Exporting audio stream in Premier 6.0 sounds like %#@! tips?

howdy,

So, I've got a high quality 46 meg .WAV file source as the music piece in my Premier project. Sounds wonderful when playing out of Premier. The dump to DV tape sounds awesome as well.

However, when exporting the audio stream OUT of premier (at 48000, with or without compression, no interleave), the audio sounds like ass when it gets loud.

I've dumped the audio gain down to as low as 50%, but then I just get quiet sounding ass.

Any pointers would be much appreciated.

(I can't just MUX the source .WAV as there are time gaps and a nameplate .WAV in there as well)

cheers,

Do you have a sample of what it sounds like?
And are you letting premiere doing the 44100Hz->48000Hz conversion or is your audio already 48000Hz to begin with?

thanks for taking the time to respond.

Here's a clip of the good original source:
http://fuzzygeek.com/files/evanescence-good.wav (1.9meg)

Here's a clip exported by premier:
http://fuzzygeek.com/files/evanescence-ass.wav (2.0meg)

the original source was a MP3 encoded at 320kbps, 44100Hz stereo.

I've tried importing/exporting at both 48000 and 44100, and the export always sounds like crap.

I tried using the normalizing feature in dBpowerAmp when converting from .MP3 to .WAV, and the .WAV has all this distortion as well.

Appreciate the help!

cheers,

Well this is sodding odd. Now the clip from the "good" souce sounds all corrupted as well.

I'm pretty positive that the problem has to do with the high levels in the audio. I just have no idea how to fix/normalize them.

Gah!

T_T . . they sound like they are the sasme file to me !!!
must be your sound card.

yes, the top one is 44k - very loud but fairly clear.
the bottom one is 48k - same . . .
I do not hear the differance between them!

it must be your sound card.

The full "good" sample is 42 megs, so I can't post that. That file sounds great.

I imported the good .WAV into an audio editor and cut out a bit and saved it ... and voila -- crap sound.

(soundcard is a SB live; tried it on a couple different computers and a couple different speakers, so I'm pretty sure it's not my speakers that are blown out).

Besides, if it was my sound card, why would it sound like crap on your computer?

thanks,

I'm not using a Sound Blaster ^^
. my audio card can handle 44k, 48k, 64k, 72k and 96k stereo wav's upto 8 channels;
. . which is why I am saying that, "it must be that your sound card is out-of-date.

T_T

8) ok . . think of it this way; no matter how you try to beef-up a 4 cylinder engine in a pick-up, it will never pull the same weight as a V8 if the same Truck-Body 8)

have you ever tryed to use any of the YMF-724 lines of Yamaha sound cards ? - they are designed for 48k wav's, your sound-blaster is not

I'm sorry, I still don't understand how the sound card would affect the actual quality of the .WAV file being processed.

Even if the SBLive card (or any of the other cards -- none of which were Yamahas (built in Dell blech)) couldn't handle 48k .WAVs (whether or not it can I'm not sure) -- that doesn't explain why one .WAV file would play and sound just fine ... but as soon as I try to edit or export or manipulate the .WAV file, it starts sounding like crap.

In theory, I should be able to put the .WAV file on a computer with no sound card, use audio editing software to manipulate it (it's not the sound card that's processing the .WAV, it's the software, isn't it?), take it off that machine and put it on a sound-enabled machine and play back the .WAV.

For example -- for the "good" clip I linked above, all I did was take the "good" .WAV I have, put it into a sound editing program, chop out 10 seconds of it and save it under another filename. Since we're working with digital files, if all I do is crop out a bunch of bits, it should continue to play back the same bits as the good file, shouldn't it? Instead the clip /also/ starts to sound like ass.

Or am I completely wrong and it's actually the sound card that processes the bits of a .WAV file?

I haven't used any of the Yamaha sound cards. I've always been under the impression that SB was pretty much 'industry standard'... I'm not heavy into audio engineering (which is probably why I'm having so many problems

)

Ah well.

Thanks,

or it could be as simple as finding the newest drivers for your sound card ^^

I "have" run into problems with mis-matched drivers on different operating systems

if sound blaster is truly up-to-date then they should have the drivers available at their web site ^^ - right ?

Nyaaaaarggggh.

I think you're right -- it was the sound card. I just ran a 41000-41000 import/export on my home machine (which has the sblive card) and it's clear as a bell.

I could have /sworn/ it distorted on my home machine as well, but I'd been doing a lot of the editing on the machine in my office.

*sigh*.

thanks for your time.
