Co to jest Audio Metadata?

Audio metadata is structured information of audiobooks, metadata typically included des fields such as title, author, narrator, publisher, genre, language, and cover art. This data is stored in thee file 's headder (e.g., ID3 tags for MP3 files or Ftags for WAV files) and s read by by digital storefts, media, and library managements.

Metadata can be dividd intro two considerations: technel metadata (np., file format, bitrate, sampe rate, duration) and descriptive metadata (np., title, author, genre, senopsis). For ACX submissions, both type matter. Technical metadata ensures that te file meets the platform 's technical requirements, while descriptiva metadata enhancances searchality andd user experience. Without close metadata, even a perfectly narrate d audiook can be mislabeled, overloked, or rejected during quality accorance.

ACX akceptuje audio files in MP3 format (constant bitrate 192 kbps, 44100 Hz samplerate rate, 16- bit) and WAV format (16- bit, 44100 Hz). The file 's metadata mutt be embedded correctly prior toupload. Tools like Audacity, iTunes, and specialized tag Editors (e.g., MP3Tag, Kid3) allow you tu populate these fields before conversion.
