Download A Simple and Efficient Fader Estimator for Broadcast Radio Unmixing This paper presents a framework for the estimation of the faders gain of a mixing console, in the context of broadcast radio production. The retrieval of the console state is generally only possible through a human-machine interface and does not permit the automatic processing of such information. A simple algorithm is provided to estimate the faders position from the different inputs and the output signal of the console. This method also allows the extraction of an additional unknown input, present in the mix output. An exhaustive study on the optimal parameter setting is then detailed, that shows good results on the estimation.
Download Automatic Alignment of Audio Occurrences: Application to the Verification and Synchronization of Audio Fingerprinting Annotation We propose here an original method for the automatic alignment of temporally distorted occurrences of audio items. The method is based on a so-called item-restricted fingerprinting process and a segment detection scheme. The high-precision estimation of the temporal distortions allows to compensate these alterations and obtain a perfect synchronization between the original item and the altered occurrence. Among the applications of this process, we focus on the verification and the alignment of audio fingerprinting annotations. Perceptual evaluation confirms the efficiency of the method in detecting wrong annotations, and confirms the high precision of the synchronization on the occurrences.
