Huron-A Digital Audio Convolution Workstation

After several years of development of audio DSP processors, the demand for complex DSP systems with multiple channels of I/O has led Lake DSP to create a digital audio convolution workstation. This system, known as Huron, is intended for use in research areas of audio, where a large array of parallel DSP processors can be used to process multiple channels of real-time audio. The Huron system is built around a powerful host processor with an integral bus that allows 256 channels of audio data to be passed between DSP processors and I/O modules. I/O options include A/D and AES/EBU digital I/O. Huron is also the first platform available that uses the zero-latency convolution algorithms, developed by Lake, for real-time audio processing with ultra-long FIR filters, up to 262144-taps on multiple channels. The Huron system is capable of rapidly updating long FIR filters to allow real-time animation of complex effects. The main applications addressed by Huron include 3-D virtual reality audio, accurate reverberation, equalization, and multichannel mixing for studio or sound reinforcement systems.:
