Abstract
We propose a technique of signal acquisition using a combination of two devices with different sampling rates and quantization accuracies. Subsequent processing involving sparsity regularization enables us to reconstruct the signal at such a sampling frequency and with such a bit depth that was not possible using the two devices independently. Objective and subjective tests show the superiority of the proposed method in comparison with alternatives.

Comments
This preprint has been withdrawn by the authors since the experiments have been found to contain somewhat unfair comparison between the proposed method and the others. Authors work on another paper containing a new experimental section
