Multiband Stereo Delay 
 
We saved the most interesting part of the stereo imaging module for last. Ozone offers a 
stereo delay control that allows you to offset the delay between the left and right channels. At 
first glance a delay might not sound that exciting, but a multiband delay can provide some 
very interesting stereo imaging effects. 
 
Of course you know that to make a sound come from the right you turn up the volume of the 
right channel. That’s true in the sense that sounds on the right side are louder in the right ear. 
But there’s another factor. A sound on the right reaches the right ear first. There is a short 
delay before it reaches the left ear. If you delay a channel by a few milliseconds you can 
effectively move sections of your mix around the stereo field. 
 
To experiment with stereo imaging using delays, slide the delay controls to the left or right. By 
default they’re grouped, so they all move together by the same amount. You should hear the 
mix adjust to left or right. 
 
If you’re mastering a live acoustic recording made with a pair of stereo mics, this can be an 
effective tool for adjusting the imaging without upsetting the balance (volume) of the two 
channels. If you’re mics were slightly off axis, it’s probably not the difference in volume that’s 
shifting the original mix to the left or right but the delay between the mics. 
 
That’s not the only creative use of the delay, though. Click on the checkbox labeled “Group all 
band delays” to ungroup the delays. Now you can offset the delay between the left and right 
channels for each band. Sliding a Delay slider to the right delays the right channel while 
sliding to the left delays the left channel. 
 
 
 
If you’re expecting to hear an “echo” you’re not hearing what you expected. These are very 
short delay ranges, from 0 to 30 msec. In this range of time you don’t perceive two distinct 
signals delayed in time as much as you hear a shifting of the image. 
 
So what can you do with a multiband delay? Try shifting the positioning of the bass using the 
Delay in Band 1. You can move the perceived position of the low end without panning. Or, try 
offsetting Band 3 to the right, and Band 4 to the left for a widening effect of the upper 
frequencies. There are a lot of creative possibilities here. Experiment. 
 
General Multiband Stereo Imaging Tips 
 
• 
You can generally do more widening of higher bands. 
 
• 
You may even want to do “negative widening” of lower bands to pull bass and other 
instruments to the center. 
 
• 
Monitoring on headphones is going to give you a false impression of the imaging of 
your mix. You really need to check imaging on speakers. Headphones will always 
“wider” because none of the right channel is being heard in the left ear or vice versa. 
 
• 
Try positioning lower frequencies with multiband delay as opposed to panning.
