Use Multitrack Spectrum Analyzer to Mix Accurately

Music is all about hearing. But sometimes, it is just too difficult to hear that specific frequency that is lacking or boosting too much in your final mix. Here is where a visual application of spectrum analyzer comes into great assistance. It lets you “see” the music.

As described by Craig Anderton:

A spectrum analyzer, whether hardware or software, is a tool that can help analyze a mix, and reveal frequency or dynamics anomalies. It does this by dividing the audible frequency spectrum into hundreds or even thousands of bands (also called “windows”) using a process called Fast Fourier Transform (FFT), then displaying the level of each band in a graph or 3D display. This feedback is invaluable in training you to correlate what you hear with your ears to actual data about frequency response and amplitude.

Most sequencer or audio software come bundled with spectrum analyzer. If not, here is a free one: MultiInspectorFree by VertexDSP.

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.

MultiInspectorFree incorporates a standard third octave frequency analyzer. The center frequencies of the bands are based on the ISO 266:1997 standard (20 Hz to 20 kHz). Pink noise will appear flat in the frequency spectrum.

MultiInspectorFree supports up to 4 instances at a sample rate of 44.1 kHz.

For spectral analysis with more options you may want to take a look at MultiInspector.

MultiInspectorFree is available as a plug-in for Windows (VST only) and Mac OS X (VST and AU, both Universal Binary).
