C tuning samples - best methods

Hi all, sorry if this was covered elsewhere, I couldn’t find a topic for this but what are your best methods to tune your samples in C for use in the Play ?

It would definitely be cool if imported samples into Play were automatically repitched to C, it may work if the sample original pitch is already known and in the sample name, but for samples where the pitch is unknown i’m not sure if this would be possible.

You could use something like https://mixedinkey.com/ which will detect what key all your samples are in but you still need to repitch them after that, not sure of any software that detects and repitches to a given note automatically.
