frekvens vs QUARK Play

Frekvens is a frequency shifter and delay effect. Unlike a pitch shifter all frequencies are shifted linearly and then fed back into itself using the stereo delay unit. The frequency shifting is achieved with single sideband modulation using a hilbert transform and an infinite impulse response filter for fast computations. Frekvens also comes with a high and low pass filter and a lfo for modulating the delay play head. - frequency shifter - high, low pass filter - stereo delay - core midi cc input - audiobus - inter app audio - audio unit extension - save, load

QUARK Play easily transforms up to four iOS devices into a wireless, quadraphonic sound system. Place iPhones, iPads, and/or Macs around the space (or connect them to bluetooth speakers), hit play on the host device, and build a true, immersive surround sound environment anywhere. The Quadraphonic Universally Accessible Resource Kit (QUARK) is open source software used in Digital Audio Workstations (DAWs) and similar platforms to encode four channels of discrete audio into two channel (standard stereo) audio, then back to four channels again. This allows for the distribution of four-channel spatial recordings via widely accessible two-channel formats such as vinyl, cassette, and radio, as well as digital platforms such as YouTube, Spotify, and Qobuz. QUARK is made possible by dublab & the National Endowment for the Arts.
