Multiband Haas Effect vs deriva tape machine

Haas effect is a micro-delay applied to either the left or right channel of audio (but not both). This simple effect creates a realistic and natural-sounding increase in the width of the stereo field that still sounds good when mixed back to mono. It is the most simple and effective way to take a mono input and make it sound like stereo. But Haas effect has some problems. First, it can create phase cancellation problems in the bass frequencies, causing them to loose volume. Second, it can sound a bit artificial at high frequencies. This multi-band Haas effect plugin is a simple way to get the stereo width you need in the midrange frequencies without loosing the impact of the bass or making the treble sound phasey. You select any number from one to four bands, each with its own separate Haas delay setting and adjustable crossover frequencies. This makes mono audio sound wide and spacious while preserving the original tone and spectrum transparently.

deriva is a tape machine plugin that is meant to give a polished and warm silky sound on your mix or master bus. built on published research papers¹ and my own experience recording with analog tape in studio, the sound is true to how real tape actually sounds. although the engine under the hood is advanced and complex, the controls are meant to be simple and easy, so you can set and forget and focus on your music. a fun feature is that you can pull the tape while the audio is running, causing the pitch to go up or down. the controls are pretty much self-explanatory: input and drive control how hard the signal and saturation will be. also sounds great on drums! bias simulates everything from a badly aligned machine to a brand new and serviced one, together with wear. a common misconception is that there is a lot of wow and flutter on tape machines. most professional tape machines do not have much flutter and wow, but in deriva you can push the machine a bit if you like - now with separate controls. tape speed affects the sound of the tape, where the lowest is dark and the highest is studio clean. if you want to bring back some of the high frequencies lost in tape speed, you may use the tone knob next to it. if you're bored with the UI you also have the possibility to change the colors and invert them. ON THE IPAD deriva is an Audio Unit (AUv3) and works with Logic Pro, GarageBand, AUM, Cubasis, Loopy Pro, Drambo and the rest. the standalone version either works as a live effect for your instrument, but also as a tape machine player: load in your own song and listen to it "on tape". you may also record live, or export the whole song with your current settings. Requires iPadOS 15 or later. also available for Mac, Windows and Linux at eikremaudio.com. ¹ Jatin Chowdhury, "Real-Time Physical Modelling for Analog Tape Machines", Proc.
