Enjoy Hi-Res Audio and Precision Equalization on iOS Devices

Partner our new HF Player app with your iOS device (and a quality set of headphones) to get your music sounding exactly the way you like it. Enjoy the same playback controls, track organization, and artwork display you’re used to but with the power of a touch-adjustable FIR equalizer offering 16,384 bands of equalization. Create and save your own EQ presets by genre, artist, or to match the different headphones in your collection. We even include presets created by leading musicians that are specially optimized for Onkyo headphones. Want your hi-res library on iPhone, iPod touch, or iPad? An in-app purchase enables 192 kHz/24-bit FLAC, WAV, and DSD decoding to bring better-than-CD sound to your portable setup*. Other features include a 48 kHz upsampling function (up to 192 kHz with the HF Player Pack) and crossfading capability. HF Player is a highly convenient way to get the best audio performance possible from your iOS device and headphones.

Note: App is compatible with iPhone 4S or later, iPod touch 5th generation or later, iPad 2 or later, and iPad mini running iOS 6 or later.

* DSD-IFF and DSF formats are converted to PCM before playback. An included DoP Output function allows output of native DSD audio to a DoP- and iPhone-compatible external device (such as a DAC) via an appropriate wired connection. Playback of high-resolution files increases demands on CPU and battery resources.
current app version: 1.2.1

A Fully Featured Audio Player

The clean and simple user interface will be familiar to regular iOS users. Once installed, the app automatically locates and loads the music stored on your device so you can start exploring the equalization possibilities on offer right away. Selectable 48 kHz upsampling and crossfading are also included, along with in-app access to social networks so you can tell your friends what you’re listening to.

Precision Equalizer with Preset Memory

Unlike other designs, our FIR equalizer is a phase-linear type allowing extensive audio adjustment without a loss in audio quality. Using a finger on the touchscreen, you can manipulate the frequency curve into any shape you like, tweaking bass, mid-bass, mid-range, and treble frequencies with precision. With 16,384 discrete bands of equalization, the range of possible adjustment is extensive, allowing you to get the sound you want for a given piece of music, or to suit the headphones in your collection. Memory presets allow you to name and save EQ curves for quick and easy retrieval.
