Andrew also shares some details about his work developing authentic-sounding emulations of classic analog vocoders that we’ll see in upcoming Antares products. We sat down with Antares DSP engineer Andrew Kimpel to learn about the history of these two iconic effects, how they work, and what they sound like.
