Default 96k FLAC in a 48k session

Newbie here, but I need to check this:

I have what appears to be a 96k FLAC file, open in a 48k 24-bit session. Its playing fine, apparently at the correct pitch, and Reaper didn't convert it anywhere to 48k 24-bit.

Is this correct? This is pretty stellar if it's playing a 96k FLAC file natively in a 48k session.

Hi,
if it is really 96k, Reaper is converting file at item level, before mute at signal chain.
- you can check original sample rate by right clicking and selecting Source properties
- if there is rate conversion at place, you will see small rectangle icon with "i" letter at top left corner of item. If you place mouse cursor over there, you'll see tooltip, which will state "Resampled from ..original rate"
- realtime rate conversion is good for preview, you can adjust quality at project settings. There are two settings, one for realtime playback and second for rendering of final file.
- my recommendation for production is to convert it offline as you can choose much better quality and don't have to look at CPU drain. Check File/Batch Item Converter and use Extreme quality preset with dither checkbox on.

Great info - thanks! Yep I see that "i" on the clips now.

FWIW I'm really glad it CAN do this. I don't always want files to be converted just for simple edits (pre export) and working with them. And I store a lot of my library in FLAC these days.
