CD audio (question asked before melt down)
 

I have recorded some footage that I want to take the audio from and burn it onto a CD. Once I have burnt the audio and play it through my HiFi system, or computer, the sound is very 'tin' like. What is the problem?

What I have done:

Captured audio via the capture window in premiere (at 48000 hz), laid this down on the time line to trim and fade in and out.

Exported the audio via export audio (at 48000 hz) gave it a file name and then loaded it into windows media player in XP to create an audio CD. This goes ok and the CD is created.

Is there something which I have missed.

All the best,

Ed,
maybe you should have exported the audio file as a 44.1khz. I know that when you import cd audio into FCP or another NLE, you have to import it as a 48khz file. Cd's are 44 khz, so maybe the 48 khz audio file you burned will sound better if it's burned at 44khz.

I plan to burn a cd of some audio from some video I shot last night, some japanese style chanting and shamisen. I figured to import the audio into fcp, then export it out as a 44khz file and burn it onto a cd. If I get it to work okay, or if you get yours figured out, post the way you did it, I'll do the same, good luck.

The main question of course is, did it also sound tin like when
you played it originally?

Audio on a CD is indeed 44.1 kHz (that is 44100 hz). It is best
to convert this with some quality audio tool like Wavelab or
Cool Edit. These programs tend to have better audio resample
routines and other tools to fix audio related issues/problems.

Make sure your burn program doesn't have settings turned on
that "improve" (they rarely do so) the sound.

Cheers guys,

48000hz captured and exported audio sounds perfect when playing through the computer and from the original source.

What I have done so far to try and get around the problem:

Captured at 48000hz and exported at 44100hz - sound is even worse.

Captured at 48000hz and exported at 32000hz - sound is much better than at 44100hz but still does not sound as good as the original footage.

All of the above was done via Premiere 6. I guess the next thing to try is a specific audio program like Cool Edit or Wavelab as pointed out by Rob, to convert the audio.

I wouldn't have expected Premiere to do such a bad job. Try one
of these programs out. At least with Cool Edit you can download
a demo with which you can choose two working functions...
Pick save and the one you need to convert the audio sample rate.

That should leave you with a much clearer sound. I shall run
some test myself this weekend.
