Abstract: An apparatus comprising means configured to: obtain at least one impulse response; obtain at least one reflection filter based on the obtained at least one impulse response, wherein the at least one reflection filter is configured to determine at least one early reflection from an acoustic surface which is not overlapped in time by any other reflection, wherein a duration of the at least one early reflection is shorter than a duration of the obtained at least one impulse response. In addition, an apparatus comprising means configured to: obtain at least one impulse response, wherein the at least one impulse response is configured with a perceivable timbre during rendering; create a timbral modification filter; obtain at least one audio signal; and render at least one output audio signal based n the at least one audio signal, wherein the at least one output signal is based on an application of the timbral modification filter.
