Cut & Trim Your AAC Audio Online

AAC is mostly used in video, but because of its excellent sound quality at a much smaller file size, it's the go-to codec for most audio containers. Our tools allow you to trim your AAC audio, creating segments from lengthy recordings for podcasts, music, and mobile playback.

What Our AAC Trimmer Does

Refine AAC Output

Because AAC audio is often derived from video, some files come with unnecessary parts that aren't needed. With the help of our waveform, you can trim out those parts.

Handle AAC Frame Boundaries Correctly

When you use our tools to trim a full-length AAC audio file, no matter what you're trimming it for, we ensure the cuts are aligned with AAC frame boundaries to produce compatible and reliable output files.

Preserve MPEG-4 Metadata

We preserve the metadata stored within MPEG-4 containers whenever possible. So when you trim your AAC audio, you don't just get a shorter file, you also keep the important information that was part of the original file.

Support Both LC-AAC and HE-AAC

It doesn't matter which AAC audio you want to trim, our tools are compatible with the most common AAC profiles, including LC-AAC and HE-AAC. No matter which supported profile your file uses, we ensure you get the trimmed output you need.

Adjust AAC Volume

Not only do our online web app allow you to cut your AAC audio, but it also allows you to adjust the output volume, reducing loudness for audio that is too loud or increasing the volume for audio that is too quiet.

Keep AAC Quality

When you use our app to cut your AAC audio, we don't manipulate or alter the audio quality, so the resulting output remains the same as the original.
