DSP-Quattro vs HOFA CD-Burn.DDP.Master

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.

HOFA CD-Burn.DDP.Master is a standalone mastering and pre-mastering application for CD, DDP, vinyl, and online distribution projects.

Album sequencing, multi-CD projects, multi-session CDs, and batch processing are supported. Delivery options include DDP images, WAV, AIFF, MP3, and an iTunes itmsp package. HOFA plugins are included at no additional cost in the app, with automatable parameters, and the software connects to HOFA DDP Player Maker for client-review players. The standard edition does not list third-party VST3 or AU plugins, plugin-chain presets, clip-based plugin processing, or true-peak normalization; those are listed for PRO. It runs on macOS 10.13 or later and Windows 10 or later. The listed plan costs 89.90 EUR once, with a 14-day free trial and offline activation.
