    I'm using Airtime 2.2   There seems the be lacking punch and gain , when we go live with our software such as Sams Broadcaster at normal levels there is a huge difference in volume sound...

    What can be done about this  there seems to be no volume setting anywhere 
    I just need to boost it about 2 notches 

    thanks

    Please go into the library page of Airtime and enable the "ReplayGain" column. What are the values for the tracks that sound different?

    i've got the same problem. the volume seems equal beetween files, but it's low at the end (for example, on a windows 7 pc, playing using many software (wmp, winamp, foobar, etc...), peak never hit half of the bar. Settings seems great, i just don't find where to set the volume of output

    The fact is that the level at the output of all files receive the same, but too low. Apparently used ReplayGain, but the level in the settings hardcoded too low. Bring this option in the settings, or put hard to 0db.
    ----
    In russian:
    Дело в том что уровень на выходе у всех файлов получается одинаковым, но слишком низким. Видимо используется ReplayGain, но уровень в настройках жёстко прописан слишком низким. Выведите этот параметр в настройки, или пропишите жёстко до 0db.

    My files are file vary from -12.00 to -9.00  so the volume is at the same level at output of sound for all the files

    the problem is I need to bring the master volume up  its way to low I have the flash player or winamp pratically at MAX ! 

    I m connected output to Shoutcast server by the way

    Hmm, the ReplayGain algorithm thought your files were too loud and defn reduced the volume from the original (the files themselves were not touched) .

    Try this command and see if it helps:

    sudo -u postgres psql -c "update cc_files set replay_gain = 0" airtime

    You can change the files to be even louder if you wish (substitute 0 with 5 for example)

    thanks ! same question as Derek...
    And also, is it possible to do, for example ReplayGain = stored ReplayGain + 3 (for example)? Is yes, how?

    Thanks a lot

    Reply to @Derek:

    You will need to do this everytime. We will look into providing a volume slider that will allow you to change the Replay Gain offset as you wish.

    Reply to @Jerom+furious:

    Take a look here:


    If you are familiar with programming, $data is a simple array of media_items. Simply add something similar before the function returns $data:

    foreach ($data as $d) {
        $d['replay_gain'] = (string) ($d['replay_gain'] + 3);
    }
