I watched Photosounders evolution and I compared it with other spectral editors around ( Izotope RX, SpectraLayers, Metasynth and some other free ones: Coagula, Spear etc ) and I must say now, when it reached v 1.9 that Photosounder is (finally) mature and really usable to me, because it's quite fast and it has "Live Synthesis mode - it makes any change to the image heard instantly with no interruption." and this means A LOT of FUN. This feature makes it unique ( from my knowledge ) in the world of spectral editors and I am forced to give it a 10/10.
What other features I like in Photosounder: 1) it's FAST and it boots FAST 2) it's multi-platform ( PC and Mac ) and multiprocessor 3) it has a clean and concise interface and manual ( if you know the spectral slang, there is no way to stare or get lost because everything is neat and tidy, in one screen. If you are novice, the manual and YouTube examples will guide you - that's the advantage of the a mature product, I guess :) 4) it loads and saves audio and images + you can save/stream the sound as you play/edit ( if you don't like it's operations you can load the sound as image in Photoshop or any other image editor and go wild with image filters - I do :) 5) it has layers ( now that's a must feature to build complexity ) 6) it has a lot of basic image ( that also means sound ) operations ( I still work with Photoshop for extreme experiments but default Photosounder operations and tools are enough for most of stuff ) 7) it has scripting for advanced processing and sharing some knowledge. 8) protection is a simple keyfile you copy to your app dir ( that means you can use it on as many computers you want to, once that you bought it ).
It's a modern and full-featured spectral editor like no other that does what it says and it's an inspiring spectral playgroundto create new sounds never heard before. Also - I really appreciate nowadays when a tool is not bloated ... and I hope it will never be :)
Just downloaded and installed Photosounder only to find that it is NOT a VSTi. In other words it is NOT a plug in, it is only a standalone sound processor. If you want to use it in music production you will have to export .wav, .aiff or .flac files into a Rompler or Sampler. Or if you have FL-Harmor, iZotope-Iris or something similar you can export the .bmp Image file and play it in Harmor, Iris or whatever. Just so you know and won't have misconceptions about the software as I did.
