Several multichannel audio formats are present in the recording industry with reduced interoperability among the formats. This diversity of formats leaves the end user with limited accessibility to content and/or audience. In addition, the preservation of recordings—that are made for a particular format—comes under threat, should the format become obsolete. To tackle such issues, we present a layout-to-layout conversion tool that allows converting recordings that are designated for one particular layout to any other layout. This is done by decoding the existent recording to a layout independent equivalent and then encoding it to desired layout through different rendering methods. The tool has proven useful according to expert opinions. Simulations depict that after several consecutive conversions the results exhibit a decrease in spatial accuracy and increase in overall gain. This suggests that consecutive conversions should be avoided and only a single conversion from the originally rendered material should be done.
