<pre wrap="">Keeping in mind what I wrote above (our goal is seamless switching between files during playback), do you think the variable callback approach would work?

<pre wrap="">
I understand your need here. Question is: How long does it take to load and parse such an HRTF file? Its probably quite fast, and then it should be fine to use a callback. I mean who cares if the switch to the new HRTF file happens only 20 ms after you clicked something in the GUI.</pre>

Not sure if you really want to do so. The parsing will depend on the
size of the file. The free-field HRTFs are usually about 3 MB
(zipped, they will be decompressed on load), see the files from
<a class="moz-txt-link-rfc2396E" href="http://www.sofaconventions.org/mediawiki/index.php/Files"><http://www.sofaconventions.org/mediawiki/index.php/Files></a> The
reverberant files can be in the range of GBs, see
<a class="moz-txt-link-rfc2396E" href="http://www.bbc.co.uk/rd/publications/sbsbrir"><http://www.bbc.co.uk/rd/publications/sbsbrir></a><br>
That's why we currently pre-load three HRTF files, giving the user
the possibility to switch between them on-the-fly.<br>
<br>
BTW, this is a student project and it will end in June. In the
future, having the basic functionality of SOFAlizer available for
everybody, I hope to motivate my future students to further improve
this plug-in, according to your suggestions, of course. That's why
it is important to have a basic functionality included in the
sources. Do you think we can make it? <br>
<br>
BTW 2, SOFA is a new standard for spatially oriented data, see
<a class="moz-txt-link-rfc2396E" href="http://tech.slashdot.org/story/15/03/17/1417216/3d-audio-standard-released"><http://tech.slashdot.org/story/15/03/17/1417216/3d-audio-standard-released></a>.
I am the main developer of SOFA. If you have any question about SOFA
and its use in binaural acoustics, do not hesitate to ask.<br>
