio channel from the input audio signal, wherein the at least one audio channel corresponds to an acoustic source, or to a group of acoustic sources, of the input audio signal,
- at least one virtual bass enhancing unit configured to generate overtones for enhancing a bass perception of the at least one audio channel,
- at least one adder configured to add the overtones to the input audio signal so as to generate an enhanced audio signal.
A virtual bass enhancing device for enhancing a virtual bass of an input audio signal, the virtual bass enhancing device comprising a processor and a memory,
- the memory comprising instructions to cause the processor to implement a demixer, configured to extract at least one audio channel from the input audio signal, wherein the at least one audio channel corresponds to an acoustic source, or to a group of acoustic sources, of the input audio signal,
- the memory further comprising instructions to cause the processor to implement at least one virtual bass enhancing unit configured to generate overtones for enhancing a bass perception of the at least one audio channel,
- the memory further comprising instructions to cause the processor to implement at least one adder configured to add the overtones to the input audio signal so as to generate an enhanced audio signal.
