Thread: how to apply replay gain while converting mp3 speech files to opus

    Re: how to apply replay gain while converting mp3 speech files to opus

    How to obtain same volume while listening to the converted opus file in android phone with headphones.

    I want to get same volume throughout the file I mean I don't want ups and downs while listening to opus file. Is there any DSP to achieve this.

    Suppose while listening to original mp3 source file at point A I got 90 % of maximum volume of my headphones and at point B I got 50% percent of maximum volume of my headphones and at point C I got 95 % of maximum volume. I want to convert to convert this mp3 file to opus file and if I listen this opus file in android phone with headphones I must get say 80 % of maximum volume of my headphones I mean there must be no ups and downs say 90 % at point A, 50 % of maximum volume at point B, 95 % of maximum volume at point C.

    Choose the 'Adaptive' option on the Volume Normalize DSP Effect.

    Under volume normalize I found two options starting with adaptive they're
    Adaptive ( EBU R128 )
    Adaptive ( Peak to Peak )

    Under the above both options I found the following entries

    Window Length ____ ms
    Desired Volume ____db
    Maximum Amplification x ___
    Info: Non-Live Dsp Effect

    I can't understand the above settings. I want to maintain same volume say 85 db through out the file for all files and so please suggest how to do so I mean which options to select and their values.

    Leave everything on default settings and choose 'Adaptive EBU R128'
