Resampling and encoding in one or two steps

I use convert to resample a file (using the SoX plug-in under processing) and store it as a FLAC file in one step and in a second step, convert that FLAC file to a lossy file.

If I convert to a lossy file with resampling using the same settings in a single step, I notice the two files are different with bit-compare. I'm curious. Shouldn't these two files be exactly same?

Oh, I meant to post this under General.

no, they should be different.

What's different?

If you convert in 1 step, intermediate results have 32-bit float bit depth.

If you use FLAC then intermediate results have 24-bit (or even 16-bit, depending on your settings) bit depth.

Very small difference, but it's not 0.

I see. Thanks for the info.
