Vegas Pro and long recording session

DelCallo wrote on 11/7/2008, 4:15 AM

I have long used Vegas (since the Sonic Foundry days) for video, but, for audio only, have tended towards Wavelab (version 5b). I will be recording a classical concert this weekend - expect it to run three hours (on the clock), probably two hours of actual performance.

WL has a switch to overcome the file size limitation. It creates a second file that can be lined up on a time line to create a seamless continuation of the audio when the file goes beyond 2gb in size.

From my video experience with Vegas, I'm guessing that the Wav64 format does this without having to split the file. If I choose to use Vegas to record this performance, must I do anything to invoke the wav64 format, or do I just create audio tracks, arm them to record, and rely upon Vegas to use the wav64 format automatically?

Thanks in advance for any advice you can offer.

Wave 64 is automatically used as required.

Thanks, PCH.

That is very good to know. I've never had problems with long records (the files are split but the project is fine.) To be on the safe side leave it running for 3 or 4 hours and see what happens!

So, perhaps I remain confused. I thought that Wav64 format would allow you to record longer sessions without splitting files. In Wavelab, there is a switch to set and you set what they refer to as the split argument - any file size less than the max at which you want the program to split.

So, if Vegas is splitting files, then, I guess it's not using the Wav64 format - or is it?

The last time I tried to use Vegas (at least a couple of versions back), it kept stopping on me as the file size reached 2GB (fortunately, I was just recording an opera being broadcast over the radio in order to time-shift it in order that my daughter could listen to the performance - didn't work out to well).

As I mentioned before, splitting is not a big deal - the material comes back together seamlessly. I was just (and am still) curious.

Windows has a limit of 2.1GB = 2,097,136KB = 2,147,466,290bytes for a single WAV file, whether it be Mono or Stereo.

This is equivalent to a little over 4 hrs (@48kHz, 24bit) for a Mono file; therefore best to record in Vegas as 2 Mono files, rather than a Stereo file

Correct. Wave64 permits long files. Very long files.

This is done automatically in Vegas. There is no need to set anything.

When you are completed with your recording, Vegas will detect whether the current recording is greater than can be stored into a normal wave file. If it cannot - more than 2 gB in size - it will write a Wave64 header to the file instead of the normal Wave header data.

I just tried this - well I ran a test over night. I got a single large wave64 file. Vegas did not split the recording into multiple wave files.

Are you saying you got multiple files?

I can't swear to it but I thought last time I did long recording there was some split somewhere. It was seamless in the end.
Perhaps my memory is not as good as it used to be, this was also V V6.
