Voxengo SPAN Plus
As a Mixing and Mastering engineer, and also as a University professor, I have been testing different spectral analysis plugins for years. Without a doubt, Voxengo Span Plus has all the features that an audio engineer requires when performing a detailed analysis of any type of signal. Its design is very intuitive, and totally versatile.
As usual, Voxengo has been carefully behind every detail in the design of Span Plus.
I think Span Plus is my best partner when it comes to mixing or mastering!
I just want to say thank you for making amazing plugins. All of your plugins sound great, are easy to use, and offer so many features providing ease of use, but also provide deep customization. This is no small feat..especially coming from one person!
Thank you for your dedication to providing great sounding plugins.
