Just importing you material does not change anything in the data. When you open the audio in SB or AU, how does the waveform look? Oversteered? If so, your mic or recording level was too hot and there is not much to be done about the clipping.
What you are hearing may be caused by clipping reduction schemes (AGL) in the camera or player.
But it sounds fine on camera when plugging my headphone jack from the cam into my $5000 audio setup, it sounds fine.
It also sounds fine playing back on my computer in the utility program my Sony cam came with.
Also, by change the AVCHD format to .mpg (to make it somewhat readable), I was able to extract the audio from the video file straight into my audio program (it has a import audio from video feature) it worked just fine.
The problem only occurs when importing audio embedded with the AVCHD video straight into adobe premiere.
I'm going to test loading in a mp3 and compressed video with audio such as .mov or mpg and see what happens.
I was able to extract the audio from the video file straight into my audio program (it has a import audio from video feature) it worked just fine.
At this stage, I would just Save_As PCM/WAV 48KHz 16-bit, and then Import that into PrPro, to replace the muxed Audio from the AVCHD file.
I just imported a wmv windows 7 sample video. Played back fine.
Loaded in a windows 7 sample mp3. played fine.
Played it back in VCL, fine.
That is way to much trouble.
I'm baffled. Tried export, re imported in PP... same prob.
Is everyone as stumped as me? How do I contact Adobe about this? Maybe it's a bug?
Got it! How did I not see think of this before!
Tried a different format on the Sony HXR-NX5U, Dolby Stereo. And it works.
What I was using before as a LPCM (L for Linear, it's a lossless codec) Codec format which I gues premiere does not like.
Adobe Premiere would probable recognize PCM because it is Non Linear Quantized and older format and it explains why LPCM was distorting - becuase it's on a wider linear scale that exceeds what Premiere supports - it was still seing the PCM part of the code but not that it was Linear.
The audio nerd prevails.
Huh, well I don't see PCM nor LPCM in supported audio formats.
Interesting, and thank you for posting your findings. I would not have anticipated that LPCM/WAV would be an issue, but here it seems to have been.
As for supported formats, look for WAV, and then there should be some annotations on PCM and possibly LPCM.
Glad that you got it handled, and that you have reported, so that others can learn from your experience.
