DSP-Quattro vs Soren

DSP-Quattro is a macOS application for editing and mastering audio files, burning audio CD-ROMs, hosting plug-ins, and processing batches. Its editor supports multiple audio formats, waveform editing, sound enhancement, and real-time processing. It hosts 64-bit Audio Unit effects and instruments, but does not load VST plug-ins. Version 6 requires macOS 10.14 or newer and runs natively on Intel and Apple Silicon Macs. Listed delivery formats include AIFF, WAVE, MP3, M4A, CAF, FLAC, AAC, DDP, raw binary, and dual L/R mono. The demo has no time limit, but saving or exporting audio, exporting DDP, and burning audio CD-ROM are unavailable in it. The new license is listed at $99 a month; the $49 a month upgrade is for customers registered to a previous DSP-Quattro or DSP-AudioCDBuilder version. The license is for personal use and belongs to one owner. Email support is listed, and refunds may be requested within 14 days after purchase.

Soren is a standalone app for automated audio mastering, not a DAW plugin. Its Mix Agent analyzes mixes before mastering and suggests changes for tonal imbalance and resonances. Users can choose among 10 genre profiles and 27 curated Smart References, or upload a reference track for analysis of spectral balance, dynamics, and tonal qualities. Controls include spectral and stereo processing toggles, custom LUFS targeting, and safeguards against over-processing. Export formats are WAV at 44.1 or 48 kHz in 16 or 24 bit, and MP3 at 320 or 256 kbps, with three True Peak limiting options. Processing happens locally; the maker says internet access is not needed after initial online activation. Desktop requirements are macOS 12 or higher or Windows 10/11, with at least 8 GB RAM recommended. The page lists support for files up to 90 minutes on Apple Silicon M1 with 16 GB RAM, and says Soren is available for iPhone and iPad. A free trial is available, and pricing starts at €249.
