Created attachment 285642 [details] Chrome/Safari Technology Preview 1) Load 1 chunk of my MP3 (I have 1 mp3 split in 5 chunks) 2) Decode the chunk with "decodeAudioData" 3) Now try to read .duration for this chunk a) On chrome 48.32 seconds b) On Firefox is 48.32 seconds b) On Safari Technology Preview is 268.70 seconds It look like Chrome/Firefox give me the chunk duration instead Safari is giving back the duration of entirely song (268 seconds is exactly the song duration for all chunks).

1) Open the link with Safari technology Preview http://jsfiddle.net/vynvu/201/ 2) Wait for "can play" alert 3) Click "play" 4) On Safary technology Preview you will got 277 seconds 5) On Chrome/Firefox you will get 10 seconds
