In some embodiments, a method for performing enhancement on an audio signal to generate an enhanced audio signal in response to feedback indicative of amount of compression applied to at least one frequency band of the enhanced audio signal. In typical embodiments, the enhancement is or includes bass enhancement. Examples of other types of enhancement performed in other embodiments include dialog enhancement, upmixing, frequency shifting, harmonic injection or transposition, subharmonic injection, virtualization, and equalization. Other aspects are systems (e.g., programmed processors) and devices (e.g., devices having physically-limited bass reproduction capabilities, such as, for example, a notebook, tablet, mobile phone, or other device with small speakers) configured to perform any embodiment of the method.

Audio enhancement in response to compression feedback

A method and a system for dialogue enhancement of an audio signal, comprising receiving (step S) the audio signal and a text content associated with dialogue occurring in the audio signal, generating (step S) parameterized synthesized speech from the text content, and applying (step S) dialogue enhancement to the audio signal based on the parameterized synthesized speech. With the invention text captions, subtitles, or other forms of text content included in an audio stream, can be used to significantly improve dialogue enhancement on the playback side.
