cosm.ambi.decode~ External Decode a summed bus of encoded ambisonic signals for a user-specified speaker layout.
hoa.dac~ External An ambisonic audio output.
hoa.dac~ makes easier the setting of the channels. It works like a dac~ object but you can use the matlab syntax ":" to set the loudspeakers routing.
hoa.decoder~ External An ambisonic decoder.
hoa.decoder~ decodes an ambisonic soundfield for a given number of loudspeakers.
hoa.meter~ External A sound field meters and descriptor UI.
hoa.meter~ displays the peak levels for a circurlar array of loudspeakers. It computes and displays the energy vector. The number of loudspeakers is defined at the object creation with the attribute @ls and the offset of the loudspeakers is defined with the attribute @offset (ex : hoa.meter~ @ld 16 @offset 0.5).
hoa.projector~ External An ambisonic projection external.
hoa.projector~ discretizes the ambisonic soundfield into an array of virtual loudspeakers and gives a access to a new sound domain.
zsa.freqpeak~ External Extract a list of pairs Frequence/Amplitude
-peak External is a negative peak (it could be called borders)
aka.speech External speaking a text (text to speech)
This object reads a loud text.
ambi.decode~ External Decodes an ambisonic encoded sound field to a user-defined speaker array of up to 16 channels (more can be added by using more than one ambi.decode~ object).
Messages control the speaker layout, global gain, mono/spatialized balance, and decoding flavour.
Ambi2Bin~ Abstraction Converts from ambisonics to Binaural.
You will need an ambisonics decoder to decode to 7 speakers (6 speakers horizontal symetrical ring and one speaker on top).

The patch convolves the speaker inputs with the apropriate impulse responses from the MIT HRTF IR collection.
ambicube~ External ambicube~ is a 3-dimensional version of ambipan~.
ambicube~ is a flexible MaxMSP and Pure Data external object providing surround panning for sound sources in multi-loudspeakers environments thanks to Ambisonic techniques. It is possible to use both signal and control data to feed the object, to switch dynamically between several setups (number and position of loudspeakers). It is also possible to use either polar or Cartesian coordinates.

comb1~ Abstraction comb filter
A comb filter creates equally spaced peaks or troughs in the output signal's frequency response at each multiple of the peak width (a frequency value in Hz). This is done by adding a slightly delayed version of a signal to itself, which causes regularly-spaced phase cancellation in the signalís spectrum. Negative values for the intensity parameter cause the center frequency of all peaks to be shifted by half the peak width (i.e. the troughs occur at each multiple of the given width). The comb1~ module is a basic FIR (finite impulse response) comb filter which is much simpler than MSPís standard comb~ object. Usually, more than one comb1~ will be needed to produce enough volume for any musically useful filtering effects (it has a potential gain of 2).The help file shows how its gain may be boosted by connecting three (or more) in series.
cretmet~ External get the signal peak level (dB and linear)
DeltaT Collective Graphical interpolating delay/panning tool for arbitrary placed loudspeakers.
This is a small collective to enable the user to test delay/panning settings on arbitrary placed loudspeakers really quick.

It consists of a pattrstorage to provide the model and calculation, a small script to add new sets of delay/gain/pattr-objects and a js + jit.gl patch to graphically control the placement of the presets and the interpolation.

A small tutorial will be uploaded in the near future.
