Astra Frequix operates on a real-time digital signal processing architecture capable of generating eight independent oscillators simultaneously. Each oscillator features six waveform types: sine, square, triangle, sawtooth, pulse, and white noise. The phase-locked loop system ensures zero-drift frequency stability across the entire 0.1Hz to 20,000Hz spectrum with 0.01Hz precision.
The binaural beat generator calculates carrier and offset frequencies in real-time, producing precise interhemispheric phase differences for brainwave entrainment applications. Isochronic tone synthesis uses amplitude modulation with adjustable duty cycles from 10% to 90%, enabling complex rhythmic patterns for meditation and focus enhancement.
MIDI integration supports full controller mapping with velocity-sensitive frequency modulation and CC parameter control. The modulation matrix allows routing of LFOs, envelopes, and external MIDI data to any synthesis parameter, creating dynamic evolving soundscapes. Export functionality renders audio in WAV format at 44.1kHz or 48kHz sample rates with 16-bit or 24-bit depth.
Generate up to eight simultaneous frequencies with independent waveform selection, amplitude control, and phase adjustment. Each oscillator supports sine, square, triangle, sawtooth, pulse width modulation, and white noise generation with real-time parameter morphing.
Precision brainwave entrainment using carrier frequencies and calculated offset tones delivered through stereo channels. Supports delta, theta, alpha, beta, and gamma frequency ranges with adjustable beat intensity and smooth frequency transitions for meditation and focus applications.
Route up to six LFOs and four envelope generators to any synthesis parameter. Create evolving soundscapes with tempo-synced modulation, randomized parameter variation, and MIDI CC mapping for expressive real-time control over frequency, amplitude, and waveform characteristics.
Visual feedback displays FFT analysis with 4096-point resolution, showing harmonic content, frequency distribution, and amplitude peaks. Phase correlation meter ensures proper stereo imaging for binaural applications, while RMS and peak level meters monitor output dynamics.
Full MIDI implementation supports keyboard input for frequency selection, velocity modulation for amplitude control, and continuous controller mapping for real-time parameter adjustment. Compatible with USB MIDI interfaces and Bluetooth MIDI devices with sub-10ms latency.
Render synthesis sessions to uncompressed WAV files at 44.1kHz or 48kHz sample rates with 16-bit or 24-bit depth. Supports unlimited export duration, batch processing of preset sequences, and automatic normalization with configurable headroom for professional audio production workflows.
