Switch project sample rate to 48 kHz? [SOLVED]

[dapacarter]

Hello can you help

 

I have recieved stems from my co producer and when I import the stems into a new Logic session I am asked the following

 

"the added audio files has a different sample rate. Would you like to use it for this project? click no to keep the current sample rate of 44.1 kHZ?"

 

when i play the session there is no audio at all

 

my co producer uses Sonus and I am on the latest edition of Logic Pro with the Apogee Ensemble...

 

we have been working like this for over a year and I have never been asked about the sample rate before and I have never had an issue with importing the stems into a new session.

 

Any help out there?

Why not just switch the sample rate of your Logic session before loading up the stems?

[dapacarter]

that is what I am doing and I am not getting any audio from the stems?

[David Nahmani]

Are the stems on audio tracks? You should get audio whether or not the sample rate is correct - only in one case they'll playback at the correct pitch/speed while in the other they will be sped and pitched up or down.

[dapacarter]

yes its wierd all the tracks are audio not midi i dont understand it

Do you see level on the meters when you hit play?

[dapacarter]

no level on meters it is very strangeand only happens the latest imported stems never happened before and all other sessions work perfectly

Please post a screenshot of your Arrange window with one of those non-playing track selected.

 

Also please add your Logic version and system info to your signature: Forum Rules - please READ THIS before posting (#5)

This is kind of a longshot, but I have a similar problem sometimes as well.

In my case it seems to be related to my MOTU software and/or hardware and its communication with Logic.

Sometimes when switching sample rates (of either a project or a file), doing sample rate conversion, toggling between Final Cut 7(which is usually operating at 48K) and Logic (often 44.1K), or switching the wordclock source, Logic will stop producing any audio. I won't see it in the meters, and no sound will come out. In my case, 80% of the time going to the MOTU Audio Setup (a little app that manages some settings for the hardware such as sample rate, clock source, output selection, etc.) and toggling the optical I/O to ADAT or None, then back to Toslink (my default) will re-awaken the ability of the system to produce audio. This was a suggestion from MOTU tech support, though there was no explanation as to why it works. The other %20 of the time I have to disable/re-enable core audio (try that, BTW) or restart to fix things.

 

So, I don't have an exact solution, but it might be worth toggling some of the settings of the Apogee control software to see if that will help.

hi I have investigated into this issue a little bit more

 

it seems that logic cannot play 32 bit files

 

now this seems bizzare. when i open my logic session it states that logic is now in 32bit mode?

 

I really do not understand

 

I have 32bit 48hz wavs and when I drop them into an blank logic template and I can see the stems but hear no audio

 

any advice?

[Eriksimon]

Logic officially doesn't support 32 bit files, but it should automatically convert them to 24 bit files.

If for some reason it doesn't (as seems to be the case) you should consider asking for 24 bit files to begin with.

The "switching" to 32 bit mode by Logic is not related to your audio file problem. It's a separate issue that just happens to happen simultaneously - imho.

thanks this has worked

 

I loaded the files into the session saved the session closed the session reopened the session and the wavs were automatically converted by logic

 

done

 

thanks
