Where to start
Start with Freq Only mode. Press Play — you'll hear audio
filtered through a narrow bandpass, isolating a single frequency region. Move the reticle up or
down and click to mark where that frequency sits. Higher on the radar = higher frequency.
Once comfortable, switch to Freq + Pan. Now you also place your guess left or
right to identify which side of the stereo field the sound is panned to.
What to listen for
The bandpass filter narrows the audio to a small region, so listen for the character
of what's left — a rumble (low), a honk (mids), a hiss (high). The region bands on the radar's
left edge are your guide.
For panning, listen to the left/right balance. A fully panned signal arrives
clearly from one side; center sounds equal on both. Toggle the dry signal with
Space/D to re-orient.
Frequency reference
Bass60 – 250 HzThe fundamental rhythm and power of a song — bass guitars and drum shells. Build-up here makes a track sound bloated.
Low-Midrange250 – 500 HzWarmth and foundation for instruments and vocals. Cuts reduce "boxiness."
Midrange500 Hz – 2 kHzThe most sensitive range for human hearing — the body of most melodic instruments and vocals. Too much sounds "honky."
Upper-Midrange2 – 4 kHzAttack and punch. Helps vocals, guitars, and snares cut through a busy mix.
Presence4 – 6 kHzClarity and definition — boosting makes elements feel closer and more upfront.
Brilliance / Air6 – 16 kHz"Sparkle" and "air" — cymbals, string detail, vocal breath. Over-boosting leads to harshness.
