If your MP3 songs are too long, trim them with cutting tools.
MP3s are lightweight, compressed audio files found on many websites. If you have a library of MP3s, you may want to cut some of them. This allows you to create new variations of songs or remove segments you don't like. You can cut MP3 files to create short ringtones for your cell phone. A 3-minute ringtone won't work, but a 30-second one will. Several software makers offer tools that allow you to cut MP3 files quickly.
Instructions
1. Visit the Audacity website, and download the free audio editor (see Resources). This program is useful for editing and enhancing multiple audio tracks. You can also use it to cut an MP3. When you load an MP3 file into Audacity, the program creates a visible track in a horizontal graph. As you play the MP3, a time indicator ticks. This indicator shows you the current time location in the audio file. For example, after playing a song for 20 seconds, the time indicator will read "0:20." Use the indicator and the program's "Cut" tool to define new start and end points for your MP3. When you save the file, Audacity will save only the audio portion that you want to keep.
2. Navigate to the MP3 Cutter website, download Fast MP3 Cutter Joiner and install it (see Resources). Fast MP3 Cutter Joiner allows you to join and trim large MP3s up to ten gigabytes in size. Choose from multiple cutting options. For instance, if you want a file to be a certain length, enter that value in the "Length" text box. To set start and end points, enter those values in the corresponding text boxes. As you enter settings, Fast MP3 Cutter Joiner shows you how large the MP3 will be if you apply those settings. Use the handy "Fade" function to fade in the beginning of a song and fade out the ending. If you have multiple files to cut, use the "Batch Cut" function to trim them all at once.
3. Visit GoldWave's website to download GoldWave software (see Resources). Goldwave is a professional audio editing program with many advanced features. Digital music creators use it to enhance audio and mix multiple tracks. After importing an MP3, you can edit it using familiar "Cut," "Trim" and "Replace" commands. This gives you precise control over the final output. Using GoldWave's effects tools, you can also enhance an MP3 after cutting it. Add special effects, adjust tonal quality and even alter an MP3's pitch using GoldWave's audio effects controls.
