MultiFreqs is a spectrum analyzer that can show up to 28 tracks at once, with a conflict mode that highlights where tracks overlap in frequency.

It has an analog-style mode inspired by hardware analyzers and an FFT mode, mid/side views and per-instance colours, for about $17.02.

Best for: Mix Bus, Mastering, Sound Design. Genres: all genres.

What it does

MultiFreqs is a multitrack spectrum analyzer: put an instance on each track and see them all on one display, so frequency clashes between parts of a mix are easy to spot.

Two views: an analog view inspired by hardware spectrum analyzers, and a digital FFT view for a detailed, high-resolution readout.
Multitrack display: up to 28 tracks at once; each instance takes its track name automatically in VST3 and AAX, and the name can be changed by clicking it.
Colours: the analyzer colour can be set freely for every instance, so each part stands out.
Conflict mode: highlights the frequencies where tracks overlap, to find what is muddying the mix.
Readout options: selectable dB range, three integration times, and peak and average display with a reset.
Mid/side: shows either the sum of the stereo channels or the difference, to check the centre and the sides separately.
Light on resources: a hardware-accelerated, resizable interface and very little CPU use, even with 28 tracks, and less still with the window closed.

Version 1.1.5 fixed issues in Logic. There is no demo; instead a 15-day money-back guarantee applies.

When to use it

MultiFreqs is the low-cost pick for seeing many tracks on one analyzer and spotting masking. Compared with the free SPAN, which shows one source per instance, it overlays up to 28 tracks in their own colours and marks the clashes. Neutron 5 also has masking views, but they are tied to its own EQ and it costs far more; MultiFreqs only shows the problem and leaves the fix to you. Insight 2 is a much fuller metering suite with loudness and stereo tools, while MultiFreqs does one job, overlaid spectrums, at a fraction of the price.

Best for: spotting masking between kick and bass, or between vocals, guitars and keys, while mixing.
Genres: all.
Look elsewhere if: you want the analyzer to fix clashes for you (Trackspacer or Neutron 5), or loudness and stereo metering too (Insight 2).

What producers say

There is little independent coverage yet; the one write-up found is positive about its value.

Bobby Owsinski's Music Production Blog featured it in its New Music Gear Monday column, saying it "may be the answer to your prayers" for finding frequency conflicts, and praised the low price, the two display types and the lack of copy protection.
Note: it is a launch overview rather than a hands-on test, so it raises no criticisms.
