DSP-Quattro
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.
