I tried the QA403(ASIO) with Smaart, and it works great. There is no control of the attenuation of course, but It seems to be at max att (?) I did not want to run both Smaart and 401X at the same time. Here is the noise floor comparison: ![Screenshot 2024-08-25 133437](https://canada1.discourse-cdn.com/flex032/uploads/quantasylum/original/2X/5/51747376751a81f651356c8172b1584bd93c70e8.png) ![dBxDr_R_260](https://canada1.discourse-cdn.com/flex032/uploads/quantasylum/original/2X/4/44e62f25ac02e10d6a024c8f8579a21577348a90.png) ---

Hi @alprada, thanks for the report. Do you think both apps are at +42 dBV full scale input? If that’s the case, then your -75.33dBu = -73.11 dBV, which is then 73.11 + 42 = -115 dBFS. They should be much closer than that. Maybe both weren’t in +42 dBV for the test? If you re-do, set both measurements to 0 dBV full scale input. ---

PS. Is anyone using Smaart or other for live sound dBSPL reporting? ---

I would assume Smaart is OFF, or a setting that needs to be changed? ---

Hi @alprada, thanks! When time permits can you set both apps to show power (eg RMS from 20 to 20 kHz)? ---

I dont see any settings for RMS on Smaart, it only has Average dept 1 - 10 , fast, slow. and SPL Fast,slow,peak and the frequency Weighting. ---

I have just tested it with Smaart v9 and AMFG ![Screenshot 2024-09-02 083300](https://canada1.discourse-cdn.com/flex032/uploads/quantasylum/original/2X/e/ecb4bf74742e302075ebc5fcd9252908721e6ef2.png) ![Screenshot 2024-09-02 085009](https://canada1.discourse-cdn.com/flex032/uploads/quantasylum/original/2X/6/6354509de6cc505b4395522fddc7e120cde44e31.png) Logging SPL vs time ---

Hi @alprada, OK, understood. I don’t think there’s going to be a way to compare then as the SPL and RMS are different things. The LAeq numbers in AFMG indicate A weighting and time-weighting. Are you doing live sound SPL monitoring?
