Tinnitus Aid is for people who want to work with their tinnitus frequency directly. You apply a bandpass filter to any sound or mix and move it up and down until it matches the ringing, then add a bandstop filter at that frequency to create a mask with that band removed. Phase4 Mobile points to published research on notched sound therapy as the basis for the approach. The controls are detailed: a range of 128 Hz to 16 kHz, filter widths from 0.1 to 4.0 octaves at 1 Hz resolution, and separate frequencies and widths for each ear with a balance control. The free version includes natural sounds, unlimited mixes of up to 4 sounds, a timer with a slow fade and a sample of the filters. A Premium subscription removes ads and gives unlimited filter use and more than 250 sounds; the US store lists Premium at $14.99 and $39.99 without naming the periods. There is no CBT or education content.
