Method for carrying out a morphing process

Method for carrying out a morphing process, wherein at least one output parameter relating to the output of an audio signal, via an audio output device is changed, comprising:

• supplying an audio signal provided by an audio signal source device to at least one audio mixing device via at least one FIR filter device comprising a plurality of FIR coefficients, wherein 100% of the audio signal is supplied to the audio mixing device via the FIR filter device,
• applying a first transfer function, according to which the supply of the audio signal via the FIR filter device is gradually reduced from 100% to 0% and the supply of the audio signal via a signal processing device connected in parallel with the FIR filter device is conversely gradually increased from 0% to 100%,
• changing at least some of the FIR coefficients of the FIR filter device while supplying the audio signal via the signal processing device,
• applying a second transfer function, according to which the supply of the audio signal via the signal processing device is gradually reduced from 100% to 0% and the supply of the audio signal via the FIR filter device is conversely gradually increased from 0% to 100%, wherein the audio signal is supplied via the FIR filter device on the basis of the changed FIR coefficients of the FIR filter device,
• wherein if an amplification device is used as a signal processing device, the power of the amplification device is set to a value that corresponds to the L2 standard for the impulse response of the FIR filter device, or the power is set to a value that corresponds to an average of the impulse response of the FIR filter device before the change in the FIR coefficients of the FIR filter device or to an average of the impulse response of the FIR filter device after the change in the FIR coefficients.
