Parametric EQ with AutoEQ

TuneWell’s own equalizer, computed in 64-bit, runs inside both of its playback paths. Up to 32 bands of peaking and shelving filters, shown as a curve, plus a preamp. Headphone corrections from the AutoEq project are built in, more than 6,000 measurements, with a choice of 5, 8 or 10 filters. Presets import from Poweramp, from Equalizer APO parametric text (as AutoEq, squig.link and REW write it) and from GraphicEQ text, and export through the share sheet.

High-Res Audio

FLAC, WAV (including RF64 and BW64), AIFF, DSD (DSF and DFF, including DST-compressed DFF, up to DSD512), WMA and WMA Lossless, MP3, AAC, OGG and Opus. ALAC, APE, WavPack and E-AC-3 (Dolby Digital Plus) play where the phone’s own decoder supports them.

Bit-Perfect USB Output

Where the phone maker offers a bit-perfect USB path, TuneWell sends audio to a USB DAC untouched. DSD can go out as DoP to DACs that accept it, and PCM above 192 kHz plays at the file’s own rate. On newer phones without that path, TuneWell asks the system to run the DAC at each track’s sample rate. Output diagnostics in Settings show the output device and its formats, with a DoP test and a USB DAC test.

32-Bit Float, End to End

Outside bit-perfect mode, decoding and output stay in 32-bit float with no 16-bit truncation, and DSD converted to PCM goes through a multi-stage Kaiser filter chain.

Plays What Others Can’t

WMA and WMA Lossless files that other players reject. TuneWell reads the ASF container itself and decodes it with its own bundled engine.

Playback

Gapless playback for the formats the phone decodes (tracks TuneWell decodes itself, such as DSD and WAV, still have a short pause between them), crossfade from 1 to 10 seconds, a fade on pause, picking up where you stopped when the app starts, and a sleep timer of 15, 30, 45, 60 or 90 minutes or to the end of the current track.

Now Playing

An optional waveform seek bar and visualizer, a background tinted from the album art, generated artwork for tracks without a cover, and a lock-screen player on newer phones.

Lyrics

Synced and plain lyrics embedded in the file, .lrc files next to the track, and optional online lyrics from LRCLIB, off by default. Open them full screen, or follow the live lyric line in the player.

Track Info and Audio Quality

One sheet with the file’s format, sample rate, bit depth and bit rate, an audio quality report analysed on the phone, and an optional metadata lookup from MusicBrainz with covers from the Cover Art Archive, off by default. Changes stay inside TuneWell and never touch your music files.

Smart Playlists
