How to use convolution with DSD files

[john (John Iburg)]

Hello @Hans_Stahlhelm,

In regards to Roon’s DSD Engine native DSD processing capabilities, I will refer you to this post by our CTO explaining how this feature works from a technical perspective

Native DSD processing

Unlike with PCM, processing 1-bit DSD signals in their original form is not practical because 1-bit signals do not have enough dynamic range to perform common operations like volume adjustment, eq, mixing, or convolution directly on the 1-bit representation. So when DSD IS processed, the input to the processing chain is a 1-bit DSD signal, but the output must have more dynamic range. In Roon’s case, we perform processing with 64-bits of precision, so whenever you process DSD, you end up with so…

In the case of using convolution filters with native DSD processing, we will resample the filter to the native sample rate of the DSD file in accordance with the strategy above.
