Rapicorn Audio covers free and open-source music and audio software. This page explains how we choose tools, what we check before we write about them, how our browser tools treat your files, and how we handle corrections.
What counts as “free” here
“Free” covers several different arrangements, and we always say which one applies:
- Open source: the source code is published under a recognised licence such as GPL, LGPL, MIT or BSD. You can use, study and usually modify it.
- Freeware: free to use with no payment, but the code is closed and the developer sets the terms.
- Free tier or freemium: a genuinely usable free version, with some features reserved for a paid upgrade.
- Free trial or demo: time-limited or deliberately crippled. We don’t present these as free software. If we mention one, we label it as a trial.
A tool only appears in our free roundups if its core job can be done without paying.
How we pick tools
We look for software that is useful to people making or editing audio: DAWs, audio editors, plugins and instruments, notation programs, trackers, converters, and utilities.
Before a tool makes the cut, we ask:
- Is it available from an official source?
- Is it still maintained, or at least still working on current operating systems?
- Does the free version do something worthwhile on its own?
- Is the licence or usage policy published and clear?
Abandoned software isn’t automatically excluded. Some older plugins and programs still work well. When a project hasn’t been updated in years, we say so.
Inclusion is an editorial decision. If a page ever contains a sponsored or paid element, it will be labelled on that page.
Official download sources only
We only point readers to places where the developer distributes the software themselves. That means:
- The developer’s or project’s own website
- The project’s official code repository and release page
- Official app stores and package repositories where the developer publishes the tool
- Official plugin pages run by the developer
We avoid third-party download portals and mirrors, especially ones that wrap installers in their own downloaders or bundle extra software. Before referencing a download, we check that the domain actually belongs to the developer or project. If a developer offers checksums or signed installers, we mention it.
Licence and limits, stated plainly
Every write-up names the licence or terms of use and spells out what the free version won’t do. Common limits we look for:
- Track, voice or instance limits
- Export restrictions, such as capped bit depth, sample rate or file formats
- Features locked behind a paid upgrade
- Required account sign-up or online activation
- Restrictions on commercial use
- Time limits, which move a tool into the “trial” category
If the licence allows commercial use, we say so. If it doesn’t, or the terms are unclear, we say that too. We summarise licences in plain language, but our summaries aren’t legal advice. For commercial projects, read the licence text itself.
Watermarks, nags and upsells
Some free audio software makes money by getting in your way. We call this out clearly instead of burying it:
- Audio watermarks: periodic noise, dropouts or silence inserted into the output
- Nag screens: pop-ups asking you to buy or register
- In-app upsells: locked presets, sounds or features shown inside the interface
- Ads: inside the program or its installer
- Bundled offers: extra software offered during installation
- Data collection: telemetry or usage reporting, where it is documented or obvious
A tool with an upgrade prompt can still be a good recommendation. You should simply know about it before you install.
Platform support
For each tool we list where it actually runs:
- Operating systems: Windows, macOS and Linux
- macOS details: whether builds run natively on Apple Silicon or rely on Rosetta
- Linux details: how it’s packaged, for example Flatpak, AppImage, distribution packages or a source build
- Plugin formats: VST3, AU, CLAP, LV2, AAX, and whether a standalone version exists
- Architecture: 64-bit only, or 32-bit builds as well, where it matters
We separate what we’ve confirmed ourselves from what the developer claims. If we haven’t run a tool on a particular platform, the page says the information comes from the developer.
What hands-on checking involves
When we test a tool ourselves, we go through the basics a new user would hit:
- Download it from the official source.
- Install it and note anything unexpected in the installer.
- Open it and complete a simple task, such as recording, editing, loading a plugin or writing a short score.
- Export the result and listen for watermarks or quality limits.
- Check what the free version blocks.
- Uninstall it and note whether it removes itself cleanly.
We describe what we found, including the annoying parts.
No cracked software, ever
We don’t link to, host, or describe how to find cracked software, keygens, patched plugins, “free” copies of paid programs, or shared licence keys. We also won’t explain how to remove watermarks, bypass activation or unlock paid features without paying.
There are three reasons. It’s illegal. Cracked audio software is a common way to spread malware. And it takes money from developers, many of them individuals or small teams, who make the tools this site exists to cover.
If a paid program you want is out of reach, we’ll point you to its official free version if one exists, or to legitimate free alternatives that do the same job. Any cracked links sent to us will not be published.
How our browser tools handle your files
Rapicorn Audio offers browser-based audio tools. They process your files inside your browser, on your own device. Your audio is not uploaded to our servers.
Here’s what that means in practice:
- The tool’s code loads when you open the page, like any web page.
- When you choose a file, your browser reads it locally. Processing happens on your computer or phone using standard browser technology.
- The result is created on your device, and saving it downloads it from your browser to your storage.
- Closing the tab discards the working copy.
You can check this yourself. Once a tool has loaded, open your browser’s developer tools and watch the Network tab while you process a file. Your audio won’t appear in any outgoing request. You can also disconnect from the internet after the page loads and continue working.
Because everything runs locally, very large files are limited by your device’s memory and processing power. A long, high-resolution recording may be slow on an older phone. That trade-off is the reason your files stay private.
Keeping pages current
Free software changes often. Features move between free and paid tiers, licences change, platforms get dropped, and projects go quiet or come back to life. We review pages when we learn about significant changes, and each page shows when it was last checked. If a tool’s terms change in a way that affects our recommendation, we update the page rather than leaving outdated advice in place.
Corrections
We get things wrong sometimes, and we want to know when we do. If you spot an error, such as a wrong licence, a missing limitation, an outdated platform list, or a download source that no longer belongs to the developer, please get in touch through the contact details on this site.
It helps if you include:
- The page and the specific claim
- What’s wrong and what’s correct
- Where the correct information can be verified, ideally the developer’s own documentation
We check every report against official sources. When a correction changes the substance of a page, such as a licence, a price tier or a safety concern, we fix it promptly and note the correction on that page. Minor fixes like typos are corrected without a note.
Developers are welcome to contact us too. If your tool’s terms or features have changed, tell us and we’ll re-check it. Being contacted by a developer doesn’t change what we report. It means we get the facts right sooner.
