Acoustic Echo Cancellation using Unconstraint Partitioned Fast Block LMS [2 Attachments]

Howdy Karthikeyan,

While I like the way your code is written to be concise, it's not so easy to debug. Break up the calls so you can see all the intermediate terms, and dump them to an array so you can see what is happening over time. Is it oscillating or limiting in the wrong direction? At what point does it "go off the rails" to not converge?

Once you see where the problem is, it's usually pretty easy to fix.

Patience, persistence, truth,
Dr. mike
