Choose from 18 audio exports. MP3, AAC, M4A, WMA, AC3, EAC3 and MP2 offer 128, 192 or 320 kbps. Videos are converted to audio, not to another video format.
Start the batch, then download each result or all audio files in a ZIP. Keep this tab open. An invalid file does not block the remaining files.
MP4 belongs to the MPEG-4 Part 14 family. Possible audio codecs, depending on the file: AAC, MP3, ALAC. If several audio tracks are present, only the first is exported in stereo. Other tracks and video are ignored. A filename extension does not guarantee compatibility: the engine checks the codec and actual duration. Silent, protected, damaged or incompatible files are rejected. No remote links or DRM bypass.
Conversion runs in your browser. Your file is not uploaded to MyBeatz, published or added to a library. The engine downloads on first use, which can take a moment. No account or MyBeatz credits are required.
Exports are stereo at 44.1 kHz. PCM and lossless formats use 16 bits; OGG, MKA and WebM use Vorbis quality 5. ALAC is saved as .m4a, unlike AAC M4A. Only the first audio track is retained, without video, tags, chapters or artwork. Keep your original.
