Find in waveform / Find audio-silence Enables you to high speed scan for silent sections within an MP3 file. This is often useful if you have long MP3 files containing several songs with silence inbetween them. Note: This function have two different ways to operate, depending on if the current file is an MP3 file or not. Find in waveform (MP3 files only): This is the faster and more powerful search method. Press Cmd-F or choose Tools->Find in waveform from the menu. (When a file is added to MP3 Trimmer, this menu-option will be grayed out while MP3 Trimmer is building/refining the waveform data). You will be presented with a window like this: ![]() Select the desired function and press Search. MP3 Trimmer will immediately jump to the found location in the song. The waveform scan will always begin at the current location in the song, except when searching for the highest peak (the loudest part of the song). To make additional searching of the same kind (i.e find the second highest peak in the song) just press Cmd-G (Tools->Find again). Find audio silence (non-MP3 files): This is the old search method and is only used with non-MP3 files (files that don't contain the necessary waveform data). Since MP3 Trimmer knows when a file is an MP3 file or not, the selection between the two methods is done automatically. You have two sliders for customizing speed and sensitivity. You may have to try some different values to find an optimal setting. Scan speed: This slider determines how fast the scanning will be (up to 32x). On a slow computer, setting scan speed to fast may result in silent parts being missed. Sensitivity: This slider determines how sensitive the operation will be. A high sensitivity requires just a fraction of silence to trigger, while a low sensitivity need longer silence. Again, the speed of your computer may affect the result. In conclusion, these two sliders needs to be balanced together to find an optimized setting for your environment. The speed and sensitivity setting is remembered by MP3 Trimmer. When a silent part is found, the scan window will close and the locator in the main window will be positioned where silence was found. |
