WAVERSA SYSTEMS INC.
Waversa I2S Direct Renderer (WIDR)
• Waversa's proprietary standard that overcomes the limitations of SPDIF PCM transmission
• Transmit WAP data together without any other procedure, dramatically improving sound quality
• DSD transmission possible without going through DoP format
• Significantly lowered audible noise
All new Waversa products incorporate a new technology that allows you to experience DSD, WAP settings, and even lower noise all at once. WIDR capability will be provided to most equipment already in the field via Waversa internet update. Only the VDAC, DAC3C, and DAC3 will require manual programming. When the new software is available, notice will be provided to owners to make arrangements for manual updating.
WIDR (Waversa I2S Direct Renderer) is an I2S-based proprietary transmission technology that can be used when connecting to a Waversa device that supports the protocol. Unlike existing I2S methods, which require a separate terminal and cable to transmit the clock and signal separately, Waversa's unique core technology allows more information, including both clock and signal, to be transmitted through the existing Coax terminal.
WAP Data Transmission: Unlike PCM, which supports up to 24bit/192kHz, WIDR is transmitted at 28bit/192kHz, making it possible to transmit all the WAP processing information.
Original DSD support: Unless you have a player with a built-in decoder or a device capable of dual digital output, you may have experienced at least once that you could not enjoy DSD sound sources smoothly. Even without these complex devices, the transmission was usually only possible via DoP (DSD over PCM). WIDR is a completely different standard from PCM, and it can transmit the original DSD signal with a single Coax cable bypassing DoP.

Bottom measurement notes noise floor without a source connection.
Low noise floor: Unlike SPDIF, which always generates a signal continuously in all sections, WIDR transmits a signal at high speed only in the section where there is data and does not send a signal in the rest section. Therefore, it always maintains a low noise level compared to SPDIF, which inevitably has to maintain a high noise floor state.
