Question

32 bit float wave forms from Zoom f6 still looked clipped after lowering gain

So I just started using ghe Zoom f6 to record audio. I had a bit of the audio file that recored past 0db. when I put the clip on the timeline and lowered the gain, it no longer sounds clipped, but the wave forms look clipped. Howver if I take the clip into Audition and lower the gain, the waveform reduces respectfully to the changes made. both clips sound the same, which is what is most important, but it makes me nervous that I am doing something  wrong within premiere.

 

I have attached a picture of the clip in a premiere timeline, the top clip has been reduced by 18db in Audition via dynamic link the bottom was reduced by 18db in premiere.

 

just wondering if it matters that the wave form still looks clipped?

 

Thanks!

    Hi everyone, 

    I'm discovering your issue as I have the same. Hard to find any solution on the web (but glad not to be the only one).
    I suppose I'll lower the gain in Audition en Import the file in PP. Not a perfect solution since it makes the wordflow heavier, but it helps to work with proper visual waveform for cutting.

    I'll let you if I find a better solution !

     

    PP 24.0.0 / 32 bits audio from Rode Wireless Pro.

    Ok I found a way to "solution" the graphics : 

    1) On the clipped/not-really-clipped section > right click > Audio Gain > Normalized max to 0 (I don't know the english label since I'm french)

    2) Then, still on clipped/not-really-clipped section > right click > render and replace.

     

    Pros : The true waveform will display.

    Cons : It creates a new wav file in the project. NB : it may implies other drowbacks I'm not aware of.

      Thanks Nick,

      Yeah I have learned to live with it at this point, I mostly use my F6 for dialogue and live event recording so seeing peeks and needing to edit to the audio is not really required but it's nice to know there is a work around.

      Today Adobe sent me an email asking me to mark which response on this subject was the correct answer to my problem. Well for all who might stumble upon this, no I have not found an answer to the problem.

       

      Mr. Haugen has been helpful in adding to the conversation and clarifying the issue, but no actual answer or "fix" to why the wave forms do not respond correctly has been discovered. I assume as Mr. Haugen suggested maybe PP is just not capable of eading the 32 bit float waveforms as Audition is.

       

      Again the sound of the audio is fixed correctly when I lower the gain in  premiere, but the audio waveforms are not responding correctly the way they do in Audition.

       

      If Adobe support would like to jump in ...would love to hear from them!

      same clip of 32 bit audio, the top had the gainlwered by 18db in Audition, the bottom had the gain lowered by 18db in PP.

        I'm still assuming the Premiere audio software simply doesn't work to display dorectly from the 32-bit float audio audio files. And may or may not for some time. Not all that helpful, but you aren't getting any more. They don't ever discuss what might be coming in a future release.

        Thanks Neil,

        I figured as much, it was kinda just a jab at them because of their email asking if someone else had helped me in the forum.

        I am happy that it decodes it correctly and I get the desired control of the actual audio file, even without the propper waveform. As of now FCP still cannot decode it properly so I guess thats a win for Adobe useres. As anyone who has edited accross multiple NLE in their career can attest to, no one NLE is perfect, and for me PP is the best even with it's wierd glitches and bugs.

         

        Thanks again for walking through it with me.

          You might close the project, dump all your cache files, and relaunch Premiere. That might just be the cached waveform showing there, rather than the 'current' one.

            thank you so much for  giving me a hand with this...I emptied cache and once all peak files were recreated still the same thing....so I put another instance on the timeline and lowered gain again and still the same thing with the waveforms...

             

            odd!

            So where you're at, is that in Premiere, the sound is clean but the waveforms aren't, but in Audition the sound and the waveforms clean up together. Well, not particularly optimal, that!

             

            I wonder if there's some other cache ... pek files or whatnot, that didn't get dumped that needs to.
