## What is Stereo Lag Time?

This is an audio unit plugin that puts a small delay between the left and right channels.

Why would you want to do that? Here's why:

We recently saw a video interview of a very famous guitarist in which his guitar was delayed a few milliseconds in the right channel. It may have been caused by unusual microphone placement, or perhaps it was just an error on the part of the person who recorded the video. Whatever the reason for it, it sounded great. He was playing into a vintage amp with no other reverb or delay, but the sound had a wide stereo image that didn't sound electronic or artificial and didn't distort the natural sound of the amp. This is commonly known as Haas effect.

With most delay effects it's not so easy to get a precise, very small delay on just one channel, but this app does it with just one simple control. 

In case you need to modulate the effect, this plugin smoothly transitions between different delay time settings, causing a pitch shift while the delay time is on the move toward its new setting.

This plugin is simple, so we are giving it away for free. Enjoy!

Tres bon, c’est facile et immédiat.
Bravo

### 4/5 — Good and free

*2022-06-28*

Works great for me and definitely beats spending 5 bucks on a single effect

### 5/5 — Minor and Simple but Very Effective

*2020-12-12*

All it does is delay one side of a stereo track - but you’d be surprised how deep and developed this can make your otherwise flat-sounding tracks seem. Really glad I got this and am using it as needed. All it takes is a very slight delay for a major difference.

### 5/5 — Issues ☹️

*2020-11-17*

Hello!

I love this plugin! But recently I’ve had issues with it. Every time I reopen the project (garageband for ios), the stereo lag plugin goes to off (like a reset) on every track I put it in. How can I fix it? I’m really sad cause I use this a lot, and my projects don’t sound the same after this problem happened.

Hope you guys can help me!

Thanks!

### 4/5 — Great plugin, but not saving settings

*2020-11-17*

This plugin is great. However, when I close my project and come back later, the plugin settings are always restored (to zero). So I have to redo it everytime. Have you experienced the same issue? If yes, what is the fix?

### 5/5 — This is crazygoodddd but

*2020-10-13*

Hi, I'm writing this, but when I turn off the Garage Band and come back to the project after working with this effect in the Garage Band, all plugin settings are initialized or turned off. I don't know if this is a problem that can't be fixed is only for my iPhone Garage Band!!!! If you can fix it, please fix it plz

### 5/5 — Wonderful App. Does as it says and makes great sounds sliding left or right

*2020-08-13*

It puts a delay between channels. At a slight adjustment it makes everything instantly wider. More? It is so strong as a utility it makes cool sounds...
