This stem separation tool could prove incredibly useful for producers looking to create instant acapellas or instrumentals to existing songs.Digital Audio Workstations are capable of just about anything these days, from laying down the first drum pattern of a track, right up to the final master.However, there are still several dedicated audio-editing applications that focus on one (or a few) specific audio-editing functions, such as mastering, remastering or audio restoration.
Recently, Acon Digital released a 7.2 update for their popular audio editor: Acoustica. Acoustica Audio Editor Full MacOS CatalinaThis update integrates several new intriguing features, as well as full macOS Catalina support. When it comes to programs similar to this, the same question always remains. Does Acon Digital supersede the audio editing, mastering and restoration processes available in Logic, Pro Tools or other major DAWs A Spectral Powerhouse Before we take a look at the quality and workflow of Acoustica 7.2, lets take a quick look at the software specifics, and what this program is actually capable of. Acoustica 7.2 is available as a Standard Edition (49.90) and a Premium Edition (169.90). Both these downloads include the Acoustica software and a highly innovative new Remix tool for intelligent stem separation. The Premium edition includes a new Extract Dialogue tool, an automated tool for removing pesky background noise from dialogue. The Premium Edition also includes other advanced features such as spectral editing with retouch algorithms and multi-channel support up to 7.1 surround. Another huge bonus of the Premium Edition is the inclusion of Acon Digitals incredibly powerful, acclaimed VST AU plugins; Verberate 2, Equalize 2, Restoration Suite 2 and their Mastering Suite. Its worth noting that purchasing these plugins individually would set you back around twice as much as Acoustica Premium, so the value for money here is pretty remarkable. Dynamic Workflow To truly put this product to the test, I found a few samples with moderate amounts of artefacts and background noise. After dragging-and-dropping the file into Acoustica, a waveform visualizer appears (this can also be viewed as a spectrogram), with various sound specifications below. Along the bottom of the interface, you have a Media File Browser, a Processing Chain module and a Loudness Meter Spectrum Analyser module. Right away, you get a sense of the power and audio editing potential of Acoustica. This is clearly a program that is designed not only for a rapid, no-nonsense workflow, but also creative versatility and accuracy. One of the first things I noticed when playing around with audio files in Acoustica was the level of detail in the selection tools. Acousticas spectral editing mode then allows you to isolate and process issues within the spectrogram visualizer. This opens up an entire world of sonic possibilities when it comes to sound design, and fine-tuning your audio clean-up to an incredible level of precision. A Retouch tool also allows you to clean up pesky artefacts by actually using waveform information from other, unaffected areas of the spectrogram. Please note the spectral editing mode is only available in the Premium version of Acoustica). After a fairly low learning curve, my samples were more-or-less completely clean, with various noises and artefacts either completely removed or heavily attenuated. Overall, I found the workflow and usability of Acoustica pretty mindblowing, and VERY easy to navigate. Split the Difference Arguably the most significant improvement in the 7.2 update is the Remix feature. This tool allows you to separate an existing mix into individual stems, automatically analyzing the audio signal and isolating each part, eg.
