Export to MP3 - track is slightly detuned?

[DavidPardy]

Just wondering if anyone has encountered this problem before? I didn't have time to do much testing but I had a few goes and basically it's exactly what it sounds like - I export an MP3, and the whole thing is running at a slightly lower pitch than it is meant to - sounds awful, to be honest.

I tried with dithering on and off, and exporting at 1x Playback speed.

I'm not sure what triggered the change as I made a couple of changes plugin-wise between exports. I added a second track utilising a Sforzando + volume and pan rack, added the "dreamy guitar" plugin rack preset to that track, and added a compressor to another track.

I'm running an i5-8400 with 16gb RAM, and I've exported more complex tracks with recorded audio before with no trouble - this is a purely MIDI setup.

Playback in the DAW itself is fine.

Any advice would be most welcome I haven't had the chance to try exporting to WAV or anything else just yet

just hazarding a guess but sample rate mismatch? eg mp3 player running to your soundcard at 44.1K but file/original project was 48K?

Hmm, thanks for the tip. I'm not sure why that would have changed between the changes but I'll make sure!

Thanks, that seems to have fixed it! All the settings worth 48khz apart from the MP3 dialog which was 44.1k, tested a new export on both settings and setting it to 48khz fixed it. I must have changed it without realising. Thank you!
