downsampling PCM

thanks to help from the forum my volumio / Odroid C2 is now up and running and sounds great.
Is it possible to downsample i.e. 352.8kHz PCM to 176.4kHz, as my DAC only accepts up to 192kHz and I have several 352.8kHz FLAC files.

I am aware that the processing power of the Odroid C2 is probably not up to things like transcoding DSD to PCM on the fly, but an integer based downsampling of PCM should not use a lot of processing power. Is this possible?
