- A few days ago, I was wondering why there isn’t a plugin that lets you change the tones yourself, depending on what you need. There are also other planetary tones, but almost everywhere you only find the same frequencies like 432 Hz or 528 Hz. Then I discovered this plugin. It includes all the Solfeggio frequencies – and that’s not all. You can also freely set any frequency you want. This flexibility makes it, for me, one of the best plugins in this area. I really hope it stays free. Excellent work – I’m very satisfied!

- This is by far the most authentic and reliable 432Hz extension on Web Browser. All the others seek payment in dollars in order to use their extension. I am extremely grateful for the generosity of the Developer to keeping this free, however I would request the developer to have an option on his website where if a person on their own accord want to send any amount they feel like sending or have an option for buy me a coffee etc. Regardless, To all those who will be using this tool, they will all bless and send their best wishes to the Developer for doing this noble work. To ensure that this kind of tool is available for free is a great service to Humanity. Thanks again & God Bless for developing such an amazing extension.

- It works pretty well, music sounds better on youtube with it engaged. if you want to get the best sound, you have to also adjust the playback speed in the custom setting to coincide with the frequency. For 432 hz, select 98 speed (432 / 440). The speed should be 98.1818 for more accuracy. If the creator would add 1 or 2 decimal places for speed, I would give it 5 stars.
