Spec score 7.5 #21 of 30 in Audio Enhancement Software

What it is

Wavelet is an Android system-wide equalizer for enhancing headphone sound without requiring root. Its AutoEq library contains more than 5,000 headphone profiles, and users can import custom compensation data. A nine-band graphic equalizer provides independent controls for each band. Additional tools include equal loudness, bass boost, reverberation, virtualizer, bass tuner, attenuator, limiter, and channel balance. Listed compatible players include YouTube Music, Spotify, Plexamp, Samsung Music, and Podcast Addict, although some require extra setup. TIDAL, SoundCloud, Amazon Music, YouTube, and other listed players lack audio-processing support. Enhanced session detection is experimental, requires Android 10 or later, and needs DUMP permission. Wavelet uses a freemium model: some functions require an in-app purchase or subscription. Troubleshooting information describes that purchase as a one-time payment without expiry, saved to the user’s Google account. The privacy policy says accessed data is not shared or retained. Google Play or Huawei AppGallery may provide anonymized statistics and crash logs.
