It makes bigger files without adding independent information, and
freezes the level of technology used - thus storage and archiving are
completely
Hello,
did anyone do a comparison between HarpexB, O3A Harpex Upsampler and
SPARTA COMPASS to see which produce a better and more precise output? Or
is it just a matter of personal taste and any engineer can choose
preferred one?
Personally I think upsampling is a great option, mainly for
Hi All ,
Thanks for all the help Archontis, Axel, Steve and David. This topic just
got more exciting for me. Yes I am aware of Harpex, Blue ripple and Compass
that's on the market, but I guess I need to study and be more aware of what
I am reading for my secondary research.
Many Thanks,
Wilson
Interesting question David.

Hi David,
These upmixing methods extract a lot of information from the FOA recording that
is then re-used to essentially “synthesize" the HOA signals, with a spatial
resolution that would not be possible with the FOA recordings. They are
“active” in that sense, and signal-dependent, compared

Not directly.
But one can create a lot of beams (without the rear lobe), to up mix with…
One needs a few instances depending on the order you want to up mix to, but I
have had good results from it.
It is uses some form of adaptive parametric/directional analysis.

Hi Steven,
As far as I remember the Rode plugin does not offer this functionality
(upmixing FOA to HOA).

And lets not forget ‘Soundfield’ by Rode.
This also uses some form of parametric direction detection. Either on B-format
directly, but also on the Rode’s A-format.

Oh my mistake then, I thought the HARPEX vst was doing direct rendering only,
and its HOA upmixing functionality was done

Three it is then :-).

To add on top of the previous email, there are three then ( I didn t know
about COMPASS), because Harpex can be a vst itself, which sounds
magnificently good.

Hi Wilson,
First of all you have to understand the upmixing algorithms themselves before
starting implementing them. Some methods that can do that are Directional Audio
Coding (DirAC), which you can read all about in the “Parametric Time-frequency
Domain Spatial Audio” book of last year, and
Hi Everyone,
Not sure if I have missed a discussion about upmixing with ambisonics on
Sursound.
Just wondering if anyone is willing to share some information on how to
implement upmixing algorithms from 1st Order Ambisonics A to 3rd
Order Ambisonics B-format.
I am really curious to know on how
