‘Intuitive’ audio restoration from Cedar Audio’s Retouch 5
The latest major upgrade to Cedar Audio’s Cambridge V8 audio restoration and speech enhancement system has been released in the form of Retouch 5, boasting a wealth of additional tools and improvements. All new features have been designed in order to facilitate improved spectrographic editing by allowing users to quickly and effectively manipulate and restore audio.
One such key feature is an ‘intuitive’ variable area paintbrush tool that makes it possible to select areas of audio by painting over them in the spectrogram. Multiple areas can be painted at any given time, and an erase function makes it possible to trim existing areas or create complex shapes that most accurately represent the audio to be treated.
Meanwhile, a newly introduced ‘volume’ processing mode allows users to either alter the volume of any marked audio, or everything but the marked audio in the range +20dB to -150dB. The former option makes it possible to accentuate certain audio and to suppress unwanted noises, whilst the latter eliminates everything but the marked audio to reveal individual sounds.
Additional new features comprise the inclusion of a pitch shifter tool (available in patch and copy modes), which invoke a genuine pitch shift formula that takes into account the relative pitches of components within the audio selection. When used together with a new Midi Note scale on the frequency axis, this tool allows users to correct the pitches of incorrect notes within musical material.
A final key feature is a previewing tool which allows users to audition their edits before transferring the material back into the file processor, load and process unlimited file lengths, facilitates improved transport capabilities and time markers, and boasts a more configurable display when compared to previous versions.
