If you're looking for a Diktatorial Suite alternative, Cryo Mix is another good option. This AI-powered platform offers a range of tools for mixing and mastering music. It includes AI Mixing that lets you process your audio with tools like pitch correction and final mix preparation, and an AI Audio Separator that isolates individual stems from a single audio file. The mastering tool offers industry-standard quality with dynamic processing and EQ balancing, all through an intuitive interface.
Another good option is Songmastr, which uses AI to automatically master audio tracks based on a commercial reference track. You can upload your song and a reference track, and the service will adjust the RMS, frequency response, peak amplitude and stereo width to match the reference. It accepts WAV and MP3 files and offers free use for up to 7 songs per week with no registration, so it's a good option for musicians and producers who want to try it out without a big budget.
If you want a more general-purpose toolset, check out Sounds.Studio. The service offers audio stem splitting, generative song creation based on text prompts, and style transformation so you can try out different sounds and styles. Sounds.Studio is good for people who want to explore new ideas and expand their audio horizons without having to have a lot of musical knowledge or resources.
