Wheatstone is expanding its blade offerings with the StreamBlade, a WheatNet-IP appliance that accepts up to eight input steams of native WheatNet-IP audio directly from a sound card or AoIP driver as well as RTP sources and can output each in four streams; providing up to 32 total streams per device.
Output choices include Opus, AAC and MP3 encoders. The company says it is cloud-ready and compatible with standard CDN and streaming platforms, including Icecast, Wowza and RTP.
The StreamBlade has onboard processing with a six-band parametric EQ, a five-band AGC, a two-band final limiter and a stereo width control.
Wheatstone says that the AGC is designed for streaming. Jeff Keith, senior product development engineer for Wheatstone’s audio processing line explains, “Fast time constants (compression) can add intermod sidebands around a sustained note or bass note, which the codec has to spend bits on instead of the signals that are actually part of the program. That can be bad for any stream, but it’s especially bad for low-bitrate streams that don’t have a lot of data bits to begin with.”
StreamBlade can be configured and managed from a laptop and web browser using WheatNet-IP Navigator software. The box has two Ethernet ports, one for direct connectivity into the WheatNet-IP audio network on one end and another for connectivity into a WAN for streaming to a CDN or other service provider.
