What is Bitmapping?

Well, is that improving it or what? Which option is better?Fuxion

Bitmapping has nothing to do with audio.

Basically bitmapping takes a picture and places it on the face of a polygon. So if you had a cube in 3D and wanted to make it dice, you could paste a picture of the difference faces of the dice on each side of the cube.

Bitmapping is a set of routines which filter the audio to enchance parts of the audio such as making softer parts louder so they can be heard more clearly. As with all fancy things, this could result in a slow down in games so use wisely.teebeenz

Actually, while Bitmapping is more commonly known as a graphics term, it is also used in the field of audio enhancement. Hence the bitmapping feature in the voice settings for the PS3. So you're both right.

So what does the Bit mapping in the PS3 option menu do? What does it change, graphics or audio?

I've yet to experiment with these features, as I trust the recording on the CD itself to be faithfully imported into the PS3 using MP3 @ 320kbps. This link can help you: http://manuals.playstation.net/document/en/ps3/current/settings/bitmapping.html

Audio bitmapping is related to the form of filtering used when producing the audio source (CD/DVD/other). Typically, in the realm of cd's, the audio source has to be converted to 16 bit and some form of down-sampling has to be used. Different systems use different types of downsampling. Unfortunately, I don't know what the ps3 'types' actually refer to - but I am led to believe that Type 2 refers to 'noise shaping' and Type 1 refers to 'Dithering' - which are both certainly forms of downsampling.

Essentially, when downsampling, there are inevitable compromises made in the process, and the bitmapping methods can help to minimize these issues.

I honestly can't tell you what is best to use - as with all things audio, it's best to have a try and listen and see what you prefer. It is alleged by many that the 'average' listener will struggle to hear a difference. I find that WAV audio playback of ripped CD's is best with no bitmapping at all, but that could easily be personal preference!

As for Type 3, the only information that I can find is that this is 'enhanced bitmapping', which may relate to Sony's SBM (super bit mapping) technologies that they make use of - namely in SACD recordings. Don't hold me to that though.

A little info on SACD and SBM can be found here:http://www.daisy-laser.com/technology/techsacd/techsacd13.htm

Hope that helps.
