Title: 24/192 WAV length limit ?
Post by: PeterSt on October 21, 2012, 04:29:43 pm
Hi there all,

I just ran into a (for me) weird thing;
I played back a ~40 minute self-recording (from R2R) in 24/192, and 31:04 is the longest time which allows to play. After that it's loud noise (not static).

So, this is for reference at least and for someone who may run into the same problem.

The weird part is : I run into this limit everywhere. And, it is about a "count space" of 23 bits which just fits (so, the 31:04 is representative for that). Now, even when it were about 24 bits, no such limiting "variables" exist in the programming language(s). They can be created, but I don't use them. However, the reserved space in (audio) file headers sure can be limited to 24 bits. So what I think now is that deep down in the audio kernel of Windows (and for WAV ?) this limitation exists. Didn't Google for it yet.
Possibly when I look into the WAV file header I can see the 24 bits space right away ...

This is not related to the 4GB limit of WAV which exists. However, it won't be a coincidence that the limit of 31:04 is equal to 2GB ...
And no, it is also not related to the 2GB of memory limit space which exists for 32bit programs.

Btw, you can already see it by dragging the time position cursor at the bottom of XXHighEnd over that 31:04 limit; it will give you some "overflow" error.

Anyway, my bad or not, this is how it is at this moment for XXHighEnd.

Regards,
Peter

Okay, this is a quite well known thing. Only I didn't know about it. :swoon:
