Music professionals looking to save a couple coin should look at the XA1. A realtime spectrum analyzer, the app is made to “give realtime feedback of the audio spectrum.” Meaning that when you go to mix your record, you can get the most accurate readings by giving you a visible reference for your sound. Keep in mind most hardware spectrum analyzers run in the $800 range. Doesn’t seem so pricey anymore, does it?
