Dear Tony,

It has come to our attention that you've had problems with so called "illegal" Pyramix files. Even if the Merging team did indeed contact you after two days, we thought important to clear up the situation on this forum for the benefit of some other users.

As apple-q states, implementing RF64 would be a logical step, and I've the pleasure to inform you that this is actually the case in Pyramix since years.

To handle the 4GB barrier when recording Wave/BWF, Pyramix transparently switches to RF64 when the 4GB limit is reached during the recording.

You can find on page 311 of the Pyramix User Manual the extract quoted below.

Merging has solved the 4GB problem since the very beginning of its existence by creating the PMF proprietary file format, but as soon as a 64 bits based format has been standardised in the industry it has been supported.

We can only regret that some other manufacturers haven't been as reactive as we always tried.

So, your files are perfectly valid and you can use them in any application supporting RF64.

Hoping this solves and clears up the situation.

Best regards,

Dominique



File Size Limitations:

By design SD2 and legacy WAV or BWF files are limited to a maximum of 2GB, sometimes 4GB due to their 32bit
signed addressing (thus 31 available bits) formats, while 32bits unsigned addressing AIF files are limited to 4GB.

Pyramix's WAV/BWF Media handler now accomodates RIFF64 removing the 2/4GB limitation. It does this in the following
way: Up to 4GB Pyramix creates a regular (legacy) WAV/BWF, but when a recorded media exceeds 4GB, for
example during a recording/render or mixdown, Pyramix will automatically and transparently start creating a
RIFF64 instead of a regular WAV/BWF.

When performing file interchange please be aware that the destination workstation/software must be compatible
with RIFF64 WAV/BWF to be able to read RIFF64 WAV/BWF files.
Similarly, some "old" applications may only recognize WAV/BWF as proper files if their file size remains below the
2GB limit.
