Please check the Mac app with an antivirus before launch as it is downloaded from the developer's website, and we cannot ensure that it is safe. This free Mac app was originally developed by VertexDSP. The program lies within Audio & Video Tools, more precisely General.
From the developer:
MultiInspectorFree is a 31 band spectral analyzer designed to be used in a multitrack environment. Based on the technology of FaderWorks to handle multiple dependent instances of the same plug-in, MultiInspectorFree provides an easy way for simultaneous spectral analysis of several audio signals.
The first instance of MultiInspectorFree behaves like a standard 31 band spectral analyzer.
