Can I edit MP3 files online?

How do I merge two MP3 files together?
Simply upload both MP3 files to your Flixier library and drag them onto the editing timeline. You can arrange them in any order, add a crossfade effect for a smooth transition between them, and then export the merged track as a single MP3 file.
Can I remove background noise from my audio?
Yes. Our AI Audio Enhancer tool allows you to remove background noise, enhance speech clarity, and fix volume levels with a single click. This is perfect for cleaning up recordings made in noisy environments or with low-quality microphones.
Can I add music or sound effects to my MP3 files?
Yes, with Flixier's online MP3 editor, you can easily add background music, sound effects, or voiceovers to your existing MP3 files. Simply import the additional audio tracks and arrange them on the timeline to create a richer audio experience.
How do I extract audio from a video?
Import any video file into the Flixier editor. Right-click the clip on the timeline and select "Detach Audio." This will separate the audio into its own track, which you can then edit independently or export directly as a high-quality MP3 file.
