What would the hash be for?</blockquote><br>
To avoid string duplication and to provide an easy lookup mechanism. My
background is in digital broadcast so I tend to be rather mean about
bits.<br><br>
<blockquote type=cite class=cite cite="">If you mean to avoid string
duplication, I think just duplicating the text <br>
would be easier to implement and easier to spec. In terms of sizes,
the text <br>
"Rolling Stones" including null termination is 15 bytes.
A two second, 96 <br>
kb/s, 22050 kHz, mono mp3 is going to take around 5000 bytes.
Saving 7 bytes <br>
by using an 8 byte hash instead probably wouldn't be worth it, plus it'd
make <br>
the files harder to read with a hex editor. :-)</blockquote><br>
If string duplication and lookup are not issues then the solution can be
very simple.<br><br>
The next question which comes to mind is do need a new frame type or can
we use the "GEOB" frame in some way?<br><br>
