Frequently asked questions

What is Extract Audio?

Pull the audio track out of a video as MP3, AAC or WAV.

When would I actually use this?

Trimming a clip to the part that matters, pulling the audio out of a video, and converting to the format a platform will actually accept.

What is the most common mistake?

Re-encoding when a copy would do. Every lossy pass loses quality that no later step recovers, so trimming without re-encoding is always the better route when the format is already right.

How is Extract Audio different from Audio Converter?

They sit next to each other but answer different questions: Audio Converter is the one to open when you need it to convert between MP3, WAV, M4A, OGG and FLAC, and change the sample rate or the channels. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Merge Audio is the closest one after this: Join several MP3, WAV, M4A, FLAC or OGG files end to end, and download the result as MP3, WAV, M4A, OGG or FLAC.

What else is worth having open alongside it?

Normalise audio loudness and Trim Audio — they come up in the same task often enough to be worth a second tab.

Where do the figures come from?

Processing runs in the browser through a WebAssembly build of the same encoders desktop tools use, on a single thread. That keeps the file private and off any server, and makes long clips slower than a native application.

How-toGetting the Audio Out of a Video Without a Second Generation of LossThe soundtrack inside your video has already been through a lossy encoder once. Whether extracting it costs you a second pass depends entirely on which of the three buttons you press — and "extract to MP3", the one everybody reaches for, is the one that costs.GuideCutting and Joining Audio Without a Click at the JoinThat tick at the edit point is not a flaw in the software. It is a step in the waveform, and a step is broadband energy — which is the definition of a click. Here is the arithmetic, measured, and the two places you can put a cut so it never happens.ExplainerPeak Normalisation Versus Loudness Normalisation, and the Target That Cannot Be ReachedScaling until the loudest sample hits a ceiling barely changes how loud something sounds. Measuring in LUFS does. This tool measures — in two passes, correctly — and then prints a result it never verified, which on ordinary material can be well over a decibel adrift.ExplainerMP3, WAV, FLAC: What Each Conversion Actually DestroysOne of these formats stores the samples, one stores the same samples packed smaller, and one stores a guess about what you would have heard. Which conversions between them are free, which are merely expensive, and which are one-way doors — with the arithmetic for each.How-toRemoving the Sound From a Video Without Touching the PictureOne ffmpeg command, no encoder, and a result whose video stream is byte-for-byte the one you started with — verified by checksum. Plus why the file barely shrinks, and the difference between a silent track and no track at all.ExplainerMOV to MP4: Why the iPhone Video Will Not Open on WindowsThe extension is almost never the real problem. A .mov and a .mp4 are cousins from the same family of file formats, and what actually stops the video is the codec sealed inside it — usually HEVC. Here is how to tell the two failures apart, and when changing the box is enough.
