Combining audio components that use incoherent sample clocks requires adaptive resampling - the exact ratio of the sample frequencies is not known a priori and may also drift slowly over time. This situation arises when using two audio cards that don't have a common word clock, or when exchanging audio signals over a network. Controlling the resampling algorithm in software can be difficult as the available information (e.g. timestamps on blocks of audio samples) is usually inexact and very noisy. This paper analyses the problem and presents a possible solution.
