Do you have a large MP3 music collection that you either downloaded off the Internet or ripped from CD? ´ç½ÅÀÌ Å« MP3 À½¾Ç Ä÷º¼Ç Áß Çϳª¸¦ ÀÎÅͳݿ¡¼ ´Ù¿î·Îµå ¶Ç´Â CD¿¡¼ »©³½ ÀÖÀ¸¼¼¿ä? If you do, you probably noticed that many songs are recorded at different bitrates and are either really loud or really low compared to a normal MP3 recording.

This is very annoying because if you are listening to a random selection of music, you have to constantly adjust your speakers either up or down because of the variation in sound level between the MP3 files. ¸¸¾à ´ç½ÅÀÌ µè°íÀÖ´Â À½¾ÇÀ» ¹«ÀÛÀ§·Î ¼±Á¤Çϱ⠶§¹®¿¡, ´ç½Åµµ ²÷ÀÓ¾øÀÌ ¼Ò¸® ¼öÁØÀÇ À§³ª ¾Æ·¡¿¡ÀÖ´Â MP3 ÆÄÀÏ °£ÀÇ ÆíÂ÷·Î ÀÎÇØ »ç¿ëÀÚÀÇ ½ºÇÇÄ¿¸¦ Á¶Á¤ÇØ¾ß ÇÒÀÌ ¸Å¿ì ¼º°¡½ÅÀÔ´Ï´Ù. So can anything do done? ±×·¡¼ ¾Æ¹« Áþµµ ÇÒ ¼ö ÀÖ½À´Ï±î?
MP3Gain MP3Gain is a great freeware program that will analyze and adjust a collection of MP3 files so that they all have the same volume! ±× ºÐ¼®ÇÏ°í ±×·¡¼ ±×µéÀº ¸ðµÎ µ¿ÀÏÇÑ º¼·ýÀÌ MP3 ÆÄÀÏÀÇ ¸ðÀ½À» Á¶Á¤ÇÒ ÈǸ¢ÇÑ ÇÁ¸®¿þ¾î ÇÁ·Î±×·¥ÀÔ´Ï´Ù! This is one of my favorite freeware programs because I can now listen to all my music without worrying about one song blowing out my speakers. ¶§¹®¿¡ Áö±ÝÀº ¸ðµÎ ³» À½¾ÇÀ» ÇÑ °î ¹Û¿¡ ºÒ°í ³» ½ºÇÇÄ¿¿¡ ´ëÇÑ °ÆÁ¤¾øÀ̵éÀ» ¼öÀÖ½À´Ï´Ù À̰ÍÀº ³»°¡ °¡Àå ÁÁ¾ÆÇÏ´Â ÇÁ¸®¿þ¾î ÇÁ·Î±×·¥ Áß ÇϳªÀÔ´Ï´Ù.
Note that MP3Gain can adjust how loud each song sounds without any quality loss. ±×°Ô ¾ó¸¶³ª Å« ¼Ò¸®·Î ³ë·¡¸¦ Á¶Á¤ÇÒ ¼öÀÖ½À´Ï´Ù MP3Gain ¾î¶°ÇÑ Ç°Áú ¼Õ½Ç¾øÀÌ µé¸°´Ù. The program has two modes, Track and Album. ÀÌ ÇÁ·Î±×·¥Àº µÎ °¡Áö ¸ðµå, Æ®·¢ ¹× ¾Ù¹üÀÌ´Ù. Track mode will correct the volume on a group of unrelated songs to a particular target volume that you specify. ÃßÀû ¸ðµå´Â ƯÁ¤ ´ë»ó º¼·ýÀ» ÁöÁ¤ÇÒ ¼ö¾ø´Â ±× ³ë·¡ÀÇ º¼·ý ±×·ì¿¡ ¿Ã¹Ù¸¥ °ÍÀÔ´Ï´Ù. It corrects each song individually. °³º°ÀûÀ¸·Î °¢ ³ë·¡¸¦ ÇØ°áÇÕ´Ï´Ù.
