5 Awesome Tools for Audio & Video Editing

As someone who teaches pronunciation on a regular basis and prefers to do it with authentic materials, I have to edit tons of audio and video files. So here’s my selection of the best tools you can use for editing audio and video.

AUDIO

1. Audio Cutter

There are many online tools similar to this one, but mp3-cut.net is my ultimate favourite. It allows to trim your audio as precisely as possible by adjusting the start and end time manually. Pay attention to the last number: it’s deciseconds, guys, and it’s amazing. You can also fade in or fade out your audio. Finally, you can change the speed, volume and pitch of the audio. For more advanced users, there’s an equalizer function, too.

2. Audio Joiner

This tool is provided by the same platform as the previous one and has similar functionality. Before joining the audio files, you can trim them if necessary as well as fade in / out or crossfade them. Another good thing is that you can choose the format for your output audio file.

If you need more format choices, you can use this audio joiner tool instead but keep in mind that it doesn’t have the trimming function.

3. Voice Recorder

There’re various options available here. I know many teachers use Vocaroo, and it’s a good one with basic functions like retry recording, remove background noise and auto-adjust volume.

This voice recorder has a nice add-on: you can trim your recording if, for example, there’s a long pause at the beginning.

However, if you want to have some fun, go for this one. It allows you to modify your voice to sound like a man (if you’re a woman), a robot, or even a space squirrel.

VIDEO

4. Video Trimmer

If you already have a video and need to trim it, this is the best tool you can find. The functionality is impressive (for a basic user, of course): manual input for start and end time; rotation, speed and volume change; and other functions like cropping and looping your video.

Another great way to use this tool is when you do decoding practice with your students. By adjusting start and end time, you can play and re-play precise bits for your students to listen to be it just one word or a whole phrase (I found it wat easier to use than Aegisub).

5. Add Subtitles to Your Video

Now, this is something I’ve discovered recently, and it’s a real gem. Before, I used to add subtitles manually using a .txt file and time coding (to get precise timings, I was using Tool #4). I then reformatted the .txt file into the .srt one and added it to the video using a corresponding function in the video player. However, this tool allows you to do this much faster. It’s pretty intuitive: you type the phrases in the boxes on the right and then adjust the timing for each box at the bottom. Easy-peasy!

That’s it. I hope this info helps! These tools have made my lesson preparation easier and I can’t see why they can’t do the same for you 🙂
