What it is
DSP-Quattro is a macOS application for audio editing, mastering, audio CD-ROM burning, plug-in hosting, and batch processing. Its editor works with multiple audio formats and supports waveform editing, sound enhancement, and real-time processing. The application hosts 64-bit Audio Unit effects and instruments, but it does not load VST plug-ins. Version 6 requires macOS 10.14 or later 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 it does not allow saving or exporting audio, exporting DDP, or burning Audio CD-ROMs. The new license is listed at $99 a month. The $49 a month upgrade is limited to 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.