Album mode corrects a collections of related songs (like a group of songs on a CD album) relative to other collections of songs. ¾Ù¹ü ¸ðµå´Â CD ¾Ù¹ü¿¡¼ ³ë·¡ÀÇ ±×·ì () ³ë·¡ÀÇ ´Ù¸¥ ¸ðÀ½¿¡ »ó´ëÀûÀ¸·Î °°Àº °ü·Ã ³ë·¡ÀÇ Ä÷º¼ÇÀ» ÇØ°áÇÕ´Ï´Ù. Applying the Album gain is like adjusting the volume knob once for each CD you play in your CD player. ¾Ù¹ü À̵æ Çѹø ½ÅûÇÏ¸é °¢ CD¸¦ CD Ç÷¹À̾¼ Àç»ýÀ»À§ÇÑ º¼·ý ³ëºê¸¦ Á¶Á¤ÇÏ´Â °Í°ú °°´Ù. The overall volume of the album is adjusted, but the volume difference between songs in the album are preserved. ¾Ù¹üÀÇ ÀüüÀûÀÎ º¼·ý Á¶Á¤µÇ°í ÀÖÁö¸¸ ¾Ù¹ü¿¡ ³ë·¡ »çÀÌÀÇ º¼·ý Â÷À̰¡ º¸Á¸µË´Ï´Ù.
If you are a music lover, this probably all makes sense, otherwise it may not. ¸¸¾à ´ç½ÅÀÌ À½¾ÇÀ» ¾ÖÈ£ÇÏ´Â ¸ðµçÀ̰¡, ±×·¸Áö ¾ÊÀ¸¸é ¸»ÀÌ ¾øÀ»Áöµµ ¸ô¶ó¿ä. Either way, if you have lots of albums in your collection, then use Album gain, otherwise just use Track gain if there are lots of unrelated songs in your MP3 collection. ¾î´À ÂÊÀ̵ç, ¸¸¾à ´ç½ÅÀÌ Ä÷º¼Ç¿¡ ´ÙÀ½°ú ¹«°üÇÑ °æ¿ì¿¡´Â ±ÍÇÏÀÇ MP3 À½¾ÇÀ» ¸¹ÀÌ »ç¿ëÇÏ¿© Ä÷º¼Ç¿¡ÀÖ´Â ´Ù¸¥ ´ÜÁö ÀÌµæ ¾Ù¹ü Æ®·¢ Æ÷ÀÎÆ®¸¦ »ç¿ëÇÏ¿© ¾Ù¹üÀÇ ¸¹±¸¿ä.
To get started, add some files or folders where all of your MP3 files are located. ½ÃÀÛÇÏ·Á¸é, ¾î¶² ÆÄÀÏÀ̳ª Æú´õ¸¦ ¾îµð¿¡ ±ÍÇÏÀÇ ¸ðµç MP3 ÆÄÀÏÀÇ À§Ä¡¸¦ Ãß°¡ÇÕ´Ï´Ù.
Once all the files are in the list box, you need to let MP3Gain analyze them so that it can determine how to adjust the files.

From the Analysis menu, you can choose Track Analysis, Album Analysis, or Max No-Clip Analysis. ºÐ¼® ¸Þ´º¿¡¼ ÃßÀû ºÐ¼®, ¾Ù¹ü ºÐ¼®, ¶Ç´Â ¸Æ½º ¾Æ´Ï - Ŭ¸³ ºÐ¼®À» ¼±ÅÃÇÒ ¼öÀÖ½À´Ï´Ù. Track and Album analysis are like what we talked about before, either a single file or a group of files. Æ®·¢°ú ¾Ù¹üÀ» ºÐ¼®Çϱâ Àü¿¡ ¿ì¸®°¡ ¹«¾ùÀ» ¾ê±âó·³, ÇϳªÀÇ ÆÄÀÏÀ̳ª ÆÄÀÏÀÇ ±×·ìÀÔ´Ï´Ù.
The program will give you some basic information about the files, such as the volume, track gain, and more. ÀÌ ÇÁ·Î±×·¥Àº º¼·ý, Æ®·¢ °ÔÀΰú °°Àº ÆÄÀÏ¿¡ ´ëÇÑ ¸î °¡Áö ±âº» Á¤º¸¸¦, ±×¸®°í ´õÁÖ´Â °ÍÀÌ´Ù.
Finally, once the analysis is complete, you can adjust the actual volume (gain) of all the MP3 files. ¸¶Áö¸·À¸·Î, ÀÏ´Ü ºÐ¼®ÀÌ ¿Ï·áµÇ¸é, ´ç½ÅÀº ½ÇÁ¦ º¼·ý¿¡ÀÖ´Â ¸ðµç MP3 ÆÄÀÏÀÇ (°ÔÀÎ)À» Á¶Á¤ÇÒ ¼öÀÖ½À´Ï´Ù. Again, you can choose from Album gain or Track gain. ¶Ç, ´ç½ÅÀº ¾Ù¹ü¿¡¼ ¾òÀ» À̵æÀ̳ª Æ®·¢À» ¼±ÅÃÇÒ ¼öÀÖ½À´Ï´Ù.
