Lawo VSC
Virtual Audio Device and App for macOS
A virtual audio device for macOS, Lawo VSC runs as a service without constraints beyond those imposed by the hardware, turning your local audio into clean, pristine RAVENNA/AES67 streams that can be shared on any AoIP network, and allowing you to receive audio streams.
Modern broadcasting and audio infrastructures rely on AoIP networks, multi-channel audio as well as desktop and laptop computers. Lawo VSC is a powerful audio application designed specifically for macOS Sonoma (Version 14) and beyond on Apple workstations and laptops.
Supporting sampling rates of up to 96kHz, Lawo VSC is pure software built around a professional, low-latency driver with up to 128 audio channels per virtual audio device. On the network side, Lawo VSC carries uncompressed, bi-directional audio channels for up to 128 streams per virtual audio device—either in multicast or unicast mode.
Connect Lawo VSC with any studio hardware or software
With Lawo VSC, users can connect any studio hardware or software they choose from the ever-expanding RAVENNA/AES67 universe. Open AoIP standards, including SMPTE ST2110 for audio transport and ST2022-7 for redundant setups, are also supported, turning Lawo VSC into a Swiss Army knife for a variety of professional audio and broadcast applications.
Lawo VSC is available in two versions. The free version, available for download from Lawo’s website, supports 1 virtual audio device with 2-channel senders and receivers on a single network interface. The Standard version of Lawo VSC provides the features described above and below. Lawo VSC supports both light and dark modes.
