Non-linear audio system errors can be analysed by separating the composite error characteristic into linear and non-linear components and then modeling linear artifacts using MLS techniques. Flexible choice of measurement nodes and the use of music signals as system input excitation results in a digital difference test which is capable of real-time non-linear error analysis and overcomes limitations in previous measurement strategies.
