While Thesycon keeps their proprietary source code private, several academic papers analyze the performance of ASIO drivers, specifically citing Thesycon's implementation as a benchmark for low-latency performance. These are the definitive technical documents written by
The RME Babyface Pro utilizes Thesycon's driver core but customizes it with RME’s TotalMix FX DSP engine. Here, Thesycon provides the low-level USB transport and ASIO COM interface, while RME adds hardware-accelerated mixing. This hybrid model demonstrates the flexibility of Thesycon’s layered architecture.
Windows 10 and 11 introduced WASAPI Exclusive Mode, which offers latency as low as 3-5ms without third-party drivers. Some modern DAWs now support WASAPI.
