[Xiph-Advocacy] example of lossless fade out

[Jose Ramirez]

Hello again,

The feature of taking a lossy file and editing it with fades without
degrading quality is an important one.

Here is a file from:
http://pan.zipcon.net/
http://dsl-63-249-19-10.zipcon.net/mp3/chamber_orchestra/OCT-08/  

In this piece there is 38 seconds of perfect music IMO. This example was
cut out. 
The beginning sounds fine but the end doesn't, the abrupt ending makes
it unusable.

Having the feature of lossless fading, the cut off can be ended smoothly
without losing quality.

If the copyright license allows 'everything is recyclable' with lossless
cutting and fading.

The big question is, it possible to edit fade ins and outs in vorbis and
theora without re-encoding. If for some technical reason it's not, then
the fade feature should be added to the HTML 5 spec.

HTML 5 could take a page out of SMIL, SMIL 2 had fade in and out for
visual media, SMIL 3 added it for audio:

To get to the point were there are millions webpages with xiph media,
the process needs to be easy.
