Most of the familiar multi-channel sound that we hear; stereo, 5.1, 6.1 etc, is produced in post-production. Multiple (usually mono) sound sources are mixed and tweaked to produce the surround-sound-extravaganza that we know and love. Well Holophone do things a little differently, they make a range of 5.1 surround sound microphones, including the PortaMic 5.1, that can record 5.1 sound using a single mic.

The PortaMic 5.1 sits on the microphone accessory shoe of high-end camcorders and lets you record 5.1 sound as either a final mix or into its discrete channels. The audio is encoded into Pro Logic II and can be decoded back to 5.1 in post so you have the choice of keeping it all or leaving it as stereo. It weighs 400g, (~1lb) and needs a 9V battery which will keep it running for around 3 hours. Price is around US$599.
