Jeff Hurchalla, our new President of Garritan, will be making a technical presentation at AES in San Francisco tomorrow, November 12 at 2:30 pm.
The title of his talk is "A Time Distributed FFT for Efficient Low Latency Convolution"
Here is a link to the presentation http://www.aes.org/events/129/papers/?ID=2391 and the talk is about:
"To enable efficient low latency convolution, a Fast Fourier Transform (FFT) is presented that balances processor and memory load across incoming blocks of input. The proposed FFT transforms a large block of input data in steps spread across the arrival of smaller blocks of input and can be used to transform large partitions of an impulse response and input data for efficiency, while facilitating convolution at very low latency. Its primary advantage over a standard FFT as used for a non-uniform partition convolution method is that it can be performed in the same processing thread as the rest of the convolution, thereby avoiding problems associated with the combination of multithreading and near real-time calculations on general purpose computing architectures."Jeff's convolution algorigthm promises to benefit the industry.
If you happen to be at the AES show in San Francisco, please be sure to see Jeff's presentation.
