HF Player

Onkyo HF Player Unlocks High-Resolution Audio Playback on Your Android Device

Most music apps compress your files, stripping away sonic details you never knew existed. Onkyo HF Player bypasses Android’s internal audio mixer, delivering bit-perfect playback for FLAC, DSD, and WAV files up to 384 kHz/32-bit. You gain direct control over digital-to-analog conversion, equalization curves, and crossfeed settings — turning your smartphone into a dedicated portable audio player.

Core Audio Processing Tools

The player operates as a standalone audio engine with three distinct processing stages. The first stage handles file decoding: it reads native DSD (DSD64/DSD128/DSD256) without transcoding to PCM, preserving the original waveform shape. The second stage applies digital filtering through five selectable filter types — including slow roll-off, fast roll-off, and apodizing filters — each altering transient response and phase coherence. The third stage manages output routing through the built-in USB Audio Class 2.0 driver, enabling direct connection to external DACs without Android’s resampling layer.

• Native DSD playback engine decodes DSD64, DSD128, and DSD256 files without PCM conversion, preserving full frequency response.
• 5-mode digital filter selection adjusts roll-off steepness and phase behavior for precise tonal shaping.
• USB Audio Class 2.0 driver bypasses Android mixer when connected to external DACs via OTG cable.

Equalization and Sound Shaping Tools

HF Player includes a parametric equalizer with 10 independent bands, each adjustable in frequency (20 Hz–20 kHz), gain (±12 dB), and Q factor (0.4–10.0). Users can enable auto-phase compensation to prevent phase shift accumulation when applying multiple bands. The crossfeed processor simulates speaker-like soundstage by mixing left and right channels at selectable frequency cutoffs (700 Hz, 1.5 kHz, 3 kHz) and intensity levels (low/medium/high). A built-in limiter prevents clipping when equalization boosts push signal levels beyond 0 dBFS.

File Management and Playback Organization

The app scans device storage and external SD cards for audio files, organizing them by folder structure or metadata tags. Users can create custom playlists with drag-and-drop reordering, apply gapless playback between consecutive tracks, and set replay gain normalization across albums. The playback queue supports up to 999 tracks with shuffle and repeat modes. A folder-based navigation mode displays the raw file hierarchy, useful for organizing live recordings or classical compilations.

Technical Performance and Output Control

Bit-perfect output mode disables all digital volume control, sending the raw audio stream to the DAC at its native bit depth and sample rate. The app supports 32-bit float processing for internal mixing and equalization, reducing rounding errors during multi-band adjustments. Output gain can be adjusted in 0.5 dB increments from -∞ to +24 dB. Sample rate conversion is available through four algorithms: linear interpolation, cubic interpolation, sinc interpolation, and band-limited interpolation.

Download mobile app now

Consider downloading Onkyo HF Player if you require native DSD playback, parametric equalization with phase compensation, or direct USB DAC connectivity without Android’s resampling. The app functions as a complete audio processor for critical listening sessions.

This audio playback application requires Android 8.0 or higher and a device with sufficient processing power for real-time DSD decoding and multi-band equalization. High-resolution audio files (DSD, 24-bit FLAC, WAV) may consume significant storage space and battery during playback. USB DAC functionality requires an OTG adapter and a compatible external DAC. In-app purchases are available for additional features. Network connection is required for initial download and optional streaming features; data usage applies when accessing online content. Age restrictions may apply in some regions.
