Harmonix

If you're looking to create complex waveforms in your designs, the Harmonix Photoshop plug-in could be just what you need. It generates these waveforms by mixing harmonic frequencies together - and the best part is, all of their features will automatically scale to fit the image or selection you're working with. So, if you choose to change the image's size, you won't have to redo the entire wave configuration.

The Harmonix plug-in boasts a simple, yet elegant interface that can help you configure every aspect of your waveform with precision. You can adjust the frequency or fine-tune it, change the amplitude and phase of individual harmonic frequencies, and even adjust the width of the waveform to make sure it remains visible when you're working on high-resolution images. Plus, you have the added benefit of being able to memorize and restore your configuration with ease.

What's more, the Harmonix plug-in is completely free to use - you won't incur any hidden costs, nor will you be limited by trials or versions. You can use it to create paid artwork, and there's no requirement to give credit to the software creators. So, there's no excuse not to download and start using it today!

However, it's important to note that Harmonix is only available on the Windows platform, and it can only be integrated with certain applications such as Adobe Photoshop, Paint Shop Pro, and Corel PhotoPaint.
