A method for calibrating a distributed audio reproduction system, including a set of N heterogeneous loudspeakers controlled by a server. This method includes the following steps: a) placing a microphone in front of a first loudspeaker of the set; b) capturing), by the microphone, a calibration signal sent to the loudspeaker at a first time and reproduced by same; c) capturing, by the microphone, the calibration signal sent with a known time delay to the N&#x2212;1 other loudspeakers of the set and reproduced by these N&#x2212;1 loudspeakers; d) capturing, by the microphone, the calibration signal sent to the first loudspeaker at a second time and reproduced again by same; e) repeating steps a) to d) for the N loudspeakers of the set; f) determining a plurality of heterogeneity factors to be corrected for the set of N loudspeakers by analysing the data thus captured; g) correcting the determined heterogeneity factors.
