What is pitch-to-MIDI conversion?

Pitch-to-MIDI conversion captures the pitch of your singing or instrumental playing and converts it into MIDI notes. The tool records your audio, analyzes the pitch frequencies, and generates a MIDI file that can be imported into any DAW or music software.

How does real-time pitch detection work?

The tool uses FFT (Fast Fourier Transform) analysis to break down your audio into individual frequencies. It identifies the dominant frequency (your pitch) and converts it to the nearest MIDI note in real-time as you sing or play.

Can I download the MIDI file?

Yes! After recording, you can immediately download the generated MIDI file (.mid format) to your computer. This file works with any DAW like Ableton, Logic, FL Studio, or any MIDI-compatible software.

What's the accuracy of the conversion?

Accuracy depends on input quality. For best results, sing or play a clear, steady tone in a quiet environment. The tool typically detects notes within ±5 cents of the target pitch, which is professional-grade accuracy.

Do I need any special equipment?

All you need is a microphone connected to your computer. The tool uses your browser's microphone access. A quality microphone helps, but even basic microphones work well for detecting pitch.

Can I adjust the tempo (BPM)?

Yes! Before downloading, you can set the BPM (tempo) and time signature. The default is 120 BPM in 4/4 time, but you can customize these to match your performance.

What if the pitch detection isn't working well?

Try adjusting the sensitivity slider, recording in a quieter environment, or singing/playing a clearer tone. Use a better quality microphone if possible. Make sure you allow microphone access in your browser.

How do I use the MIDI file in my DAW?

Download the MIDI file, then open your DAW (Ableton, Logic, FL Studio, etc.) and import it as a new MIDI clip. You can then edit, arrange, and add instruments to the melody on your DAW's virtual instruments.

How does pitch detection work?

The tool uses FFT (Fast Fourier Transform) to analyze microphone input and detect the fundamental frequency of your voice in real-time.

What frequency range can it detect?

Default range is 60-2000 Hz, covering most vocal ranges from male bass to female soprano plus higher instruments.

Can I use it with any microphone?

Yes! Works with laptop built-in microphones, USB headsets, phone microphones, and professional condenser mics.

What's vibrato detection?

Vibrato is a periodic variation in pitch. The tool detects vibrato rate (Hz) and width (cents) for vocal analysis.

How accurate is the pitch detection?

Typically ±1-2 semitones with FFT algorithm. Auto-Correlation method offers higher accuracy for sustained tones.

What's the cents offset?

Cents measure pitch deviation within a semitone. ±50 cents = one semitone. Helps tune singing to exact pitch.

Can I record my singing?

Yes! Click Record to capture your pitch over time, then review, analyze, or export the session.

How is pitch stability measured?

Stability score (0-100%) measures how consistently you maintain pitch. Higher = steadier singing.

Can I compare sessions over time?

Yes! Record multiple sessions and export data to track pitch accuracy improvement over time.

What does confidence score mean?

Confidence (0-100%) indicates detection reliability. High score = clear pitch signal. Low score = noisy environment.

Privacy Policy

Last updated: August 19, 2026

This Privacy Policy explains how PitchDetector.com handles information when you visit our website, use our browser-based music and audio tools, contact us, or interact with other features available through the site.

We aim to describe our practices clearly and avoid broad privacy claims that could be misleading. Different types of information may be handled differently, so this policy distinguishes between microphone or audio-tool data, ordinary website data, cookies, analytics, and information you choose to send us.

For a more technical explanation of microphone access and browser-based audio processing, please read our Data Security & Audio Privacy page.

Information We May Collect

The information associated with your use of PitchDetector.com depends on how you interact with the site.

Information You Provide to Us

If you contact us by email or through another support or contact method, you may voluntarily provide information such as:

your name;
email address;
the contents of your message;
screenshots or attachments;
browser or device information;
details about a technical problem;
feedback, correction requests, or partnership inquiries;
any other information you choose to include.

We use this information primarily to respond to your request, investigate reported problems, improve the site, maintain necessary records, and protect against misuse.

