Not sure which test tones your talking about, the V2 ones (which are the only accurate test tones to use, not counting the officail CBS ones) are not mp3:
Owen,
Tone sequence is:
Centre Front - Right Front – Centre Right – Rear Right – Centre Rear – Left Rear – Centre Left – Left Front – Centre Front
5 seconds of each. The tones are phase & amplitude correct, produced digitally. If your decode does not work as intended, it is not this set of test tones !

The matrix nature of SQ makes it impossible to do a proper job, .
Thanks for the SQ test tones, I have downloaded them. I'm aware that a standard SQ decode provides only 3db front to back seperation. I'm OK with that.
If you can suggest something which does the job as a easily as SQDecode but gets the decode right then I'll happily use it. I'm even prepared to spend money. What I'm not prepared to do is a complex sequence of steps (which can easily be done wrong) as appears to be needed with Adobe Audition.
It turns out a Queen 1973 BBC broadcast "1973.09.13 London, Golders Green Hippodrome" was SQ encoded. .
Are there any official decodes of these available so I can see if my decodes are producing the same results? [...].
Here you go!

The two samples were created with the SQplus script
These will be totally inacurate i'm afraid (i wrote SQplus so i know).

It's recently been discovered that this early Queen radio broadcast was SQ encoded. I've run one track through SQDecode and made a short DVD Audio and it does decode quite nicely.
