1.4beta9: Replaygain scanning 24bit files produces info line "Automatic resamp"

fb2k 1.4beta9:

Does the Replaygain scanning process need redbook (16/44.1) audio files?
When replaygain scanning 24-bit files the scanner produces info line: "Automatic resampling: using Resampler (PPHS)".

This info line seems to be new since 1.4betaX

Sounds like you have true peak scanning enabled. It works by upsampling to higher sampling frequency so that actual waveform shape going to the DAC can be estimated. And the info line is a new addition introduced with the resampler service changes.

Thanks, Case, for your reply.
No, peak scanning was not enabled but "Downsample high-definition content" was enabled - using [chose automatically].

Sorry for being too lame to explore this, myself... ;)

Downsampling high-definition content is mostly so that ultrasonics don't screw up the reported volume levels.
