AUSpeek3
AUSpeek3 is an AudioUnit plugin for macOS that provides text-to-speech synthesis emulating the Commodore 64 Software Automatic Mouth vocal synthesis engine. It is used within audio production hosts such as Logic Pro, GarageBand, and other AU-compatible DAWs to generate retro computerised speech sounds for music production, sound design, or nostalgic audio effects. The plugin is free and open-source, developed by Wavosaur.
AI Recommendation
1 suggestionAUSpeek3 is an AudioUnit plugin, not a standalone app — it runs only inside a host application such as Logic Pro, GarageBand, or other AU-compatible DAWs. The plugin itself is distributed directly by Wavosaur, not through the App Store or a host's plugin manager. We could not find evidence of a recent update or a confirmed native Apple Silicon build of AUSpeek3. Since this is a freely distributed, community-developed plugin and Wavosaur's own website shows no signs of recent activity, you should contact the developer directly at [email protected] to ask whether a native Apple Silicon version is planned before macOS 28 ships in September 2028. If Wavosaur does not respond or confirms they are not updating the plugin, the Intel-only version will stop launching in your host as soon as Rosetta 2 is removed. In that case, consider looking for alternative text-to-speech or speech-synthesis plugins that are actively maintained and available in native Apple Silicon builds — some DAW vendors and third-party plugin developers have released comparable tools more recently.
