Fortunately, the active card and parameters is displayed in the status bar, so it's easy to see if something has changed. IT will also randomly change sample rates. It will sometimes just crash for no reason - if you have multiple sound cards in your PC, it will sometimes randomly select a different interface during testing. Arta Steps is excellent for THD sweeps.ĪudioTester requires a licence but has a 30 day 'free' evaluation period. There are other useful functions for calculating inductance etc. The 'Steps' utility can perform swept THD vs frequency measurements. This is very useful software which is aimed at speaker development primarily, however it is extremely useful for other audio measurements. I cannot recommend this software due to issues with accuracy.Īrta (the free version has some minor limitations) I contacted the developer about it, and provided substantial proof that the software was indeed wrong, and my findings were disputed.
I found that the swept THD measurements were grossly inaccurate. I purchased a licence for it and used it for a few months until. DSSF3 is a really nice looking software suite.
