The HOFA IQ-Series Analyser is the perfect plugin to compare the frequency ranges of different audio tracks. For example, it‘s really easy to localize problems caused by frequency overlays.

The new generation of the IQ-Series Analyser shows – like its predecessor – the frequency range as peak, hold, RMS and energy curves. The energy curve shows the frequency range considering the time factor.

Reference curves from various styles of music are onboard and you can also create and save your own references.


In addition, innovative features like high resolution frequency analysis, simultaneous analysis of multiple live-signals in one display, continuous frequency zoom or the interaction with the IQ-Series EQ make the HOFA IQ-Series Analyser an indispensable tool for anyone who wants a capable partner for his ears.

User feedback & press reviews:

I've been looking for a precisely and reliably working analyser and found it with the IQ-Series Analyser. I wouldn't want to work without, it's in use everyday - annoying frequencies are quickly discovered and my productions sound better now.

René Schellrich

I´d like to say you scored a big hit again! The IQ-Series Analyser is just the tool that I've always wanted.
At the very first test he has unmasked one hihat, which did its mischief in the lower midrange ;-)
This will certainly be - together with the IQ-Series EQ -  my absolute standard tool.

Peter Pauliks

I bought  the IQ-Series Analyser two days ago and am impressed! The analyser is a real enrichment!

Keys | Musik und Computer

"... comes up with many helpful and previously unknown features. The analysis of frequency response and loudness in mixing and mastering is now possible at the highest level."


Professional Audio

"HOFA again shows its innovative capacity and enhances a seemingly trivial display tool with more powerful, partly unique possibilities.
Value for money: very good - outstanding"
