There are options to split recorded mixes at various file sizes. It would be nice to have a check box to disable splitting the file.

I am currently working on the recording engine, and I believe that this should not be an option.

Concretely, I believe that such use cases should use the biggest size, which is 4GB. (Maybe it could be labeled as indicating max allowed size)

Also, it is important to note that due to the way that this is implemented, it only splits the "WAVE" and "AIFF" recorders, because the others are not currently reporting the written size.

Reasons why the 4GB limit should be kept:
the WAV and AIFF container formats that we are using are 32bit. This means that they cannot indicate a size bigger than 4GB.

Ah, I was not aware that WAV and AIFF have a 4 GB maximum. There are alternative PCM container formats that do not have this limit, but they are esoteric and I don't think much software or hardware works with them. However, I don't think FLAC has such a small file size limit (I'm not sure if it has any file size limit). So it would make sense to remove the 4 GB file size limit when implementing FLAC recording:

Now we have the 4 GB Maximum.
The rest will not be fixed, to not risk loosing data.

We have FLAC recording now, so this is still valid. There is no reason a FLAC file needs to be split at an arbitrary file size.

FWIW, in practice I have only ever been affected by this with FLAC once during the longest set I have played (yet) which was >7 hours.

We should add some verbiage that indicates that not all files are split.
