Perfect for editing mono audio. But using the 45 degree angle cut on stereo=
 material produced a noticeable ping-pong effect at the splice, where one c=
hannel would transition slightly before the other. So the steeper angle cut=
 was added to the edit block to minimize that effect. Joel Tall, the invent=
or of the EdiTall blocks, said that he set that angle to give a good crossf=
ade with no ping-pong for stereo at 15 ips. This is more like a 10ms crossf=

Even with the crossfades created by the angled splices, clicks would someti=
mes be created at edit points. This was usually traced to using a magnetize=
d razor blade. Something I'm glad has been relegated to the dustbin of hist=
