8. RMAA Test Guide The Xonar DX driver CD includes RightMark Audio Analyzer (RMAA) v5.6, a popular software intended for testing the quality of audio equipment, be it a sound card, portable MP3 player, consumer CD/DVD player, or a speaker system. The measurements are conducted by playing and recording test signals, and using frequency analysis algorithms. The following provides a step-by-step loop-back test guide for your Xonar DX audio card. 8.
4. Go to the Mixer Recording page and select “Line In” as the recording source. Click “Reset” to make sure the recording volume is on the default highest level (0dB). This allows you to get realistic output and input quality ratings for the Xonar DX audio card. 4 You should use an external 3.5mm line cable as follows (as short as possible) to connect the Front-Out jack to the Line-In jack for loop-back testing. In that case, please select “Line In” as the recording source on the mixer page. 3.
5. Click “Reset” on the playback volume mixer page to keep the volume setting on default. 6.
8.2 Configuration and Test with RMAA Start RMAA and follow the setup procedure below. 1. Select both of the playback/recording devices as “ASUS Xonar DX Audio”. 2. Select 24bit and 48KHz for the test signals. (If you change the format here, please remember to go back to set the same sample rate output in the Xonar DX Audio Center) 1 3. 2 Click “Test options” button in RMAA and check “Analyze noise and distortion only in 20Hz-20KHz range” (audio in-band for human hearing) in the General tab.
4. Go to the Sound Card tab and select “DirectSound” as the Driver Model (because Windows MME mode doesn’t support high-resolution 24bit audio playback and the data may be manipulated by Windows so that the real hardware quality can not be measured properly.) 4 5.
6. Check if the levels shown in the Adjusting level window are OK (the level meter will be green). 6 7. If the recording volume level is not high enough, please check and make the WAVE and Master Volume have been at the maximum level; Instead, if the recording volume level is too high, please lower the WAVE and Master volumes gradually until the level is ok.
8. Begin the test by clicking the “Done” button. If you cannot get the level to be “OK” after the previous step, click “Done” anyways and proceed. 8 9. Enter “ASUS Xonar DX Audio” in the New slot name and select one Empty slot. Then click “OK”.
10. RMAA will pop up the Test results window. You can click the “Select” checkbox and click to “Make html report”. 10 11. Check and key in the report name/options as follows and then click “OK”.
8.3 RMAA Testing Results Open the html file you created and saved in the test above, and it will display the report with both data and plots in your browser. The following report is a sample and you can see how high-fidelity and crystal-clean the Xonar DX audio card is for both output and input (one of the world’s finest sound cards, it has higher quality than most CE devices.) You can also try testing the performance for other sample rates and bit-depths with the same procedure.
