A chromatic bass tuner that listens through your mic and locks onto low frequencies accurately. 4-string, 5-string and Drop D tunings with per-string reference tones built in.
Low frequencies take a moment to lock. A clean pluck and a quiet room make the biggest difference.
Select 4-String for standard EADG, 5-String for BEADG, or Drop D. The target note buttons update immediately for each configuration.
Bass needs a clean, definite pluck. Let the string ring and mute the others. Avoid palm-muting or playing too softly — the detector needs the fundamental to come through clearly.
The low E and B strings have long wave periods. The detector may take a beat to lock on. Hold the note steady and wait for the display to stabilise before adjusting.
If a low string reads an octave too high, pluck slightly softer and move closer to the mic. Low-B on 5-string is the most prone to this — mute all other strings and pluck cleanly.
Standard 4-string EADG covers almost all playing. Five-string adds a low B for extended range.
| Tuning | Notes (low→high) | Used for |
|---|---|---|
| 4-String | E A D G | Standard bass — covers most music |
| 5-String | B E A D G | Extended low range, heavier styles |
| Drop D | D A D G | Rock, metal, grunge — quick power chord access |

Tuning is step one. Here is what producers and bass players reach for next.
Yes. The analysis buffer is set to 4096 samples on this page, which gives the autocorrelation enough resolution to lock onto B0 at 30.87 Hz. Pluck clearly with the other strings muted.
Very low frequencies produce strong overtones that can fool the detector. Pluck the string cleanly, mute everything else, and move slightly closer to the microphone. Playing too hard can cause the second harmonic to dominate instead of the fundamental.
No. Your laptop or phone mic will work in a reasonably quiet room. For the most reliable low-string detection, plugging your bass into an audio interface removes ambient noise from the signal path entirely.
No. The tuner runs entirely in your browser. Mic audio is processed locally and never uploaded.
