Overview

Generate exact equal-tempered sine-wave tuning references as WAV, MP3, or FLAC files. Choose a sustained note, chromatic scale, major scale, or natural minor scale, then set the root note, octave (2–6), A4 frequency from 400 to 480 Hz, and note duration.

When to use

When you need a concert-pitch A4=440 Hz (or custom 400–480 Hz) sine tone to tune an instrument.
When you want a practice scale in major, natural minor, or chromatic order from a chosen root and octave.
When you need a click-free local reference with short fades and 50 ms gaps between scale notes.

How it works

1Select mode: sustained note, chromatic scale, major scale, or natural minor scale, plus root note and octave 2–6.
2Set A4 tuning between 400 and 480 Hz and note duration from 0.25 to 10 seconds. Each pitch uses A4 × 2^((MIDI − 69) / 12).
3Short fades are applied and scale notes are separated by 50 ms of silence so boundaries stay clear and clicks are avoided.
4Download the result as WAV, MP3, or FLAC.

Use cases

Create a two-second A4=440 Hz WAV to tune a guitar, piano, or other instrument to concert pitch.
Export a C major practice scale at A4=432 Hz as lossless FLAC for ear-training or rehearsal.
Generate a chromatic or natural minor scale at a custom A4 frequency for equal-tempered pitch reference.

Examples

1. Standard 440 Hz A4 tuning note

Instrumentalist

Background

You need a clean concert-pitch reference before a rehearsal or recording session.

Problem

Generate an exact two-second A4 sine tone at 440 Hz.

How to use

Set mode to Sustained note, root note A, octave 4, A4 tuning 440 Hz, note duration 2 seconds, and output format WAV.

mode: sustained
rootNote: A
octave: 4
tuningA4Hz: 440
noteDurationSeconds: 2
outputFormat: wav

Outcome

A two-second mono WAV file with an equal-tempered A4 reference at 440 Hz.

2. C major practice scale at A4=432 Hz

Student or teacher

Background

You want a lossless equal-tempered C major scale tuned to 432 Hz for practice.

Problem

Export C4 through C5 with half-second notes and clear gaps between pitches.

How to use

Set mode to Major scale, root note C, octave 4, A4 tuning 432 Hz, note duration 0.5 seconds, and output format FLAC.

FAQ

Which pitches can I generate?

A single sustained note, a chromatic scale, a major scale, or a natural minor scale, using any root from C through B in octaves 2–6.

How are frequencies calculated?

Every pitch follows equal temperament: A4 × 2^((MIDI − 69) / 12), with A4 set anywhere from 400 to 480 Hz (default 440).

Why is there a gap between scale notes?

A 50 ms silence plus short fades prevents clicks and makes each note boundary easy to hear.

What output formats are available?

WAV, MP3, and FLAC.

What duration can I use?

Each note can last from 0.25 to 10 seconds (default 2 seconds).
