I want to implement active noise cancellation algorithm for headphones. For that i m using ADAU1701.I want little help about deciding which algorithms i can implement in this processor.
A full list of the algorithms supported on the SigmaDSP can be found on our algorithms page. If you'd like to try to implement your signal flow, you can request a download key for the SigmaStudio tool from firstname.lastname@example.org. With this, you should be able to pretty easily see what you can implement on the ADAU1701.

thats a great link. Is it new ? Is it finished ?
Some of the submenu items give a descriptive text at the bottom of the page, but some dont.
the main section on the right side never changes, it just shows the sigma dsp logo.
Still it nice to see all the algorithms in one place. thanks

Yes, this is a new page we just recently launched. It will be continually updated as new algorithms are added to the library. We may also be adding more descriptive text in the right panel, but for now we just wanted to start with listing all of the available algorithms.
Further documentation on all of these blocks is available in SigmaStudio's help file, included with the software download.
I am looking forward to implement least mean square (LMS) algorithm for noise cancellation. It is not present in available algorithms .How i can add my own blocks in Sigma Studio.Even I don't found How to add my own variables.Is it possible to write C code and convert it into block?
We do not support adding your own blocks in SigmaStudio. SigmaStudio includes a library of low-level signal processing functions, such as adders, multipliers, feedback, and delays. These can be wired together to create a custom algorithm within SigmaStudio without having to write line-level code. There is not a C compiler for the SigmaDSP processors.
