Closing all feature requests.

hello?

Hello?

I know that we haven’t commented on this feature request,
since we are pretty busy people, and you either

1) haven’t read the NoDo FAQ (which tells you that this is
impossible on the Archos jukebox

2) don’t know that we are very early in the iRiver
development and haven’t come close to considering this kind
of stuff

However, the answer is “maybe”. I don’t know enough about
the algorithms involved to be able to tell if the CPU can do
this or not.

Nice idea, but will not work. Even the Philips SBC HN060
Headphone, which has mics *in* the Earplugs, is not that
effective in noise reduction. Try them, they only cost less
than €40.

I have an Altec-Lansing AHP 712i headphone set, it does not work as good as one would hope for treble sounds, but it works well for bass sounds, for example in a train. So maybe, a noise cancellation system would work a little.
