What is Audio Trimming?

Audio trimming is the process of removing unnecessary or unwanted parts from an audio file.

This can be done for many reasons such as reducing the size of the file, removing unwanted sections, removing background noise, etc. 

Whatever may be the reason, the whole process is quite simple and easy to follow.

Best Software to Trim Audio

Well, now that you have learned what precisely audio trimming is and where it's mostly used, you might be wondering what some of the best tools available are.

There are many audio trimmers that can perform quite efficiently. However, not all of them are free, and some even require the installation of extra plugins and add-ons to make them fully functional.

AudioDirector is one of the few solutions that act like a swiss army knife, with all the tools you need ready to go.

Let's take a closer look at both the online and offline versions of AudioDirector and see how they can fulfill your needs.

AudioDirector Online - Best Web-Based Tool

AudioDirector Online

AudioDirector Online is a web-based application that requires no installation whatsoever. You only need an internet connection and an up-to-date web browser such as Chrome, Safari, Firefox, etc.

The best thing about this tool is that it doesn't leave any footprint on your computer or require an installation. Once you open the website, you will be presented with a user-friendly interface allowing you to complete all your sound editing tasks.

You simply upload your audio, remove unwanted parts by trimming the audio track, and then download it in your desired format. The online audio editor provides multiple tasks such as audio trimming, vocal removal, voice changing, etc. 

The only drawback of this tool is the file limit. You can't upload a file that exceeds 100 MB in size or has a duration of more than 10 minutes. 

But that doesn't mean it isn't a good choice as an audio trimmer. It is the best option to trim a short audio or music track.

How to Use Software to Trim Audio

Just like we mentioned before, some people are not very comfortable when it comes to using online tools. Perhaps this is because they want complete freedom of file size and supported formats.

Another thing is that the offline software versions are independent of the internet connection speed. This is another advantage because no matter how choppy or laggy your connection gets, you can still cut audio files without any problems.

Now that we have talked about the advantages of using an offline tool, it's time to learn how you can actually use it to trim your audio files.

Download and install AudioDirector onto your computer and follow the steps below.

Step 1: Import Your Audio File

AudioDirector Interface - Import

Just like the online counterpart of the software, the first thing you need to do to begin the process is to bring your audio files into the program. Open AudioDirector and simply drag your desired audio file into the software window and drop it, automatically importing it.

You can also use the Import media button to search for and upload your file. 

As mentioned earlier, there is no limit when it comes to file size. The file formats that are supported by AudioDirector are quite vast, including MP3, WAV, FLAC, M4A, and a wide range of video formats.

Step 2: Trim Unwanted Portion

Once your file has been successfully imported, you are ready to trim. You can start trimming the audio by highlighting the portion you want to trim with mark-in and mark-out.To do this, drag the yellow markers on the timeline.

We highly recommend playing the video or audio file first before making any trims to confirm your markers are in the right place.

To trim, you need to open the Adjustment drop-down and the Trim Audio option. There you will find two options that allow you to either Remove selected part or Keep selected part. You can also adjust your marks via timecode. 

When you are ready, you can Apply your trim.

Another option is to use the Cut tool to remove your highlighted selection. Or use the Crop tool to remove the unselected area. 

Step 3: Export Your Edited File
