1-24. (canceled)
A method comprising:
- analysing an audio signal ;
- signal processing the audio signal using a first one or more parameter to enhance the speech component of the audio signal dependent on determining the audio signal comprises speech components;
- and
- signal processing the audio signal using a second one or more parameter to enhance the audio signal otherwise.
An apparatus comprising at least one processor and at least one memory including computer code for one or more programs, the at least one memory and the computer code configured to with the at least one processor causes the apparatus to at least:
- analyse an audio signal;
- signal process the audio signal using a first one or more parameter to enhance the speech component of the audio signal dependent on determining the audio signal comprises speech components;
- and
- signal process the audio signal using a second one or more parameter to enhance the audio signal otherwise.
