why only first and last channels have signal , are you using mono wav ?

 * The algorithm works basically like this:
         *
         * 1) Connect all channels with matching names.
         *
         * 2) Mono Handling:
         *    S:Mono: Copy into all D:channels
         *    D:Mono: Avg all S:channels
