    Software to encode 5.1 Dolby surround sound for disc or file video being expensive I was wondering whether a cheaper hardware solution might be to use a secondhand DP563 Surround and ProLogic II Encoder, for example. Is it possible to use such a device in conjunction with a PC or is further gear needed? It presents with BNC digital inputs and outputs and I was wondering how this might connect.

    You need a video or audio card in your computer capable of sending out 6 discrete outputs or 3 stereo ones to the encoder.

    You’ll also need to configure your mixer output settings to

    Then you have to play your audio through encoder to another device to capture it, like another computer with video/audio card. However I’m not sure about next step as I don’t know anyone who’s done what you plan. The digital output is the encoded bitstream which is only playable through Dolby decoder, whether on Blu-ray or whatever. I suggest asking this question on one of the Audio groups both here and Facebook. I used that encoder for years, but it was for DVD mastering equipment.

    Encoding is real time, no shortcuts.

    Also you’ll need convertors on the BNC connectors to change to XLR connections unless your audio equipment has BNC. I have some I’ll sell cheap, they’re Canare Impedence Transformers

    Thank you for your response, Bret. This was rather what I thought might be the case. I think I’ll look for a plan B.
