MusicalBoard — Singers’ Tools: Pitch, Scales, Metronome, Piano & Recording

MusicalBoard is built for problem-first practice: real-time vocal pitch monitor, a vocal range test with per-note map and score, vocal scales with optional pitch feedback, online metronome, virtual piano, spectrum/level view, and a full singing recorder with export — powered by WebAssembly. On desktop, tools open as movable and resizable windows from the right sidebar; on mobile, they switch to a simple single-column flow. Core analysis stays on your device (see FAQ).

Who uses MusicalBoard?

• Singers practicing intonation without a teacher
• Vocal students wanting instant feedback between lessons
• Choir members checking pitch before rehearsal
• Songwriters testing melody before recording
• Anyone who wants to know if they're singing in tune

Why browser-based tools?

There is nothing to install or update — open the site, allow the microphone, and practice. Your session works on Windows, macOS, Linux, and many Chromebooks and tablets as long as the browser supports Web Audio. Core analysis runs locally on your device; we do not run your vocal takes through MusicalBoard's servers for processing. Recorded or uploaded audio is kept only in your browser (IndexedDB) so playback survives a refresh, has an expiry check on restore about 24 hours after the last save (saving can renew it), and can be removed with the trash icon in the recorder controls. UI preferences (sensitivity, plot ranges, monitor volume) are stored in the browser's localStorage. You still get normal web plumbing (page loads, optional ads, analytics where disclosed in our Privacy Policy), but the pitch, spectrum, and recording pipelines stay in-tab.

What you get in one dashboard

Most standalone vocal utilities ask for a download or signup. Here, pitch visualization, timing, scales, and reference tones live together in a flexible window workspace: open tools from the sidebar, move or resize each panel, and focus the layout you need without switching apps or plug-ins. For the full story behind the project, see About MusicalBoard.

Open a dedicated tool page

• Singing recorder — record, upload, and review your voice — local export (Original, MP3, WAV, OGG, M4A), plus local upload analysis (10 minutes / 50MB); no server-side audio processing.
• Vocal pitch monitor — intonation in real time — see flat/sharp, vibrato, and stability; same local pipeline as the home dashboard.
• Vocal Spectrum — vocal frequency analyzer and dynamics — mic check, breath noise, and level over time.
• Online metronome — for singing and instruments — tap tempo, meters, subdivisions; free in the browser.
• Vocal scales — every key, optional pitch feedback — interval patterns with the pitch graph when you want it.
• Vocal range test — per-note intonation map & session score — heatmap and coverage beyond a simple min/max range; replay-friendly.
• Virtual piano — start notes and hear chords in-browser — no MIDI keyboard required.
• Sight singing — match a played note, then see your cents — local piano sample, 3-second hold, no upload. Not an absolute-pitch test.
• Mic Room Diagnostics — 3-step recording quality check — noise floor, room reverb, plosive detection, and a personalised solution report.

Frequently asked questions

Does MusicalBoard work on phones and tablets?

Yes, for modern mobile browsers. The dashboard and tools are designed to run on current versions of Chrome, Firefox, Edge, and Safari, including Safari on iOS. A wired or good-quality headset mic improves results; built-in phone mics work for casual checks but may pick up more room noise.

Do I need to create an account?

No. There is no login or profile. You grant microphone access in the browser when a tool asks for it; nothing in that flow requires signing up with MusicalBoard.

Is my voice recorded or sent to your servers?

Pitch, spectrum, and recording features process audio locally in your browser using WebAssembly and Web Audio. We do not upload your microphone audio to MusicalBoard for analysis. When you record or upload a take on the Singing Recorder, the audio is cached in your browser's IndexedDB on your device so it can be played back after a refresh. The cache is checked for expiry on restore about 24 hours after its last save; saving can renew that time. Page exit attempts to persist the current bank. The trash icon removes unwanted takes. Tool preferences (volume, sensitivity, layout) are saved in the browser's localStorage. Ordinary website traffic, cookies, and third-party services (such as ads) are described in the Privacy Policy.

Which browsers are supported?

Recent Chrome, Firefox, Microsoft Edge, and Safari. Enable JavaScript and microphone permissions for the site. If something fails, try another browser or update to the latest version — Web Audio behaviour varies slightly by platform.

Is MusicalBoard free?

Yes. Core practice tools are free to use. The site may show advertising (for example through Google AdSense) to help cover hosting and development; that does not change the free access to the tools on the dashboard.

Can I export my vocal recordings?

On the singing recorder page, after you capture audio you can download it in whichever format your browser actually recorded (usually WebM, though Safari may use MP4/AAC), or as MP3, WAV, OGG, or M4A encoded locally in the browser. You can also upload an existing file for local analysis (up to 10 minutes / 50MB) and play it back with synchronized history views. Files stay on your device unless you upload them elsewhere yourself.

Is this a replacement for a vocal coach or hearing care?

No. MusicalBoard is a practice aid. It does not provide medical advice or professional voice therapy. Protect your hearing, use comfortable levels, and consult qualified teachers or clinicians when you need personalized guidance.

Who runs MusicalBoard?

It is built and maintained by an independent developer, not a company or music school. The About page explains why the project exists and what it is working toward, and the Contact page has the direct way to reach the person running it.

Why are some tools, like Auto-Tune and Vocal Isolator, different from the pitch and timing tools?

Most tools on the dashboard — the pitch monitor, scales, metronome, piano, and spectrum view — only measure or play audio locally. Auto-Tune and Vocal Isolator actually process a take: Auto-Tune runs a pitch-correction algorithm on a dry vocal, and Vocal Isolator runs a pre-trained separation model (for mixes) or a noise-reduction pass (for room noise) on your audio. Both still run entirely in the browser, but they change the file rather than just report numbers about it.
