Hello,

I was wondering why the rarewares "LAME 3.99.5 using libsndfile 1.0.25" x86 and x64 compiles give different results (mp3) with the same source file (flac) and options. The difference is very settle (4 bytes) but the audio stream is different when bit-compared with foobar2000.
Shouldn't the audio stream stay the same?
Maybe john33 could check on that?

Edit: The title got truncated. It should have been -> different results with rarewares "LAME 3.99.5 using libsndfile 1.0.25" x86 and x64 compiles

I just selected all four, foobar2000 divided the two.

Tested again:

Is that 0.022 relative to 1? If so, it's larger than the difference one would usually expect between 64-bit vs. 32-bit compiles (e.g 1 LSB at 16-bit is 0.00003).
