Convert 12 bit audio to 16 bit after recording has taken place

We were recording a presentation last week off a Sony HDV camera. The camera was sending 12 bit audio for the first half of the recording. When the .cmproj file is opened in Camtasia 1.2.3 for Mac the audio waveform crushed. If I apply a dynamic filter and boost the the master gain up to 150% I can hear there is audio. However, at that point the hiss and noise are very overwhelming.

Is there any way to salvage the audio? It was recorded on a Macbook Pro running 10.6.8 and I have full access to Adobe CC if anyone knows of a trick in Audition or Premiere.

Thanks for any help.

Best Regards,
Eric

Hi Eric,

It's very difficult to salvage problematic audio after it's been recorded. The badness is "baked in" and it's incredibly difficult to extract great audio when it's recorded incorrectly. Even professionals with Pro Tools systems would have problems with this issue. Sorry! File it under "live, learn and do it differently next time!" :-)

But keep looking out there! Perhaps someone more qualified in audio troubleshooting can assist!

Best,
David
