Dear all,

A new Spat version is available for download.

Below is a recap of all the changes since last year (bug fixes, new features, new objects).
Please be aware that there are few compatibility breaks with previous versions; it should be rather straightforward to upgrade your patches though.
Feel free to ask questions.

****************************************************************
Release Version : 4.7.4
Release Date : 05/2014

* fix possible crash with spat.eq~.control
* fix possible crash with spat.sfrecord~
* spat.pan, spat.pan~ : changed the “spread” law.
* spat.pan : removed attribute ‘interpolationtime’ which was useless
* spat.pan : fix bugs with ‘vbip’ and ‘vbip2d’ panning types
* spat.pan : ‘type’ attribute can now be dynamically changed
* spat.distance : added ‘type’ attribute
* spat.spat~ : fix possible freeze upon initialization of the object with vbap or vbip panning
* added spat.smpte~ : decode LTC to produce SMPTE code (based on Andrew Gerzso’s developements)
* spat.pansig~ : fix possible crash when initializing the object
* spat.pansig~ : added signal inlet for spread (rightmost)

****************************************************************
Release Version : 4.7.1
Release Date : 03/2014

* spat.viewer : fix minor bug with ‘height’ attribute
* spat.pan~ : fix bug with knn panning when numneighbors = numspeakers
* spat.viewer, spat.viewer.embedded : added attribute ‘defer’ : this determines the behavior of the graphic refresh.
The value ‘defer = 1′, corresponds to the operating mode in previous versions :
each message is deferred and triggers a refresh. The low-priority queue may become backlogged
and the UI irresponsive if the messages rate is too high.
With ‘defer = 0′, messages are not deferred, and the UI refresh is queued until the next service of the
low-priority thread.
NB : The default value is ‘defer = 0′
NB : This DOES NOT work yet for spat.oper or other GUI objects
* all objects : avoid crashes when loading corrupted or weird audio files

****************************************************************

Release Date : 02/2014

* spat.viewer : added message ‘adjustzoom’

* spat.sfplay~, spat.sfrecord~ : added supbport for WAV RF64 files
(WAV extension for files larger than 4 Go; the new maximum filesize is now approximately 16 exabytes)
* spat.viewer / spat.oper : deprecated messages like ‘source 1 30 1 0′ (index azimuth distance elevation).
The format identifier (e.g. ‘source 1 aed 30 1 0′) is now mandatory.
* spat.hostinfos : added ‘folder’ message to retrieve the folder of the current patcher
* added spat.fileinfo : retrieves various infos about files
* added spat.zpplot : plot poles/zeros of a cascade of biquads

spat.transform comes as a replacement of spat.translate and spat.rotate which will be deprecated
* spat.spectroscope~ : added ‘smoothing’ attribute; added ‘fill’ attribute; added messages to ‘fill’ and ‘show’
each channel individually.

* spat.meter~ : added ‘clearsolo’ message
* spat.knn : fixed bug when numneighbors > 1
* spat.pan, spat.pan~, spat.spat~, spat.pansig~ : added new panning type : ‘knn’. This performs amplitude panning
on the k-nearest loudpseakers (somehow similar to dbap then) (alpha version)
