I just came home from a recording project in St. Petersburg Russia with a hard-drive full of Pyramix polyphonic wav files. They played fine on the Pyramix system in St. Petersburg but they do not play on anything home here in the UK, except maybe another Pyramix system (which we do not own). We have two SADiE workstations also Sony Vegas and Adobe Premiere Pro (64bit) all of which report the big Pyramix files as ""unsupported format or damaged file".

Anyone got any tips? The 'illegal' Pyramix files are sixteen-channel 88k2/24 polyphonic wavs and most are larger than 4GB. I guess I need to split the polyphonic files into mono wavs. WaveAgent can only cope with up to twelve channels. BWFSplitter reports the 'larger than 4GB' as invalid.

I contacted Pyramix but they have not replied. My understanding is that a wav file is a RIFF file with 32bit addressing so 4GB is the maximum amount of data which can be addressed. I have heard of possibilities for a wav64 format, but these big Pyramix files larger than 4GB just appear to be some kind of in-house bodge which only works on Pyramix workstations.
