hi

i don't know but i have audition cc 2018 & 2015 and when i import a file i miss always the fade out icon

i fix it only creating a multi track with sample rate 48000

now my question , i work mostly with flac files (mostly @صفحتي علي ادوبي.1  ripped from cd ) and other audio like mp3 or mp4 (many of them have a sample rate of 44.1)

when i drag my 44.1 audio on the multi track with sample rate 48000 i got this warning

now my question  ?

outside mp3 or mp4 lossy format , but i work with flac too , when i Mixdown section to a new file or export multitrack   @ 44.1 (because i have to burn )

1)

do I commit a big mistake i term of degraded audio ?

2)

working with flac audio @صفحتي علي ادوبي.1 import to a multitrack session with sample rate @48000 and after re-sample at 44.1 , do I lose audio quality ,audio frequency ?

thanks

sorry for my poor english

Audition's sample rate conversion is the best there is - that's been independently verified some years ago. That said, if you are going to do sample rate conversions, you really should, however it works out, only do them once. So if you have a flac file at 48k and you want to put it in a 44.1k session, then ideally you do the sample rate conversion first. But it doesn't actually matter if you let it happen automatically in a multitrack session - it's only doing what you would have done anyway. The only difference is that it uses automated settings, rather than letting you choose them.

So if you want to burn the results to a CD, then have the session as a 44.1k one. If you need the result for anything else as a 48k file, then sample-rate convert the final mixdown file back, as you'll be sample-rate converting your actual mix, which is presumably what you need.

The inherent quality loss in MP3 or MP4 files is way greater than any loss you get in sample-rate conversion.

    Hi SteveG

    only do them once

    i read it

    so start a multitrack @48k and drag @48k and 44.1k files  and after converting to 44.1k is a mistake

    seeing as i drag 44.1k in a multitrak @48k there is first resample and converting again to 44.1 it's the second resample

    right?

    but if i have to work with @48k and @44.1k together is the only solution isn't it?

    about the sample rate (it's just a curiosity about audition) is audition dipendent by the external audio card or internal audio card?

    i mean if the audio card (just an example) doesn't support 96000 , i create new single audio from  @96000 will audion show it avaible and play the audio or will not show in the option the 96000 sample rate ?

    thanks SteveG

    The safest thing to do if you have to work with two sample rates is to have two versions of all the source files - one at 44,1k and the other at 48k. That way you only ever have to convert each file once!

    Sample rate conversion has nothing whatsoever to do with your sound device - it's a purely computational process. Whether your sound device can play the resulting file is another matter altogether, and completely unrelated.
