    PS26U - Audio compression - Ratio

    Hi,

    I need to work compression on an audio on the PS26U.

    The Ratio setting is normally (2:1 ; 4:1 ; etc). On the PS26U this adjustment appears in numbers from 1 to 100.

    Does anyone know how I would adjust a 2:1 compression with these numbers. Would it be 2 or 50?

    Thanks.

    Hello,

    Where do you see these 1 to 100 numbers ?

    Sorry, I misunderstood your request. I thought you were talking about CODEC level of compression.

    Curious as to why you want to compress the audio.... what are you trying to achieve?

    Reduce the dynamic range between low and high level.

    After equalizing, apply general gain and cut through the pre-established threshold, the excess that I don't want to appear in the audio.

    Considering that it was an event recorded on S-VHS in 2005, and previously edited and rendered in 2008, I considered the result to be very good.

     
    In addition to equalizing, increasing the mid-high, high frequencies, increasing the gain and compressing the excess from -1dB, I also applied a low cut at 40Hz.

     
    Improving concert sound is never theoretical, and lacks experience in it, especially when it comes to excessively live loud heavy metal sound.

     
    Follow the link of the video where I changed the audio.

    Have you tried Normalize?

    The audio of this show was born with a problem.

    The main camera sound came from the mixer console, and the support camera sound came from the microphone itself.

    However, the console sound burst into the main camera.

    For this reason, in editing, the sounds of the two cameras were mixed, and what prevailed most was the support camera, leaving the main camera at a very low volume, just to compose the general volume.

    In my attempt to improve the sound, I decided to use the PS26U's audio features.

    First I equalized, boosting high mids and highs, and cutting frequencies below 40Hz, as I didn't care to hear it. It was more noise than sound.

    Then I opened the compressor, in order to raise the overall gain, limit a threshold of around -1dB and apply a moderate ratio.

    That's when I realized that the ratio adjustment wasn't how I'm used to seeing it (2:1 ; 4:1 ; 8:1 ; etc), but with numbers from 1 to 100. That's when I decided to ask on the Forum, to see if anyone would know what a 2:1 ratio would be.

    I ended up setting number 2.

    Considering the sound I had before, I thought the result was good.

    It's already been done, but if anyone knows how to elucidate the PS26U's audio compressor ratio, I'd appreciate it.

    Hug.

    In the last few decades, all the music we hear, in the studio mastering phase, goes through a compressor.
