Sample rate 44100 vs 4800?

Hello,

Calling all audio experts.

I'm doing a bit of quality control for a project and I just got the first batch of dailies.

I see the audio has been recorded at a sample rate of 44,100/32 bit.

Now I thought the minimum one should record audio is at 48,000 khz..

My question is this, by it being recorded at 44,100, is that bad?

How big of a quality difference are we looking at vs 48,000?

Does the fact that it was recorded at 32bit, make the 44,100 superior to a 48,000 recorded at 16 or 24 bits?

Thank you
 
You have a music guy doing the recording...

You want either 48/16 or 48/24.

It's not so much a quality thing as having to convert it when you use it. Digital video is 48k and CD's are at 44.1.

32 bit floating is not bad but it's not what you are going to end up at and it may not work in your picture editing software. Even if it does you are probably going to need to convert it to send to sound post.

So IF you are staying inside the NLE and not doing audio post, or this is a music video where you are going to swap in the original at 44.1, AND your NLE doesn't have a problem syncing the 44.1/32 then I would probably stay there so everything is at one sample rate/ bit depth and convert after the edit.

I'm just always nervous about conversions because it's a place you can loose sync and have to work to "fix" it. But we convert all the time now and it's rarely a problem.

In general though you want to keep life simple and 48/16 (or24) is a happy place.
 
As Mr. Koue said, It isn't as much a "quality issue" as a "conversion issue".
And the "conversion issue" has two parts, either or both of which could be significant in your case.

The "hassle issue" of just having to convert everything to the video standard of 48K.
The "risk issue" of trauma to the recorded tracks any time you must convert them.
(Or even later in the production workflow when the audio is further processed and then perhaps compressed for distribution.)

Now you may be lucky and not experience any problems with this, but there are many of us here
who have been burned by these kinds of issues, sometimes much farther along in the production process.
