An efficient method and system to enhance digital acquisition devices for analog data is presented. The enhancements are available to the user in local as well as in remote deployments yielding efficiency gains for a large variety of business processes. The quality enhancements of the acquired digital data are achieved efficiently by employing virtual reacquisition, which renders unnecessary the physical reacquisition of the analog data in case the digital data by the acquisition are of insufficient quality. The method and system allows multiple users to access the same acquisition device for analog data. One or more users can virtually reacquire data provided by multiple analog or digital sources. The acquired raw data can be processed by each user according to his personal preferences and/or requirements.
