AURA Synapse Pro is a professional-grade mastering suite that runs entirely in your browser using Web Audio API and AudioWorklet technology. Load any audio file and process it through a complete mastering chain: 9-band parametric EQ, multiband dynamics compressor, harmonic exciter, stereo imaging, and true peak limiter. Export your mastered audio as high-quality WAV files.
Shape your sound with precision using nine frequency bands spanning 20Hz to 8kHz. Each band features adjustable gain with real-time EQ curve visualization. Low shelf, peaking, and high shelf filter types provide surgical control over your frequency balance.
Control dynamics with threshold, ratio, attack, release, and knee parameters. Add warmth and presence with the harmonic exciter's soft-clipping saturation. Achieve punchy, controlled mixes with professional-grade dynamics processing.
Widen or narrow your stereo image with mid-side processing. The bass mono control keeps low frequencies centered for better speaker translation. The true peak limiter prevents clipping while maximizing loudness for streaming platforms or CD mastering.
Start with five professionally crafted presets: Bright Master, Warm Analog, Punchy Mix, Radio Ready, and Transparent. Save your own custom presets for instant recall. Real-time spectrum analyzer and stereo level meters provide visual feedback throughout the mastering process.
Load any audio file (WAV, MP3, OGG, FLAC) and start mastering immediately with Synapse Pro's free tier (3 sessions per day). Upgrade to Synapse PRO for $7.99/month or $79/year for unlimited sessions, WAV export, and custom preset storage.