Please avoid sending sensitive personal information that is not necessary for us to address your request.

Technical and Website Usage Information

Like most websites, PitchDetector.com and the services that support it may process technical information when pages are requested.

Depending on our current website configuration and service providers, this information may include:

IP address;
browser type and version;
device type;
operating system;
referring page or source;
pages requested;
date and time of requests;
approximate geographic information;
security or error information;
basic interaction and performance data.

Some of this information may be processed automatically by hosting, content-delivery, security, analytics, advertising, or other website-service providers.

We use technical data where appropriate to operate the website, understand performance, investigate errors, protect the service, and improve the user experience.

Microphone Audio and Pitch Analysis

Some PitchDetector.com tools request microphone access so they can analyze a live voice, instrument, or other sound.

Microphone access is controlled by your browser. PitchDetector.com cannot access your microphone through these features unless the browser grants access following your action or an existing permission setting.

For supported browser-based pitch-analysis features, audio may be processed locally in the browser to estimate values such as:

musical note;
frequency in hertz;
tuning deviation;
pitch stability;
related analysis results.

Where a feature is designed to perform its pitch calculation locally, we do not intentionally store raw microphone recordings on our servers as part of that calculation.

However, local audio processing should not be confused with the broader operation of the website. Ordinary page resources, analytics, advertising, security systems, or other services may still involve normal network requests while a tool is open.

Please see our Data Security & Audio Privacy page for more detail about this distinction.

Audio Files

Some tools on PitchDetector.com may allow you to select an audio file for analysis.

Audio-file handling can vary depending on the specific feature, browser, and implementation.

Where a tool analyzes a selected file locally in the browser, the file does not need to be submitted to a remote server solely to calculate the pitch. If a future feature requires server-side processing or different handling, the relevant tool documentation and this Privacy Policy should be updated accordingly.

We do not use this policy to guarantee identical handling for every future audio feature.

Before using a file-based tool, review any tool-specific information shown on that page.

Tool Results and Preferences

PitchDetector.com tools may generate results such as:

detected note;
frequency;
cents difference;
tuning feedback;
confidence or signal-quality information.

Some tools may also offer preferences such as:

A4 tuning reference;
notation system;
sensitivity;
interface settings.

Depending on the feature, non-audio preferences may be stored locally in your browser using technologies such as local storage or similar browser storage.

Local preferences are different from raw microphone recordings.

If a specific tool stores results or preferences in another way, its documentation should describe that behavior.

How We Use Information

We may use information processed through PitchDetector.com for purposes such as:

providing and operating the website;
responding to support or contact requests;
diagnosing technical problems;
improving site functionality and usability;
understanding general site usage;
detecting abuse or security threats;
maintaining website security;
complying with legal obligations;
administering advertising or affiliate relationships where applicable;
maintaining records reasonably necessary for business or legal purposes.

We do not treat raw microphone audio as an advertising profile simply because microphone access is used for pitch analysis.

Any advertising, analytics, or other third-party processing is separate from the mathematical process used to estimate pitch.

establish, exercise, or defend legal claims.

If ownership or operation of PitchDetector.com changes through a business transaction, relevant information may be transferred as part of that transaction subject to applicable law.

We do not want phrases such as “we never share information” to create a misleading impression when normal service providers may necessarily process limited information on our behalf.

External Websites and Social Media

PitchDetector.com may link to websites or services operated by other organizations.

For example, you may choose to visit our Facebook page or follow links to external research, products, or resources.

Once you interact with a third-party website or service, that organization’s privacy practices apply to its processing of your information.

PitchDetector.com does not control the privacy practices of independent third-party websites.

We encourage users to review relevant privacy information before submitting personal information to another service.

Data Retention

We aim to retain information only for as long as reasonably necessary for the purpose for which it was collected, subject to legitimate operational, security, recordkeeping, or legal requirements.

Retention periods may vary depending on the type of information.

Support and Contact Communications

Messages sent to support@pitchdetector.com may be retained for as long as reasonably necessary to:

respond to the request;
investigate a problem;
maintain support records;
