ToneBoosters Morphit is an AUv3 plugin for headphones correction and simulation and removes any unwanted coloration from your headphones! Enable accurate monitoring and calibration, mix with studio reference equalization, and improve the accuracy of your headphones. Used and trusted by thousands of studios worldwide, and now available on your mobile device! The ToneBoosters Morphit app captures the microphone (or external sound card) input and processes the signals in real time. To use it as a plug-in, use an AUv3-compatible host app such as Steinberg Cubasis, Apple Garageband, Audio Evolution Mobile Studio, Auria, AUM, or others. ToneBoosters Morphit will appear in the list of Audio Unit extensions for effect plug-ins. How to use Morphit as AUv3 plugin for headphones correction: 1. Connect your headphones to your iOS device (using the headphones jack, using BlueTooth, or using an adapter as supplied by Apple). You can use any of the many supported headphones listed here: www.toneboosters.com/tb_morphit_v1.html 2. Start your favourite AUv3 host app (Steinberg Cubasis, Apple Garageband, Audio Evolution Mobile Studio, Auria, AUM, or others) and add TB Morphit as Audio Unit insert effect to a track or output bus. See below on how to use Audio Units in various host apps. 3. Select the headphones you are using from the list of supported headphones provided within the TB Morphit app. That's it - all audio going through the Audio Unit plugin is optimised for your headphones. Key features: - The same professional sound as the acclaimed desktop version - Hundreds of headphones supported! - Unique feature: allow morphing of the amount of correction from 0 to 200% - Unique feature: allow simulation of any of the supported headphones and see how your mix translates - Unique feature: personalize the headphones target curve - Unique feature: use Harman calibration / target curves - Unique feature: data/measurement visualization mode - No external hardware required; works with any of the supported headphones models - Undo/redo, and A/B comparison - Color themes for the user interface - Max screen support in Garageband - Optimised for iPad and compatible with iPhone and iPod Touch See if your headphones are supported: www.toneboosters.com/tb_morhpit_v1.html What you should know: - Licenses acquired for this platform are not compatible with other platforms. - Audio Unit (AUv3) extensions require an iPad mini 2, iPad 4 or later models.
Noise Gate & Downward Expander
This audio effect plugin offers a more natural-sounding noise gate for music production. It uses downward expansion to smoothly reduce gain, avoiding abrupt volume changes and unwanted fluttering. Achieve clearer audio without listeners noticing the effect.
- Downward expansion for natural sound
- Smooth gain reduction
- Prevents abrupt volume changes
- Reduces background noise
- Minimizes gate fluttering
- Clearer audio quality

WHAT DOES THIS PLUGIN DO THAT OTHER NOISE GATES DON'T? Most of the iOS recording apps already come with a built-in noise gate effect. So why do you buy another noise gate? There are 2 main reasons: clearer sound and more natural gate-closing sound. 1 - DOWNWARD EXPANSION SOUNDS MORE NATURAL THAN OPEN & SHUT GATING The simplest noise gate plugins simply set the volume to zero when the input level drops below a threshold. The abrupt change in volume from that process sounds unnatural and makes it obvious that you are using a noise gate plugin on the signal. Instead of using a gate that fluctuates between two states (open, closed), this plugin uses downward expansion to gently and smoothly reduce the gain as the input drops below the threshold setting. An example to illustrate this: With the downward expansion ratio set at 2:1 and the threshold at -10 dB, when the signal drops below the -10 dB threshold level, the plugin doubles its distance from the threshold. So a signal that comes in 2 dB below the threshold goes out 4 dB below; 10 dB below the threshold comes out 20 dB below, and so on. The big advantage to this method is that when the signal is just slightly below the threshold, say 1/2 dB for example, it won't be reduced all the way down to zero volume, so you don't hear an abrupt change as the signal drops below the threshold. Instead it just seems that the quiet sounds are even quieter, and they decay faster than they normally would. This allows you do eliminate a lot of background noise without the listener knowing that you are using a noise gate. 2 - SMOOTHER FILTERING IN THE ENVELOPE FOLLOWER MEANS LESS DISTORTION The key challenge that all noise gate designs struggle to overcome is how to make sure the gate doesn't flutter open and closed several times at the end of a sound. This is a serious challenge because the input signal is a wave, meaning that it is constantly moving up and down and it crosses above and below the threshold with every up and down motion. How to keep the gate from opening and closing in time with the oscillation of the sound waves? There are many ways to do it, but the basic idea is to slow the gate down somehow, so it can't open and shut too quickly. Of course, slowing the gate down or delaying its closing is not desirable because we need it to close as quickly as possible when the input signal ends and open immediately when it starts up again. Each noise gate plugin handles this problem in a different way, and therefore each one has its own unique sound. To hear how a noise gate performs in this respect, set its release very fast, pluck a low guitar string (or hit a bass note on the piano) and let ring out, listening as the note decays down to the threshold level and the gate starts to activate. If your noise gate allows a fast enough release time, you'll hear a buzzing noise as the gate rapidly flip-flops open and closed for a few moments before settling in the closed position. The audibility of the buzzing sound as the gate closes determines the quality of the plugin. Any gate can avoid buzzing if its release time is set very long, but only the best of them can close down quickly and smoothly without buzzing. This noise gate plugin has a unique smoothing filter to ensure that the gate makes as little noise as possible when opening and closing, while still being able to open and close very quickly. 3 - SIDECHAIN HIGH-CUT AND LOW-CUT FILTERS ALLOW YOU TO GATE OUT PART OF THE SIGNAL WHILE KEEPING OTHER PARTS The side chain input is the signal that the plugin follows to measure the input volume. If you have bass drum bleeding into your hi-hat mic, you can gate out the bass by cutting bass frequencies out of the side chain. The result is that the gate only opens when the hi frequencies from the hi-hat are sounding, not when the bass drum is bleeding through.
