/**
 * <h3>4.11.   Relative volume adjustment (2)</h3>
 * <p/>
 * <p>   This is a more subjective frame than the previous ones. It allows the<br>    user to say
 * how much he wants to increase/decrease the volume on each<br>    channel when the file is played. The
 * purpose is to be able to align<br>
 * <p/>
 *    all files to a reference volume, so that you don't have to change the<br>    volume
 * constantly. This frame may also be used to balance adjust the<br>    audio. The volume adjustment is
 * encoded as a fixed point decibel<br>    value, 16 bit signed integer representing (adjustment*512),
 * giving<br>    +/- 64 dB with a precision of 0.001953125 dB. E.g. +2 dB is stored as<br>
 * <p/>
 *    $04 00 and -2 dB is $FC 00. There may be more than one "RVA2" frame<br>    in each
 * tag, but only one with the same identification string.</p>
 * <p/>
 * <p>     <Header for 'Relative volume adjustment (2)', ID: "RVA2"><br>
 *     
 * <p/>
 * Identification          <text string> $00</p>
 * <p/>
 * <p>   The 'identification' string is used to identify the situation and/or<br>    device where
 * this adjustment should apply. The following is then<br>    repeated for every channel</p>
 * <p/>
 * <p>     Type of channel         $xx<br>
 *      Volume adjustment       $xx xx<br>     
 * Bits representing peak  $xx<br>
 * <p/>
 *      Peak volume             $xx (xx
 * ...)<br> </p>
 * <p/>
 * <p>   Type of channel:  $00  Other<br>                     
 * <p/>
 * $01  Master volume<br>                     
 * $02  Front right<br>                     
 * $03  Front left<br>
 * <p/>
 *                     
 * $04  Back right<br>                     
 * $05  Back left<br>                     
 * $06  Front centre<br>
 * <p/>
 *                     
 * $07  Back centre<br>                     
 * $08  Subwoofer</p>
 * <p/>
 * <p>   Bits representing peak can be any number between 0 and 255. 0 means<br>
 * <p/>
 *    that there is no peak volume field. The peak volume field is always<br>    padded to whole
 * bytes, setting the most significant bits to zero.<br> </p>
