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 non-negligible advantages. App Store resolves many common problems of software distribution, as enumerated below:
- 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
Imagine if each software developer has to set up its own solution for providing the above services, the developer will be much distracted from app development, and also, the app's final price will be much higher due to the additional distribution overhead which has no contribution to the app's functionality & quality. Thus, the buyer may end up paying more for less, and the transaction may not necessarily be easier as it might seem -- think about the concern of giving credit card to a stranger, filling in forms with personal information, manually typing in the received license key and dealing with activation errors...etc.

Related question: Side-Load Possible?    Repurchase or renew?

 
       
  Q: Side-Loading Possible?  
  A: Unfortunately, installing the app on a computer without going through the App Store (aka: side-loading) 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 software distributer. Developers are encouraged to adopt the new sandbox technologies for being more "future proof" into 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 because niche needs are not negligible needs. For those individuals who have been needing such a specialized tool for years, it could make total sense, or completely the opposite for others. Some niche needs haven't been addressed for decades due to technical challenges or foreseeable negative ROI. But if someone is willing to commit, would it worth being recognized?

Related question: Too Cheap?    Repurchase or renew?

 
       
  Q: Too Cheap?  
  A: Well, inexpensive ≠ inferior quality. The app is not an impromptu product, 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 high-profile apps. Perhaps, it is a poor product in terms of profitability. But 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: Trial/demo version?  
  A: No, but sorry. This natural, logical and fair requirement can not be realized right away because staged license management costs too much overhead. It is not as simple as it looks like. That's why the centralized App Store makes sense. Once the app opts in joining the new ecosystem, it follows the Citizenship Code there and wishes the system becomes more sophisticated in serving customers.

  Q: Plugin Version?  
  A: For those who wish to integrate the same codec into DAW based workflow, a VST plugin is available. It is an optional software component for the existing users of the full desktop application and requires the desktop application installed on the same computer in order to be activated and working properly. The plugin comes with the exact same DSP codec engine as used in the full desktop application but without the fine-tuning tools so to focus on one thing per plugin. It is intended to give the existing desktop application users an additional option to use the same codec in the DAW environment. However, due to the diversity of today's DAW hosts, the plugin is being offered as a complimentary (free) and experimental prototype without guarantee. Please do not go to acquire the desktop application only for using the VST plugin.  
       
  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 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-tune it in order to easily fit into each specific audio workflow.

Please also note that the codec along with the fine-tuning tools are special audio filters that may change the amplituds of certain frequency compnonts, which require the input audio to have enough head room reserved. If the peak level of the input audio is already near digital saturation (0 dBFS), there will be no room for boosting certain frequency components or digital hard clip may occur. When processing serious audio material, please watch the meter and make sure that the peak not reaching the 0dBFS ceiling, or otherwise, the input audio's amplitude needs to be reduced before processing.<

 
       
  Q: Other Type of NR Codecs?  
  A: Dolby-A/SR/S are likely the next ones. But unfortunately, Dolby Labs seems to be quite 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 a 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 what it's specialized and good at 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.
 
       
  Q: Repurchase or renew?  
  A: No, no periodical repurchase or renewal will be required after the initial purchase. The software is distributed with perpetual license (no time limit). According to the current Store policy (both MS and Apple), it can be re-installed on the same computer, or, installed on limited number of different computers — under the same account used for making the initial purchase, there will be no repeated charge.
