ReceptionRating · Positive reviews · Number of ratings

Audio Spectrum Analyzer Pro holds the better App Store score, 4.4 against 2.5. That said, the two scores are not equally well evidenced: Audio Spectrum Analyzer Pro has 239 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 65% of HD Music Parametric Equalizer's written reviews are positive against 57% of Audio Spectrum Analyzer Pro's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

HD Music Parametric Equalizer ships an update every 4 months, Audio Spectrum Analyzer Pro every 7 months. The most recent releases landed on November 11, 2026 and November 12, 2026 respectively.
