Abstract Dynamic range compression (DRC) of simple signals results in harmonic nonlinear distortion. However, for summed and more complex signals, predominantly intermodulation distortion (IMD) is generated, causing artefacts which are not harmonically related to the source audio. There are a number of methods and approaches for applying DRC to audio and music signals and, in particular, this research compares the methods of compressing signals prior to and after summation. The research therefore evaluates approaches for minimising the level of IMD in compressed audio signals. Results show that lower IMD values are achieved by applying compression prior to summation.
