Morphaweb is a free, open source, web-based application that allows you to drag-and-drop audio files into the browser, add markers and export in the correct format for the Make Noise Morphagene eurorack module. Fast, easy, free.

One of my hobbies is modular synthesis. One of the modules I use is Morphagene by Make Noise. By their own description:
The Morphagene music synthesizer module is a next generation tape and microsound music module that uses Reels, Splices and Genes to create new sounds from those that already exist. Search between the notes to find the unfound sounds.
It’s one of my favorite modules, but it can be a bit tricky to get sounds from your computer onto the Morphagene. Morphagene has an SD-card slot for storing “reel” WAV-files. The reels have to be a particular format though, and if you want to have configured your Morphagene “splices” up front, you have to download paid software.
To work around this, I have developed a free, open source, web-based app called Morphaweb. It allows you to build reels with splice markers and export them in the correct format. All without uploading anything to a server, to protect your privacy.
To use it, you simply import audio by dragging it into the app, then use the waveform editor and shortcuts to add/remove splice markers. When you’re done, you can download your reel as a Morphagene-compatible wave-file.
