Product Details

True Audio TrueRTA Audio Spectrum Analyzer Software

True Audio’s Level Two (1/3 per octave) TrueRTA™ is a real-time software-based audio instrument for testing and evaluating audio systems using a PC with basic sound capability. TrueRTA™ also includes a digital voltmeter that reads true rms voltage and dBu levels, and an audio spectrum analyzer. To set up your own audio test lab you will need a digital voltmeter to calibrate TrueRTA™ for your sound card and a collection of cables and adapters for connecting electronic gear to your sound card for testing. Most sound card jacks are 1/8 inch. If you want to do acoustic testing of loudspeakers in addition to the above you will need a calibrated microphone (True Audio recommends the Dayton Audio EMM-6), a microphone preamplifier or mixer, an audio power amplifier to drive the speaker under test, and cables to connect the line-out of the sound card to the input of the audio power amp. Software can be upgraded to Level Three (1/6th octave) or Level Four (1/24th octave). Minimum System Requirements: 500MHz Pentium III processor and 64MB of RAM

True Audio TrueRTA Audio Spectrum Analyzer Software
True Audio TrueRTA Audio Spectrum Analyzer Software is rated 4.375 out of 5 by 8.
Rated 5 out of 5 by from Essential ToolThis is an essential tool for anyone concerned with frequency response of loudspeakers, especially with respect to room balance, graphic equalization, etc. It only make sense to buy the inexpensive, full 1/24 octave version that lets you take a sweep from 20-20khz and smooth it to 1/3 octave. That way you can compare room response graphs of R and L speakers both on the screen at once and set the balance both by eye and ear so you can go to sleep happy with your handiwork.I use this delightful and necessary tool to experiment like crazy without going insane.

Rated 5 out of 5 by from Wonderful value for the tech who knows how to use it.I've used many hardware and software analysis tools over my 40+ years as a tech, engineer, environmental noise consultant, and teacher. Most, i.e. SMAART, are very expensive, especially for a retired guy on a fixed income. This is such a wonderful tool. Perfect for my current projects. Hat's off to John Murphy, and PE for making this widely available.

Rated 4 out of 5 by from Functional software you need, works well, interface is datedI was so excited to get this and use it with the Dayton condenser mic (also purchased here) to test out a new subwoofer and its placement in my home theater. You'll need the mic, a usb mic interface, and this software, and for about 1/3 the price of a basic component RTA, you have a professional tool.This software works, and most likely has worked for a long time based on the dusty interface. . . small buttons, no mouse over/contextual help, etc. I hate having to resort to the manual for software nowadays since you can typically learn while using the product. But the manual is well written, informative, and helps with the sea of tiny buttons. Even if it was written in the Pentium 4 days.Interface aside, it allows you to calibrate and compensate for all of your hardware as well, down to the output voltage and inherent frequency response curve of your sound card, and in simple easy steps.So, what my experience tells me is that they haven't changed anything because it just works. So overall, maybe that isn't that bad.

Rated 4 out of 5 by from Great - Averages Multiple Measurements for a Room!This software gave me the ability to take multiple measurements throughout a room. I wanted to be able to average these multiple measurements and this software will do that. I can finally get the average system response for an entire room. The upgraded software at 1/24th octave resolution is awesome for seeing how standing waves, peaks, dips, etc. change throughout a room. It is great to be able to have the Pre-EQ and Post-EQ averaged responses just a click away from each other. That way I know how accurate my attempted improvements were. A picture is worth a thousand words when showing a customer what they are hearing throughout an entire room (1/12th octave resolution is my favorite for this. Sometimes I find that different locations in the same room will have completely opposite bass responses graphs.) I've decided EQ'ing an entire system based on one measurement is not wise (especially below 200 hz. I use this software to see the response of a system at the mix position and compare it to what the audience will hear. I've used this while designing speakers, testing the frequency response of an EQ or Microphone Preamp as well as generate test tones at any frequency I want. The sound system calibration is a great feature that allows you to know your computer is not adding its own color to your measurements. I like that it has shortcuts for the commands I use most. It is not a flashy program, but it gets the job done. I have not used other software that allows users to average multiple measurements, but I've not seen another for $40. I have upgraded to level 4 and love it. I've been using this software for 3-4 years.I'm sorry Mac only Users will not be able to use this software unless that has changed recently.

Rated 4 out of 5 by from Works great, easy to use, glad I bought it.Only complaint is the cost to upgrade from 1/3 octave to higher frequency resolution levels (1/6 octave, etc.) The minor added complexity in the code does not justify the high surcharge. I would upgrade for a small service charge, but not for double the original price.

True Audio TrueRTA Audio Spectrum Analyzer Software

I'm looking at purchasing this for testing loudspeakers in their listening room-listening room measurement what have you. What other items should I purchase along with this-i.e one box solution-mics cables stands, etc-already have a recent laptop. Thanks!

Asked by: Mojo
I would recommend a Dayton UMM6 (390-808) with this as the measurement mic

How do I copy onto my new computer-I lost the original disc

I really enjoy this product. The Real Time Analyzer software's oscilloscope feature is a bonus as well as it's spectrum analyzer capability. My problem is that I just got a new computer and I want to transfer the program from my old laptop to my new laptop. Any help would be appreciated. Thanks
Asked by: Charlie G.
I think you will need PE tech help for this. It isn't copying, it is also installation.

Mic calibration

I would like to know if this software uses the mic calibration files for Dayton EMM-6 mics to compensate for FR errors? I could not find anything on this on the True Audio website or FAQs, execpt for a comment that if the individual mic is not calibrated, then don't use a file at all. This makes no sense to me.

Plug all into ypur tape in/out on your receiver, then plug-in 'aux' your Computer, go to you-boob, and listen to some Black Rebel Motorcycle Club 100- 110 videos, and you'll ge the sound you want.... Make sure your mic. is a dual....You probably have a 'hum', not "dead-silent", and THAT will misconstrue A LOT of things in this sense. Try a Power Module w/ an isolator, or turn-off ALL fans as well as flourescent lighting, and even 'dimmers'.... I've had to do ALL of that o get the 'hum' out of the system as is...

How does the True Audio RTA compair to the Dayton Omni Mic system.

This question was asked before and the True Audio RTA was compaired to the Goldline RTA not the Omni mic.
Asked by: Kelly383
The TrueRTA system has been around for a number of years, and is a good product. While there are some differences in the features, I'd say a few of the primary benefits of the OmniMic system would be the overall simplicity, convenience, and portability. Everything you need (aside from a laptop or netbook computer) is included; you can open the box, load up the software, plug in the USB microphone, and have the OmniMic system up and running within 10 minutes. As far as head-to-head comparison of features, I'll leave that to other users, or you can refer to the manuals for each product.
