摘要: The invention relates to a device and method for capturing, encoding transcoding an acoustic field, more particularly three-dimensional comprising consisting of two microphones, means directional analysis said field and, optionally, the field. A first microphone (D1) second (D2) are positioned at distinct locations with orientations. transforms sound waves that it receives into electrical signal, which is digitized create digital audio signal. system performs, every frequency among plurality frequencies, phase measurement signals, as well panorama calculates piece information about direction origin wave. determining magnitude determines, waves. Optionally, on wave is, projected panning law, allowing be transcoded in given format.
