每次教會有活動時，常常會有很多mp3音樂，但幾乎每個節目使用的音樂音量大小都不一樣，這對控音很麻煩。控制不好，表演一開始的音樂不是太小聲，就是太大聲（容易嚇到人...呵呵），大家可以用這個軟體，先將所有音樂做各調整，這樣活動時只要按需要，微調混音器（mixer）就可以囉！

Tired of reaching for your volume knob every time your mp3 player changes to a new song?
MP3Gain analyzes and adjusts mp3 files so that they have the same volume.

MP3Gain does not just do peak normalization, as many normalizers do. Instead, it does some statistical analysis to determine how loud the file actually sounds to the human ear.
Also, the changes MP3Gain makes are completely lossless. There is no quality lost in the change because the program adjusts the mp3 file directly, without decoding and re-encoding.

備註：如果妳是要燒成cd的話，nero有個選項（平衡所有歌曲的音量），將其勾起。這樣也是一種方法。
