Hi all,
In the publication by 3GPP on the noise suppression system for the
AMR speech coder (ts_126077v070000p , pg.27), there's a sentence that
goes like this:
"The environmental noise will be Delta SM filtered to incorporate a
near field microphone response"
What is the 'Delta SM filter'? I tried looking everywhere but I
can't
find any information about it. Anybody has any idea?
Thanks,
Henry
