3.5mm male Stereo jack to 2x 1/4" mono jack female I would like to basically use my macbook to record from 2 sources and I reckon this is an easy way. so the 3.5mm male stereo jack plugs into the macbook and then a mic and acoustic guitar will plug their mono 1/4" jacks into the other end of the cable I would like. Could anyone help me find this cable to buy in the UK please? I've tested this method by wiring up some crappy cables together and on my audio program I can then apply different effects and levels to each mono signal in turn and also make each mono signal into a different joint stereo source to play out both left and right speakers. thanks in advance. Luke.
