Effect Engine Music Player

A high-resolution music player that keeps your audio true to the source — and lets you shape it to your taste. Enjoy music stored on your device, your own cloud and network storage, and even web browser streaming, all in one flow.

■ Source-true playback, Bit-Perfect output, HiRes driver
Keeps the source sample rate and bit depth wherever possible, avoiding unnecessary conversion. Bit-Perfect mode turns off every effect and outputs the pure original signal, while the HiRes driver enables true bit-perfect playback with Native DSD and DoP output.
* Native DSD is not guaranteed on every device. Unsupported devices automatically play via PCM output.

■ USB DAC Exclusive Mode
A custom-built USB audio path accesses compatible USB DACs directly, bypassing the Android mixer for independent output. Fine-tune USB Sample Rate, Bit Depth, Packet Size, and DSD Mode (Native DSD / DoP / DSD→PCM). DACs with hardware volume get instant volume control.
* USB DACs vary widely, so compatibility with every device is not guaranteed. If yours does not work, contact the developer — support can be added in an update.

■ Bluetooth Exclusive Mode
Accesses Bluetooth audio devices directly and bypasses the Android mixer, outputting at the source sample rate. Control the codec, quality, and resolution from within the app. High-resolution codecs such as LDAC, aptX Adaptive, and LHDC output directly without sample-rate conversion.

■ Browser Streaming
The built-in browser routes web page audio into the app's DSP and output chain. Web streaming plays through the same path as local files — combine it with USB DAC Exclusive Mode to enjoy web music with independent output and full sound processing.

■ EffectEngine Sound Effects
Ten effects to shape the character of your music:
• Clear Silent — cleans background noise for pitch-black silence
• LAUR — restores lost high-frequency air and fine detail
• Heavy Bass — adds weight and depth to the low end
• Treble Control — adjusts treble amount, phase, and sibilance
• Ultra Stage — widens the stage and deepens the sense of distance
• Clear Sound — crisp, clean outlines
• Hyper Attack — controls the intensity of transients
• Harmonics — generates harmonics for body and organic flow
• R2R Processor — emulates the texture and harmonics of R2R DACs
• PCM to DSD — converts PCM sources to DSD output
Save your adjustments as presets and recall them anytime.

■ Precision conversion with the SoX resampler
Upsampling and bit-depth conversion are handled by the SoX resampler, with direct control over quality, phase response, dithering, and cutoff. The HiRes driver additionally adjusts sample rate, bit depth, and buffer size.

■ Library & Playback
• Browse by song, album, artist, genre, folder, or file explorer
• Integrate network storage into your library — browse, search, and sort remote music just like local files
• Create and edit playlists, export M3U, favorites, quick search
• Switch between album art / spectrum visualizer / lyrics
• Gapless playback, shuffle & repeat, real-time output format display
• Mono downmix, channel swap, and other playback options

■ Cloud & Network Streaming
Connect Google Drive and OneDrive, plus SMB, FTP, SFTP, and WebDAV network storage to play music not stored on your device. Supports DLNA/UPnP streaming to external devices, remote playback via the built-in renderer, and sharing music between devices through the built-in media server.

■ Convenience
• Korean, English, Japanese, and Chinese — switch instantly, no restart
• UI scale adjustment, runtime theme and accent-color customization
• Back up and restore settings, effect presets, favorites, and playlists
• Simple, minimal interface

The microphone permission is optional. It is only required for the spectrum visualizer.
