Good evening vs planeteers! I'm collaborating on a project with some friends from another band in England.. I just got a email asking me which sample rate I prefer.. I've recorded all the information on the via 1680 at 44.1 but it's my belief that once you convert that to a WAV file the sample rate is somewhat less important. IE all wav files are compatible.. am I thinking about this correctly before I answer his question?

By the way, I'm recording in a vs 1680, and assembling wav files from my collaborators and wav files that I create through Virdis in Reaper where I will do the mix.. so it won't be a question of needing to import it into the 1680.

Any wav files you create with VirDIS/VSWE will be the same sample and bit rate you originally recorded them at in the 1680. If you record in MTP mode, the bit rate is 24 bit (the highest the 1680 can do) - the sample rate will always be whatever you set up when creating the SONG project. So, if you always use 44.1k AND record in the MTP mode, then you will have 44.1k/24bit wav files upon conversion in VSWE.

MT2 mode is 16 bit, as are most of the 1680 record modes. The original idea was that if you recorded 44.1k in MT2 mode, you would be creating SONGS that were at the appropriate specs for standard audio CDs - which is 44.1k/16bit.

All wav files may be considered "compatible" as you say, when they have been imported into a computer daw that does its own real time sample rate conversion - so you could potentially mix say, 44.1k and 48k wav files.... the sample rate of the files "should" match that of the project and sometimes this may require a resampling to match. If sample rates don't match, there's potential problems with playback speed.

The bit resolution is somewhat less of an issue than the sample rate and can be handled mostly by just setting the daw project bit rate to the desired resolution, regardless that of individual wav files... Ideally, everything would match.

Recording at 44.1k is not a "bad" thing, no more so than recording at 96k is the "best" thing. It depends on the project, style, instruments, destination playback, etc., etc.
But it saves a lot of hassle if all tracks are recorded at the same sample rate at the outset.

Thanks Dan for your continued brilliance for us here!! That's EXACTLY what I was trying to apprehend.

I record at 44.1k and 24 bit, and another collaborator so far provided me tracks at those rates (WAV files) and it all lined up.

Interestingly, you point out that playback speed might be trickier if combining different sample rates. We found this to be true also when I sent stereo mp3s as guide tracks...the WAV files I got back we're not staying in time...I quickly sent off WAV L and R tracks as guide tracks and the parts came back perfectly in sync. I had thought it was a digital clock anomaly, but now I think the glitch in playback was more a sampling issue?

Thanks so much, once again!,
