Abstract
A method and an associated device for the combined conversion of multiple characteristics of an audio signal are disclosed. The changes allow the signal to be typed on the basis of a profile selected by a control unit. The method and the device are particularly intended for the field of loudspeakers.

A method for transforming an audio signal for an electro-acoustic transducer, comprising:
- wherein said audio signal is modified in a combined manner using a plurality of audio signal characteristics as a function of a typical profile selected by a control module, to provide specific characteristics to the audio signal, said audio signal characteristics being selected from the list including:
- gain, phase, time, distortion, bandwidth, bandwidth distribution per speaker, dynamics compression/expansion, directivity, sampling, absolute phase corresponding to the electrical polarity of a group of loudspeakers at the impulse response, displacement of the reference point where all frequencies are in phase, and wherein the control module automatically adapts the selection of a typical profile as a function of the information of the determined musical style of a music track, the selected typical profile comprising settings of the electro-acoustic transducer relative to the audio signal characteristics.
A device for transforming an audio signal for an acoustic transducer, comprising:
- wherein the device is configured to modify said signal in a combined manner using a plurality of signal characteristics as a function of a typical profile selected by a control module, to give specific characteristics to the audio signal, said audio signal characteristics being chosen from the list comprising:
- gain, phase, time, distortion, bandwidth, bandwidth distribution per speaker, dynamics compression/expansion, directivity, sampling, absolute phase corresponding to the electrical polarity of a group of speakers at the impulse response, displacement of the reference point where all frequencies are in phase, and wherein the control module automatically adapts the selection of a typical profile as a function of the information of the determined musical style of a music track, the selected typical profile comprising settings of the electro-acoustic transducer relative to the audio signal characteristics.
