Onkyo HF Player for iOS

APP Image

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 music sounding exactly the way you like it. Enjoy the same playback controls, track organization, and artwork you’re used to but with the power of a touch-adjustable FIR equalizer offering 16,384 bands of high-definition equalization. Create and save your own EQ presets by genre, artist, or to match the different headphones in your collection. We also include presets created by leading musicians that are optimized for Onkyo headphones. Want to hear your Hi-Res Audio library on iPhone, iPod touch, or iPad? An in-app purchase enables transfer and decoding of 192 kHz/24-bit FLAC, WAV, and DSD* 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 an easy 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 can be output as PCM or DoP. DoP Output function supports output of native DSD to DoP- and iPhone-compatible external devices (such as a DAC) via an appropriate wired connection. Playback of high-resolution files increases demands on CPU and battery resources.

A Fully Featured Audio Player

This intuitive 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 share what you’re listening to with friends.

Our Design Philosophy Ensures High-Quality Sound

When designing the HF Player’s digital filter, our engineering team took the unique characteristics of your device’s D/A converter and other associated hardware into consideration in order to achieve outstanding performance. Each filter coefficient is individually tuned according to sampling frequency for sound quality that surpasses theoretical signal-to-noise ratios, not only for Studio Master-quality Hi-Res Audio, but also for compressed audio files such as AAC and MP3. With HF Player, you can experience a clarity and vibrancy previously unobtainable on your mobile device.

High-Speed Processing Improves Audio Performance

As well as delivering stunning audio fidelity, HF Player takes advantage of your device’s rapid multi-core processing abilities without noticeably affecting battery life. Our design team analyzed conventional signal processing algorithms and utilized the parallel arithmetic capabilities of your device’s CPU to achieve higher processing speeds while improving energy efficiency and optimizing sound quality. This means you can enjoy premium sound on the go without your phone becoming sluggish or quickly draining its batteries.
