Frequently Asked Questions

 
   
 
 
  Q: Minimum OS Requirements? 
  A: Mac: macOS 10.10 (Yosemite) or later
PC: Windows 10 v1703 (build 15063) or later
 
       
  Q: Why App Store?  
  A: Yes, App Store is frustrating.
For buyers, the registration procedure is overly cumbersome. For sellers,about 30% sales will be cut off, not to mention the restrictive rules of getting app approved. Fortunately, there are also benefits for both. App Store resolves many common problems of software distribution, for example:
- Trusted/secured payment
- License management/transfer/sharing
- User account, invoice/receipt and tax
- Auto update of purchased apps
- Anti-virus
- Anti-piracy
- App search
- Download hosting & bandwidth
If each software developer has to set up its own solution to provide the above services, the developer will be much distracted from developing new apps or improving existing apps. And also, the app's final price will be much higher due to the additional distribution overhead occured which has no contribution to the app's functionality & quality. Thus, the buyer may end up with paying more but the transaction may not necessarily be easier -- think about the concern of giving credit card to a stranger, filling forms with personal information, manually typing in the received license key and dealing with activation errors...etc.

Related question: Side-Load Possible?

 
       
  Q: Side-Load Possible?  
  A: Unfortunately, installing the app on a computer without going through the App Store (side-load) is not supported because apps designed for App Store are based on the new sandbox technology. Either Apple or Microsoft are enforcing sandbox technologies on their latest operating systems (macOS or Windows), which require App Store as the centralized distributer. Developers are encouraged to adopt the new sandbox technologies for being more "future proof" in the new ecosystem, at a cost of losing backward compatibility to the traditional package based installation.

  Q: Too Expensive?  
  A: Yes, this is surely not a life-changing app that everybody needs everyday. But it still requires comparable amount of time, efforts and knowledge to develop. It may make total sense for those individuals who have been needing such a specialized tool for years, or completely the opposite for others. From developers' perspective, this is a typical avoidable project with the warnings of technical challenges, narrow niche market and foreseeable negative ROI. But if someone is willing to commit, would it worth being recognized?

Related question: Too Cheap?

 
       
  Q: Too Cheap?  
  A: Well, inexpensive ≠ inferior quality. The app is not an impromptu product -- neither an academic demo nor an experimental prototype. It is nothing lack of deep thoughts, algorithmic research, software engineering and originality. However, it is certainly not flawless and may contain bugs -- like with any other software products including those million-dollar apps. Yes, it may be a poor product in terms of profitability. The birth of the app would not happen if it was solely driven by commercial motivation.

  Q: For Win8/7/Vista/XP?  
  A: Unfortunately, this app is based on the new sandbox technology which is not backward compatible with Win8/7/Vista/XP.

  Q: For Linux?  
  A: Unfortunately, there is no plan to make a native app for Linux. However, the PC version of the app may work in VirtualBox on Linux. But Wine is not supported.  
       
  Q: Plugin Version?  
  A: Developing a VST plugin with the same codec is possible and is in planing but not with high priority. There is no foreseeable schedule for now due to short of resources. It is supposed to be a very focused codec plugin, with the exact same core engine but without the extra fine-tuning tools which can be substituted by other plugins. The level meter will be simplified too due to some technical restrictions. It may not be fully compatible with some of DAW hosts due to the implementation differences of fragmented VST standard.  
       
  Q: Bad/No Effect  
  A: Calibration, calibration and calibration! This app operates as an external compander (aka: outboard compander). By default, a typical outboard compander won't perform at its best out of the box without calibration -- regardless of being analog hardware or digital software. This app is no exception. However, it comes with calibration tools and embedded guidance to assist the user to calibrate and fine-tun it in order to fit into each specific audio workflow.  
       
  Q: Other Type of NR Codecs?  
  A: Dolby-A/SR/S are likely the next ones. But unfortunately, Dolby Labs seems to be very protective in disclosing technical details to the public. So far, reverse-engineering Dolby-A seems to be possible. But S and SR are extremely opaque and hard to reproduce in software duo to luck of technical documentations.  
       
  Q: Supported File Formats?  
  A: It varies from system to system because the app employs the current system's audio file I/O programming interface for read/write audio files, which may not support all existing audio formats but may have reasonable coverage of the major popular formats, as briefly summaries below:

WAV, FLAC, AIFF: up to 96k/24bit.
MP3, AAC, M4A: up to 48k/VBR.

Please note that file extension may not always tell the actual format and sub-format in a given audio file. If the app has difficulty to open the given audio file with one of the aforementioned extensions, it may need help from other DAW app to temporarily convert to an acceptable format. Let this app focus on its codec job.

 
       
  Q: Batch Processor?  
  A: This feature was missing but starting middle of 2019, the app is able to batch process a group of files, with the following notes:
- The process will overwrite the existing files, so, copy before processing.
- No recursive traverse through subfolder tree for limiting accidental damage.
- All files in a given group will be processed by the same codec with the same parameters.
