Latest Patents

One of Joly's latest patents is a method for qualitative evaluation of a digital audio signal. This invention relates to a technique for assessing the quality of a digital audio signal by calculating a quality indicator. This indicator consists of a vector associated with each time window in real time and in continuous time. The method generates a quality indicator vector that calculates the spectral power density of the audio signal, the coefficients of a prediction filter using an autoregressive method, and the temporal activity of the signal. Additionally, it evaluates the deterioration of the audio signal by calculating a distance between the vectors of the reference audio signal and the audio signal to be evaluated.
