Yes. Upload an MP4, MOV, MKV or other video and the converter pulls its soundtrack out and saves it as a lossless WAV, ready for your editor.

Standard uncompressed PCM at CD quality, 16-bit 44.1 kHz stereo, which every audio editor and CD-burning tool accepts without further conversion.

Not pointless, but understand it won't improve quality. It gives you an uncompressed working copy that prevents further loss while you edit, which is its real purpose.

WAV is uncompressed, around 10 MB per stereo minute. That size is the cost of being lossless and instantly editable. Export to MP3 or M4A for a small shareable file.

M4A is the MPEG-4 file container; AAC is the codec inside it that does the actual compression. In everyday use the terms are interchangeable when talking about audio.

Yes. Upload a video and the converter extracts its soundtrack and encodes it as M4A, giving you an efficient audio file ideal for Apple devices.

AAC generally sounds better than MP3 at the same bitrate and produces smaller files, making M4A a strong choice on Apple and modern Bluetooth devices.

Most modern hardware supports AAC, but some older car stereos and basic players don't. For guaranteed universal playback, convert to MP3 instead.

MP4, MOV, MKV, AVI, WebM, M4V, FLV and WMV. The converter reads the audio track from each and saves it as an MP3.

192 kbps, which is transparent for speech and fine for most music. Note the video's original audio quality is the real upper limit on the result.

Yes. Use the convert-to-WAV tool to extract the soundtrack as lossless PCM, which is the better choice if you plan to edit the audio.
