Talk:Au file format

What does au stand for or why did they pick just au?

[edit] .au headerless or no headers file conversion format

Wikipedia and other internet sources indicate that when converting to .au, headers are always created. Is there any software that will convert audio to .au without headers? Thanks! WhatLasts 16:43, 20 September 2006 (UTC)WhatLasts

The AU format is a audio container file format, hence the entire extent of the format is the header. Removing the header would mean that you just have a raw stream of whatever was in the file (e.g. PCM, u-Law, A-Law, ADPCM data). Hence it is somewhat nonsensical to talk about a AU file with no headers - it is just a raw data file then. --Ozhiker 09:11, 13 February 2007 (UTC)

Nope. Old-style *.au files have no header. They are 8-bit mono µ-law sampled at 8000 Hz. (the NeXT used them too, as did others, often with a slightly faster sample rate in the 8000 to 8192 range) They can be send directly to /dev/audio. When interpreted as a new-style *.au file, you may hear a bit of noise at the beginning since the header gets played as audio. 24.110.145.202 20:19, 14 October 2007 (UTC)
