The Haas effect is a very short delay that can be used to thicken a track. In this movie, I will show you how to set it up and let you listen to what it sounds like. The Haas Psychoacoustic theory states that a delay of 30ms or a less is not perceived as a distinct event. That means if a delay on the snare drum was set to 50ms, you would hear two separate events, the initial snare hit then the delay. If you set the delay to less than 30ms the two would blend together and you'd hear them both as a single event. Let's try that just so you can hear. Let's bring up our delay.
Let's set at the 50ms. This is our snare drum. Let's solo it, have a listen. (Music playing) Okay, let's mute the delay just so you can hear. (Music playing) So you can hear two distinct events happening: the snare hit then the delay shortly after. Now let's move this down to 30ms. Now listen to it.
(Music playing) It's a lot harder to hear the distinct events that are happening. If we move it down to 20ms and listen again. (Music playing) A short delay of less than 30ms can be used to thicken a sound that seems a bit thin.
It can be used to stereoise a mono track by panning the dry track to one side and the delay to the other. Let's have a listen to what that sounds like. Let's solo our guitar and have a listen to that. (Music playing) First thing we are going to do is we are going to put this at 50ms again, just so you can hear it. (Music playing) Now let's put it down to 30ms.
(Music playing) Really hard to hear the delay this time. And what we are going to do is pan that delay to the right-hand side because the Guitar is already panned to the left side. Now listen to the stereo effect that we get. (Music playing) Regardless of how you use it, the Haas effect is a very powerful and sometimes overlooked tool in your mixing toolbox.
It's a short delay of less than 40ms that can be used to thicken up a track or stereoize a mono track.
