Developer Stefano Daino has released version 6.1.1 of DSP-Quattro, a macOS application for audio file editing, CD mastering, and batch processing. The update brings compatibility with macOS 26 Tahoe and adds several workflow enhancements to the software.
The batch processor gains CD-Text management capabilities, and the audio editor introduces a Change Length and BPM command for sample-accurate adjustments. Users can play audio files backward through new transport controls, and channel strips feature pitch adjustment options. The advanced VU-Meters window, which measures LUFS and TruePeak levels, operates as a standalone tool or as an insert plugin.
The software requires macOS 10.14 Mojave as its minimum system requirement. DSP-Quattro costs $99 during its introductory period, up from the regular $129 price. Users who purchased version 5 after July 1, 2025, receive a free upgrade, and other users pay $39 for the update.
