Adding Room EQ to Pure Music

- Download and install the latest version of Channel D Pure Music.
- Download and install the AU version of the MathAudio Room EQ plug-in. Pure Music doesn't support audio inputs that are necessary for the room measurement, but you can use free AU Lab program for the measurement. The measurement process is as follows:
- Download and install AU Lab.
- Launch AU Lab, found in /Applications/Utilities/
- From "Factory Configurations" menu select "Stereo In/Stereo Out". From "Audio Input Device" menu select your microphone input and from "Audio Output Device" menu select the output which corresponds to your speakers.
- Click the "Create Document" button at the bottom of the screen. Make sure that you hear the sound of the measurement microphone in one of your speakers when you touch the measurement microphone. If the sound is absent and you use USB speakers, you need to manually set the necessary inputs and outputs in AU Lab as it is described here.
- At the next screen, look for "Output 1" column and click the "Effects" dropdown, selecting "MathAudio Room EQ".
- Make sure that the green indicators show the presence of the mic signal (see figure below).
- Measure the frequency response of your room in accordance with the items 5 and 6 of the Room EQ Help manual. Make no less than 5-20 measurements within the area of possible locations of all listeners. Use the "Save preset" button to save the frequency response as a .snr file.
- Quit AU Lab without saving.
- Add Room EQ AU to Pure Music at Pure Music > Audio Setup/Audio Plug-Ins... > Audio Plug-Ins (then select MathAudio Room EQ in the left column as it is shown below).
