Why MangoAmp Stands Apart

Engineered specifically for music purists, terminal lovers, and hardware phone enthusiasts.

01 // DSP & AUDIO

AutoEq Headphone Compensation

Direct integration with thousands of headphone frequency response measurements. MangoAmp translates complex parametric EQ curves into a calibrated 10-band hardware graphic equalizer with safe preamplification to prevent clipping.

[31Hz: +2.1dB | 125Hz: -0.5dB | 1kHz: +1.2dB | 16kHz: -1.0dB]

02 // ARCHITECTURE

AndroidX Media3 Service

Built entirely on MediaSessionService and ExoPlayer. Delivers uninterrupted background audio that survives aggressive OEM battery killers, integrates with Bluetooth car stereos, and draws high-res lockscreen notification cards.

[FOREGROUND_SERVICE_MEDIA_PLAYBACK: ACTIVE // WAKELOCK: HELD]

03 // HARDWARE

Physical Keyboard & QWERTY First

Tuned for devices like the Unihertz Titan, Titan Pocket, BlackBerry KEYone/KEY2, and Clicks keyboards. Full vi/cmus navigation keys (j/k, Enter, /, z/x/c/v/b) alongside a touch softkey bar.

[WINAMP + CMUS SHORTCUT COMPLIANCE: 100%]

04 // STREAMING

Subsonic & Navidrome REST Sync

Connects seamlessly to Navidrome, LMS, Airsonic, and Subsonic-compatible servers. Live server library statistics (#ARTISTS, #ALBUMS, #SONGS), synchronized LRC lyric streaming, and internet radio support.

05 // VISUALS

Pixelated Cover Art & Oscilloscope

Nearest-neighbor downsampling transforms modern high-resolution covers into genuine 16x16 or 32x32 retro pixel art. Combined with dynamic 16-band spectrum visualizers and synchronized oscilloscope waveforms.

[RES: 16x16 NEAREST-NEIGHBOR // SCANLINES: CRT_PHOSPHOR]

06 // PRIVACY

Zero Telemetry, Zero Bloat

No ad SDKs, no tracking pixels, and no cloud accounts required. The app communicates strictly with your designated private music server or local storage.

[DATA EXFILTRATION: 0 BYTES // PRIVACY: GUARANTEED]
