Effect Engine Music Player

This is a high-fidelity music player that brings together bit-perfect original sound quality and customizable DSP effects in one app. Seamlessly stream and enjoy music not only stored on your device but also from connected cloud and network storage.

■ Original Sound Preservation, Bit-Perfect Output & Hi-Res Driver
Maintains the original sample rate and bit depth of your audio files to minimize unnecessary conversions whenever possible. When Bit-Perfect mode is enabled, all DSP effects are bypassed to deliver the pure, unaltered signal. Utilizing the Hi-Res driver, it achieves true Bit-Perfect playback and supports Native DSD and DoP output.

Note: Native DSD is not guaranteed to work on all devices. If unsupported, playback is still available via PCM output.

■ USB DAC Exclusive Mode
Utilizes a custom-built USB audio path to directly access compatible USB DACs, bypassing the Android audio mixer for an independent output configuration. You can finely adjust the USB Sample Rate, Bit Depth, Packet Size, and DSD Mode (Native DSD / DoP / DSD→PCM). Immediate hardware volume control is also supported for compatible DACs.

Note: Due to the vast variety of USB DACs, compatibility with all devices cannot be guaranteed. If your device does not work, please contact the developer for potential updates.

■ Bluetooth Exclusive Mode
Bypassing the Android mixer to access the Bluetooth device directly, audio plays at its original sample rate. Control the codec in-app to fine-tune quality and resolution. High-sample-rate codecs like LDAC, aptX Adaptive, and LHDC output directly, with no conversion.

■ EffectEngine DSP
Sculpt your music to your exact taste with 10 powerful audio effects.
• Clear Silent — Cleans up background noise for a pitch-black, silent background.
• LAUR — Restores the airiness and fine micro-details in the high frequencies.
• Heavy Bass — Enhances the weight and depth of the low end.
• Treble Control — Adjusts treble quantity, phase, and sibilance.
• Ultra Stage — Expands soundstage width and depth.
• Clear Sound — Provides distinct, crystal-clear sonic outlines.
• Hyper Attack — Controls the punch and attack intensity of transients.
• Harmonics — Adjusts note thickness and organic cohesiveness by generating overtones.
• R2R Processor — Emulates the unique texture and harmonics characteristic of R2R DACs.
• PCM to DSD — Converts and outputs PCM audio as DSD.
Customized settings can be saved as presets for quick access.

■ Precision Conversion, SoX Resampler
Handles upsampling and bit depth conversion using the industry-renowned SoX resampler. You can manually configure quality, phase response, dithering, and cutoff frequencies. For the Hi-Res driver, it also allows adjustments to the sample rate, bit depth, and buffer size.

■ Library & Playback
• Browse by Track, Album, Artist, Genre, Folder, and File Explorer.
• Create and edit playlists, M3U export, Favorites, and Quick Search.
• Toggle between Album Art, Spectrum Visualizer, and Lyrics.

■ Cloud and Network Streaming
It connects to Google Drive, OneDrive cloud, and SMB, FTP, SFTP, WebDAV network storage to play music that is not stored in the device. It supports streaming external devices through DLNA/UPnP, remote playback based on its own renderer, and sound source sharing between devices by opening a media server.

■ Convenience Features
• Supports Korean, English, Japanese, and Chinese with instant switching (no app restart required).
• UI scaling adjustments.
• Backup and restore settings, DSP presets, favorites, and playlists.
