Sound Byte for macOS 10.13 and later, 64 bit, all recent macOS versions

Download Sound Byte for macOS. Version 5.1.0 Archived zip download. October 13, 2021

Please note that version 5 of Sound Byte does not have some features from previous versions, including selecting the output channel mapping, or graphical selection of cut in/out times. Please be sure to download and evaluate it before purchasing. You may need to give Sound Byte full disk access, this can be done via the Privacy tab in the macOS System Preferences.

There is a default limit in macOS limit of 256 open files. This can cause problems for Sound Byte, including crashes, if multiple racks are opened.

As a fix, you can increase the number of open files on your system by opening a terminal window and entering the following:

sudo launchctl limit maxfiles 65536 200000

You will be prompted for your account password. Your account will need to be an administrator. This changes the maximum number of open files soft limit to 65536, and the hard limit to 200000. Please be sure to use these numbers.

This change is not permanent, it will need to be re-done each time you restart your Mac. You can close the terminal window after doing this.

Windows should have QuickTime installed to utilize all of the features of Sound Byte. This does not affect Mac OS X users, as QuickTime is always available.

Sound Byte will run without QuickTime on Windows, but you need to change the setting in the Sound Byte Preferences, telling the app to not use QuickTime. Note that not all features will be available without QuickTime.

Please do not install a later version of QuickTime, as it may not correctly function on Windows 8 or 10. Do not install or update QuickTime if it is already present on your PC and Sound Byte is correctly working.
