Sound, not setup
Guitar audio tools
The tuner listens for a note and compares it with a string. These pages make sound or draw it. The tone generator holds a pitch when the room is too loud for a mic. The metronome is only time. The analyzer shows energy across frequency, or the raw waveform, and does not name chords.
Tools in this section
Guitar tone generator
A Web Audio oscillator: sine, triangle, square or saw, with the six standard open strings as presets and a free frequency. Not an amp recording.
Guitar metronome
A click with beats per bar, an accent on 1, and tap tempo. The scheduler uses the audio clock so the pulse does not drift. It does not listen for pitch.
Frequency analyzer
An FFT view of the microphone plus a waveform toggle. Open-string pitches are marked as landmarks. A strum is many peaks; a single note shows a fundamental and harmonics. Not a chord namer and not a tuner.
Why they are split
A click track with a spectrum glued on is how tools become mush. Timing wants a steady scheduler so the accent does not drift. A tone wants an oscillator you can leave running. A spectrum wants a fast drawing of bins, including the mess a strum makes. Each page does one of those and links to the others.
Still local
Web Audio runs in the browser. The generator does not upload a performance, and the analyzer does not record a file unless you later choose to. There is no amp model here: the tone is a plain waveform, useful as a reference, not as a guitar sound.
Questions
- Can I tune to the tone generator?
- Yes. Play a string preset and match it by ear when the microphone is useless. For cents, go back to the tuner.
- Does the metronome know the song?
- No. You set the tempo. It does not listen to the guitar.
