The TEAC HR Audio Player for iOS is a Hi-Res Audio Playback App for iOS devices (*1), allowing DSD 11.2MHz and PCM/FLAC 24-bit/192Hz playback on TEAC Portable DACs (*2) via single Lighting-USB cable.
If you use the App with an iOS device alone, Hi-Res Audio data 88.2kHz or higher will be converted to 44.1kHz, and delivers analog audio signal from Earphone jack on the iOS device.
After In-App purchase (*3), the TEAC HR Audio Player for iOS also works with non-TEAC DACs/Headphone Amplifiers, or iOS device alone.
(*4) You will access all functions including PCM 24-bit/192kHz playback and DoP/PCM output for DSD data via Apple's Lightning-USB Camera Adapter or iPad Camera Connection Kit.
The equalizer provides a conventional SD mode and more precise HD mode that processes the audio signal in 64-bit.
