EQ Training - Find Frequency Peaks in a Music Mix
Purpose
Our Discriminative Frequency Training Test used band-filtered noise to ensure a training independent from any musical content. The following test puts those frequencies back in their context, and uses a short music track instead of noise.This custom track starts with an ultra-low frequency rumble layered with crystal clear chimes, followed by a conventional mix made from various "classic" pop instruments such as an electric bass, drums, percussions, electric piano, electric guitar and synthesizer strings, along with a male voiceover and female vocal line. The track covers the full audible spectrum and will be altered to emphasize a particular frequency band.
Training Files
The aim of this test is to familiarize the listener with the sound of the different frequency bands, not subtle frequency abnormalilties. To serve this purpose, the original recording has been abusively EQ'd using a massive 24dB (!) peaking filter, centered around the target frequencies, spaced one octave apart.Those who mastered our Discriminative Frequency Training Test will go straight to the blind test section. Others will listen to each octave and learn to associate it with its respective center frequency. Here are a few hints on how the different frequencies sound like:
- 30Hz : our audition's lowest limit (sub-woofer required); rumble, chest feeling.
- 61Hz : where the bottom of the bass lies.
- 125Hz : bass warmth; fundamental frequency of male voices.
- 250Hz : boxiness; fundamental frequency of female voices.
- 500Hz : low midrange; think telephone, bottom.
- 1kHz : midrange; think telephone, middle.
- 2kHz : high midrange; think telephone, top.
- 4kHz : harmonics mainly, hash, tiring; where human ears are most sensitive.
- 8kHz : brightness, air.
- 16kHz : sparkle, shimmer.

Test Files
For each column, tick the appropriate radio button. When the 10 files have all been labeled, click the "Submit" button to get your score. Reload the page as often as you want to perform new tests.
Once you have succeeded in getting 9 or higher without listening to the individual labeled files during the test, your training will have been successfully completed.
