iZotope RX 7 Standard is the latest update to iZotope's audio repair software, which is considered a staple for recording, mastering, and audio-for-video post-processing. The software can operate either as a standalone application or as a plug-in for both Mac and Windows based DAWs and NLEs. From fixing common audio problems like noises, distortions, and inconsistent recordings to repairing severely damaged audio using Spectral Repair, RX can transform previously unusable audio into something usable.
The standard edition of RX 7 takes nearly all the modules provided in RX 6 Standard and implements a graphic overhaul more in line with iZotope's current aesthetic. You'll also find several new processes sure to help out in audio-restoration contexts, including Variable Time, Variable Pitch, Music Rebalance, and the Repair Assistant.
Variable Time lets you change the time stretch of an audio selection without affecting its pitch, while Variable Pitch does the opposite, allowing you to adjust the pitch of an audio selection without negatively impacting its duration. Previously, these processes were combined into one module.
Music Rebalance analyzes a full mix of music and allows you to rebalance the levels of its bass, vocals, drums, and harmonic content, doing so with four dedicated sliders. Do you have a bit of background music whose vocal line interferes with the dialogue? Use the Music Rebalance module to lower the offending vocal. Need to beef up the bass in an anemic mix that came your way? Use this tool to emphasize the bass with the bass slider.
Repair Assistant takes the concept behind iZotope's Mixing and Mastering Assistants and applies them to the restoration of audio. Simply select the audio you need to process, click on the Repair Assistant button, and let the program analyze your audio. It will offer you three options for processing (light, medium, and aggressive), and you can choose among them after auditioning each one. Next, hit render, and the Repair Assistant will automatically fix the issue.
All the tools work as they did in earlier versions of RX, allowing you to paint away audio problems on the spectrogram, as does the Module Chain, which reduces the number of mouse clicks required for using a series of processes. Many algorithms which did not provide real-time preview now do, which makes working a bit faster.
High-quality re-sampling and dithering are once again provided, as is batch processing. A detailed spectrum analyzer detects peaks automatically, and a suite of automatic, intelligent modules reduces manual tasks in the audio production workflow. RX 7 can be used as a standalone audio editor (including standalone but connected to your host via RX Connect, or as your DAW's audio editor, in the case of Logic Pro), and much of it can be used as a suite of plug-ins.
