Bit-Perfect Playback — Your Phone Becomes an Audiophile Source

Most music apps downsample your audio before it reaches your ears, even when playing so-called lossless files. USB Audio Player HiRes sends the full-resolution audio stream directly to your external USB DAC, completely bypassing the phone internal audio processing chain. The result is bit-perfect playback that lets you hear every micro-detail, spatial cue, and harmonic overtone the artist and producer intended.

Whether you own a portable DAC from iFi, Chord, AudioQuest, or FiiO, or a desktop unit from Topping, SMSL, or Schiit — this app ensures your investment delivers its full potential when driven from your iPhone or iPad.

Supported Audio Formats

FLAC (up to 384kHz/32bit), DSD (DSD64, DSD128, DSD256, DSD512), MQA (full decoder), ALAC (Apple Lossless), WAV, AIFF, APE (Monkey Audio), WavPack, Ogg Vorbis, MP3, AAC, and OPUS. Virtually every audio format audiophiles use is supported natively.

USB DAC Compatibility

Works with any USB Audio Class 1.0 and 2.0 compliant DAC connected via Lightning or USB-C adapter. Tested and verified with popular DACs from iFi (xDSD, Go Bar, hip-dac), Chord (Mojo 2, Hugo 2), AudioQuest (DragonFly Red, Cobalt), FiiO (KA5, BTR7), Topping (DX5, E50), and many more. If your DAC works with a computer via USB, it will work with this app.
