How do the features and functions compare to SMAART? Looks to be very similar, but are there added benefits to this software? The Autotune feature and being able to create FIR filters looks interesting, but I wonder about file format compatibility on that...

 

The main focus is different and you need a different workflow to use it since its not real time like Smaart.
For “live” tuning, Smaart is better.
I would use RiTA if I didnt have a lot of time to tune, so I would take the sweeps and tune the system offline. I could spend all the time I want playing with x-over slopes, delays, all pass, etc, then just load the values to my dsp.
Other use case would be lets say that you measure a system, email the files, I tune it offline and send you the values to input into your DSP.
Or do a tune with Smaart and then measure with RiTA for the last 5% offline.
The FIR’s can be exported in txt, csv or wav. I haven’t tried to see if they are compatible with my Open DRC, but will try it in the next few days and report back.

It also seems to work pretty good to make target curves including the phase.

It seems to import the FIR files no problem.
Ill measure it later today and report back.

I recently found out about RiTA and decided to try it out.
Its an FFT analyzer made by a Spanish engineer called Pepe Ferrer and its team at Global Audio Solutions Global Audio Solutions
The software costs 210 Euros, but I paid 336 Euros for the software and the 5 day online operator course.
So after a 15 hour live training via Zoom by the creator and playing a bit with the software to measure my monitors and car, here are my thoughts.
It's an FFT analyzer like the ones we use with some key differences.

1. It was designed to measure with the least noise possible. So instead of using pink noise (which it can also use) it uses an ESS (Exponential Sine Sweep) to capture the Impulse Response (Instead of the TF like the others). The advantages of doing it this way where explained in the course, but to sum it up the IR can be manipulated and since all systems are linear an non time variant you can optimize the measurement with its DSP. It also makes it easier to see the sub IR, which can be hard on other analyzers.
2. It has an 8 channel virtual DSP. This is one is a highlight for sure. After you take the IR, you can use the DSP to apply gain, polarity, delay, X-overs, EQ, all pass filters, it can average or sum several measurements and you can capture the result as both a new IR or a snapshot.
3. The virtual DSP is also a great learning and teaching tool in which you can play with several signals to learn about phase, summation, etc.
4. It has automations to auto align mains to subs, subs to subs. It tells you what to do to fix it. Add x amount of delay, add all pass, polarity, etc.
5. It can auto EQ to target, magnitude, phase or both and generate FIR filters.
6. Its still in development, so a lot more interesting stuff should be added.

Conclusions.
It's a great tool with its pros and cons, like all of them.
Like the rest of the tools we use to tune, it's not specifically designed for car audio. We are using pro/home audio tools for the car. The only tool made for the car is TuN/MAX and you pay the price to play, but it's the easiest one to use in real time in the car.
I'll be using RiTA a lot more in the future but still use Smaart as my main tool.
Here are some pics.

RiTA FFT Analyzer offers precise measurements using ESS for Impulse Responses, minimal noise, and an 8-channel virtual DSP. It's useful for pro/home audio but not car-specific. For real-time car audio, TuN/MAX is easier. RiTA is promising but still developing. Before placing an order, I explored About CanadianWritings.com to understand more about their team and values. The detailed information about their writers' expertise and the company's mission to provide quality academic assistance convinced me to give them a try. Their commitment to maintaining high standards is clear, and it gave me peace of mind knowing my work was in good hands

Thanks helps a lot for a beginner like me.

 

Been playing a bit more with RiTA.
Here's a cool party trick.
Lets say you already have a lot of measurements done with Smaart.
You just export them as ASCII.

Import them into RiTA as an external TF/IR.

If you click the SUM button down on the right, it will give you the summed response of all the selected measurements shown in white.

If you select the auto align function on the dip it gives you several options.

You have LF, HF and Subwoofer.
LF is to align mains to subs.
HF aligns mains to fills (front fills, rear fills, side fills, etc)
Subwoofer gives you options for gradient, end fire, etc.
It obviously made for pro audio, but in this case, LF works just fine for mid bass to sub optimization.

And after you click on it it gives you at least one option, sometimes two to get it right.

And finally you see the new summed response.

First in car measurements with RiTA.
So far, I really like how it works, but its more like a confirmation tool that a live tuning one, since it measures with sweeps and not a real time measurement.
I measured each speaker, full side, full system, etc.
The cool part is that you can play with the data after with the dsp to optimize it and then input the parameters into your dsp.

 

RiTA looks like it has similar functionality to Smaart Data Modeler?

 

Yes, that part is similar.
RiTA has more options for filters and auto aligning either phase, eq to target, FiR filter creation.
It’s also way cheaper.
RiTA doesn feel as finished or polished as Smaart, but the developers do mention that it’s a product in development and that early adopters will all subsequent version free, after paying current price of course.
For example, they just released Little RiTA. It’s a real time dual channel FFT, like Smaart to measure in real time and sent it free for all RiTA users.

How accurate have you found the auto phase alignment and eq when input into the DSP?

 

The auto align works great. It can align mains to subs, mains to mains, subs to subs. It gives you delay, polarity and APF to apply if needed to get speakers to sum properly.
The Auto EQ and Phase (can be done individually or together) creates FIR filters to be uploaded into pro audio dsps. Might be able to upload it to something like the MiniDSP Open DRC, but sold mine so cant try it.
