Mozilla Developer Center s HTML5 media guide describes an event for audio and video elements called "loadedmetadata". Is there anyway to get the metadata for files? I am writing an HTML5 extension for Google Chrome and I don t know what the metadata for the audio files I m creating a player for beforehand.

According to this you can use filereader.readAsBinaryString(file); to get the binary data of the ID3 tag.
filereader.readAsBinaryString(file); will asynchronously return a binary string with each byte represented by an integer in the range [0..255]. This is useful for binary manipulations of a file’s data, for example to look for ID3 tags in an MP3 file, or to look for EXIF data in a JPEG image.
