The Pro version of SOAR challenges you to control your own 10-band graphic EQ while attempting to match the timbre of a 'target' sound.

The App will randomly change the boost/cut for up to 10 selected center frequencies providing a timbre change to the original source. You then adjust your own EQ in an attempt to achieve an identical timbre change. When satisfied, you click 'submit' to find out how close your settings were to the app's.

Several levels of difficulty are provided:
• +12, 0, -12 [ 3 step, easy ]
• +12, +6, 0, -6 , -12 [ 5 step, medium ]
• +12, +9, +6, +3, 0, -3, -6, -9, -12 [ 9 step, difficult ]
• single dB precision [ 25 step, crazy hard ]

Use with GarageBand in IAAE mode, or with compatible DAWs (not included) in AUv3 mode, or by itself in stand-alone mode. In stand-alone mode, only pink noise can be used as a sound source. IAAE and AUv3 modes allow you to use any sound as a source.

Toggle between your EQ, the target EQ, or the un-EQ'd source while working.

Start out with one or two bands only, in easy mode, then gradually increase the number of bands and difficulty to improve your performance providing hours of challenging listening.
