Soundcard must have line in and line-out connections. Most modern soundcards will work just fine, for example almost any Soundblaster (Live, Audigy, Aydigy2 etc.) is fine. Computer/laptop equipped with a decent soundcard.Ī 500 MHz Pentium III class PC with 64MB RAM running The program itself is very small (~1.4MB installed), but the project files are around 10MB each, so make sure you have atleast that much of free space on that drive. Here is a little proof why 1/24 is recommended.īefore anything, read the help files/topics, they are very helpful. If you absolutely can't make it, take level 3, it comes with 1/6 octave resolution. Level 4 retails $99.95, but it's all worth it.

I definitely recommend level 4, because this way you get the full 1/24 octave resolution, which is almost a MUST, especially if you are planning to some EQ'ing with BFD or similar.
Truerta a weighting upgrade#
True Audio offers four different upgrade levels from 1 to 4. To make the most of it, you need to purchase an upgrade. Unfortunately the demo is quite limited so you can't really use it efficiently. The free demo of the program can be downloaded from here. TrueRTA is a nice and small RTA-program (Real Time Analyzer) made by John Murphy. If the sound is weak, with only high frequencies, then pin 3 needs to be tied to pin 1 (ground).Since HTSpot transferred this quide into section where you have to be a paid member to get in, I decided to copy it here. If they don't then the safest is to leave pin 3 (jack ring) floating, and if that works, then great.
Truerta a weighting how to#
In many cases, the manual will tell you how to unbalance the output.
In summary, it's impossible to know what's the right way unless you know what sort of output you have. If the output isn't differential, just impedance balanced, then shorting pin 3 (jack ring) to ground should be fine assuming the sensible case that it's pin 2 that actually carries the signal.
Usually each opamp has a series resistor to protect the output against just such an occurrence, but that raises the output impedance from essentially zero ohms to 75-100 ohms so sometimes isn't done. with an opamp on each leg, then it's not OK as one leg will be shorted to ground. If the output is just plain electronically balanced, i.e. not ground referenced, so shorting pin 3 (jack ring) to ground is fine. If the output is electronically servoed, then it's effectively 'fully floating' i.e. However, most outputs these days are not transformer balanced, but use electronics. Pin 3 needs to be left unconnected in this case. If centre-tapped transformer balanced that's not fine at all as half the transformer gets shorted out. If fully floating transformer balanced, that perfectly fine. Unbalancing a balanced differential output by shorting XLR pin3 (jack ring) to ground is fine or not, depending on the type of balanced output. This is the connection that isn't connected to an active op-amp rather just resistance coupled. One will read a moderately low and fixed unchanging resistance. One will read a rather high and possibly fluctuating resistance. With power off using a TSR cable check resistance between the sleeve to the tip and the ring. I don't know about the gen 3 Scarletts, but earlier generations were impedance balanced and shouldn't be bothered with pin 3 grounded. My apologies if this has been covered as I didn't read all 7 pages.
