What Wavelet is

Wavelet is an Android system-wide audio equalizer designed to enhance headphone sound, and it works without root. Its AutoEq library contains more than 5,000 headphone profiles, with support for importing custom compensation data. A graphic equalizer provides nine independently adjustable bands. Additional tools include equal loudness, bass boost, reverberation, virtualizer, bass tuner, attenuator, limiter, and channel balance. Wavelet’s documentation lists audio processing for players including YouTube Music, Spotify, Plexamp, Samsung Music, and Podcast Addict; some players need extra setup. It also identifies TIDAL, SoundCloud, Amazon Music, YouTube, and other players as lacking audio-processing support. Enhanced session detection is experimental, works only on Android 10 or later, and requires DUMP permission. Wavelet has a free plan as well as paid features that require an in-app purchase or subscription. Its troubleshooting page describes an in-app purchase as a one-time payment without expiry, saved to the user’s Google account. The privacy policy states that accessed data is not shared or retained. Google Play or Huawei AppGallery may supply anonymized usage statistics and crash logs that do not contain sensitive user data. The Google Play listing names Thomas Johannes de Witt as the maker.
