I carry out sound insulation tests in the UK in accordance with ISO 140. In order to do this I need to have a sound source playing pink noiose through 2 speakers which as guidance on the standard says “must be driven by similar but uncorrelated signals”. In practise this generally means 2 sources.
My question is can one version of audacity running on one pc produce 2 uncorrelated signals? If so what do I have to do to make sure of this?
Note: Cooledit definitely can do this.
