General information

High quality media player supporting USB audio DACs and HiRes audio chips found in the latest phones. Play up to any resolution and sample rate that the DAC supports! All popular and less popular formats are supported (beyond the formats that Android supports), including wav, flac, mp3, m4a, wavpack, SACD ISO, MQA and DSD.

This app is a must-have for every audiophile, bypassing all audio limits of Android. Whether you use our custom developed USB audio driver for USB DACs, our HiRes driver for internal audio chips or the standard Android driver, this app is one of the highest quality media players around.

Since version 5, the app now includes a MQA Core Decoder (in-app purchase required). MQA (Master Quality Authenticated) is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download, while also being backward compatible. The TIDAL streaming service supported by USB Audio Player PRO features many tracks in MQA and offers a great opportunity to experience MQA.

The MQA decoder will unfold the MQA stream from 44.1/48kHz to 88.2/96 kHz and can also be combined with USB DACs that feature a MQA renderer (e.g. AudioQuest DragonFly / iFi) for further unfolding to even higher sample rates.
Please visit http://mqa.co.uk for more information about MQA and https://www.extreamsd.com/index.php/mqa to read more about MQA inside the app.
