The SONICport and the SONICport Optical, are the two new USB audio interfaces from Opcode. Both interfaces have professional quality analog-to-digital conversion as well as S/PDIF digital connections in either Coaxial or Toslink (optical) formats. These new devices connect externally to any USB-compatible computer for a high-quality stereo, analog-to-digital conversion away from the noise inherent inside a computer. The 20-bit Philips DACs were used to ensure professional quality analog conversion. In addition, the SONICport includes digital coaxial S/PDIF for pure, bit-for-bit digital transfers.

S/PDIF devices include DAT machines, digital multitrack recorders, MiniDisc systems and front-end A/D converters. The SONICport is compatible with 16 and 24-bit systems at 48kHz. and 44.1kHz. Opcode's SONICport simply plugs in and eliminates all the installation nightmares of a traditional PCI or ISA card solution. No cards to install, no IRQs or DMAs to configure, no I/O addresses to set and the host computer doesn't even need to be turned off.
