1. 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.
