Auria - DAW App for iPad

With the ability to play 48 mono or stereo 24bit/44.1 kHz (higher sample rates possible!) tracks simultaneously, record up to 24 of those tracks simultaneously (through any supported USB multichannel audio interface), and edit and mix with familiar tools and full parameter automation, it’s clear Auria sets a new standard for iPad multitracking.

48 Simultaneous tracks. Sessions are compatible with Logic, ProTools and Nuendo. VST plug-in support, as well as sharing via DropBox and SoundCloud.

This is a $50 app that runs on a $400 tablet with the kind of features and performance not possible on most people's desktop PC. Truly astonishing.
