Whilst creating a higher-order-ambisonic encoder in SuperCollider I was getting really strange effects ... volume blow outs and the like. Then I realised that I was moving a point across a 4 km length in 10 seconds ...

:)

To move 4km in around 10 seconds, you have to be moving slightly faster than the speed of sound .... hence the 'sonic boomish' effects I was getting. I tweaked the distance to try and get it as close to the speed of sound as possible ...and WAMO.. kaBOOM!

Note: there are 2 passes here. The first (left to right) is not fast enough to get a sonic boom. The second pass is done at close to the speed of sound ... and so has some very strange effects.
