For those looking to edit audio files, or mix and create digital music files, please consider these open source options. There are a lot of free audio editing software options out there!
Audacity is the mainstay for editing and recording, and is available for Windows, MacOS and Linux. It looks like you might even get this to install on a Chromebook. And they still offer legacy downloads that may work on very old computers.
LMMS is comparable to Audacity, but more for editing and not recording. It’s available Windows, MacOS and Linux.
GarageBand is for Apple devices only, and is a digital audio workstation, like LMMS. You can get it for your Apple computer or iOS device, but it is not available for Windows computers. If you encounter anyone offering GarageBand for PCs, beware, it is likely a scam or a virus!
WaveShop is like Audacity, but old-school. Try this one if you like the retro feel, or if you have a very old Windows computer that can’t handle newer software.
Mixxx is more for DJs and mixing together audio tracks. It works on Windows, MacOS and Linux.
I can recommend Audacity. I use it regularly.
