I would not say it is a 'bug' based on my test.. Encode times normally vary from version to version. 500 seconds is a l o n g time for sure.
My results encoding a one minute (60 sec.) stereo 44,1/16 PCM file to MP3 (44.1kHz, 320kbps, stereo, CBR, highest quality)

Hi Rick, thanks for the help. I did a test: 1) I formatted the computer. New Install of Windows 10 64 bits. 2) I installed SF 13 64 bit. 3) I made a recording in .mp3 -> It was fast. 4) I installed preset manager (presetmngr20k.exe) 5) I installed NRP (Noise_Reduction_Pack_2.0.0.1318_INT_x64_180710.exe) 6) I made a new recording. This time it was slow, very slow. 7) I uninstalled everything (SF, NRP, Presetmngr) 8) Reinstalled SF, again very slow.
Do you have processes and/or plug-ins running or just a straight MP3 encode? What format is your source file? What is the duration (length) of the source file? What exactly are your MP3 encode settings? "I made a recording in .mp3".... Does that mean you recorded something live?
I found out when the bug appears: If I open a .mp3 file and modify a lot, (graphic equalizer, volume ...), it saves normal. But if I cut (remove) a piece of music, just two seconds, it takes too long to save.
Eu Descobri quando o bug aparece: Se eu abrir uma arquivo .mp3 e modificar bastante, (graphic equalizer, volume...), salva normal. Mas, se eu cortar (retirar) um pedacinho da música, dois segundos apenas, ele demora muito para salvar.
This bug is also present in SF 14.0.130. A music file in mp3 format. If I cut a piece of music, recording on SF 32-bit is very fast. But in SF 64 bits it is extremely slow. If you open the music file and modify, for example, the equalization, it keeps recording fast. It is more advantageous to always record in .WAV format and use a converter program, such as Factory Format, freeware.
