Have you checked whether the evidence that you are preparing is going to be admissable in the first instance? I`m obviously not suggesting that you would use such underhand methods, but it would be trivial to monkey around with the sound or use some other similar technique for altering the evidence.

I remember reading somewhere a few years back about how the police were developing special digital cameras that watermarked the images, if they didn`t it would be far too easy for someone to argue that the image had been tampered with.
