- Linux:
- DEB:
- Command line: go to the directory that contains the .deb file and type sudo apt install ./Quantum\ Audio\ Time\ Stretch-Linux-64bit-1.1.0.deb (The "./" in front of the file name is important so that apt recognizes it is a .deb file and not the name of a package).
- GUI: right-click of the .deb file, and choose "Open with GDebi Package Installer" or "Open with Software Install". You may need to install "gdebi" first.

- GUI: right-click of the .rpm file, and choose "Open with Software Install".

- RPM:
- Open a command-line and type sudo dnf remove Quantum-audio-time-stretch

Known issues
- Windows (32-bit):
- Quantum takes at most 1 GB of RAM, regardless of the available RAM.
- If less than 1 GB is available, the computer may swap.
- 1 GB of RAM is enough to transform three 192 kHz files at the maximum quality at the same time (providing at least 3 CPU cores are available); hence in practice Quantum will use much less memory.
- Linux:
- This is only for 64-bit Intel/AMD processors (x86_64 or amd64). For Linux on other processors, the "Generic (Java)" version can be used.
- The DEB / RPM packages should add an entry to the menu, however on some systems they don't.
- In that case this should be done manually using a menu editor.
- The Quantum application is installed in "/opt/Quantum-audio-time-stretch/bin". The executable file is named "Quantum Audio Time Stretch". An icon can be found in the same directory.
- There are various issues on scaled displays.
- From within Quantum, choose the menu "File", "Settings", tab "Appearance". Try the different options: sometimes some skins do not work on scaled display while others work.
- On some systems, setting the GDK_SCALE=2 environment variable helps.
- Generic (Java)
- This version is only for advanced users! If you are not comfortable with shell scripts or .bat files, do not use it.
- This version does not come with an installer.
- It requires a Java Runtime Environment (JRE) version 8 or greater (at least 11 recommended) to be installed.
- It probably requires modifying the included .sh or .bat script to launch the application.
- Please refer to the "README.txt" and "TestedSystems.html" files that are included in the download.
- There is no guarantee it will work on your system. Only limited testing has been done.
