What is an Online Tone Generator?
An online tone generator is a client-side audio utility designed to produce specific audio frequencies using four primary geometric waveforms: Sine, Square, Sawtooth, and Triangle. It operates via the browser-native HTML5 Web Audio API, calculating audio waveforms locally without uploading any data to external servers.
Common Applications:
- Auditory Testing: Mapping personal hearing range limits, including tracking frequency cutoff thresholds.
- Equipment Calibration: Aligning input and output levels on analog mixers, digital audio workstations (DAWs), and interface hardware.
- Room Acoustics: Detecting room resonance frequencies and acoustic standing waves by outputting continuous sine waves.

What is a Speaker Frequency Sweep?
A speaker frequency sweep plays a sliding audio pitch that shifts logarithmically between a chosen starting frequency (typically sub-bass at 20 Hz) and ending frequency (treble range up to 20,000 Hz). The sweep duration determines how fast the frequency changes.
How to Test Subwoofers & Speakers:
To test a subwoofer's bass response, set the sweep range from 20 Hz to 120 Hz. Watch for sudden volume drops or physical rattle sounds from the speaker casing, which helps diagnose physical structure defects or speaker cabinet vibrations.

How does the BPM Tap Tempo Calculator work?
Our BPM (Beats Per Minute) tapper measures the intervals between successive keystrokes or mouse clicks. It averages the last twelve tap intervals to display a stable and accurate tempo measurement. This manual counter is crucial for DJs, live musicians, and music producers trying to identify the tempo of an audio track without automated waveform detection tools.
Requires mic permission to listen to audio pitch.
Online Chromatic Tuner Pitch Tracking
This chromatic instrument tuner uses an **auto-correlation algorithm** to analyze microphone audio streams in real-time. Auto-correlation isolates the fundamental frequency of single voice or acoustic instrument pitches (like guitar, bass, or violin) by searching for repeating signal cycles in the time domain, calculating offset cents from target standard pitch scales.

Online Voice & System Audio Recorder
Our online recorder lets you capture audio directly from your microphone or record computer system sound loopbacks (e.g. video soundtracks or backing beats playing in other tabs) using browser-native APIs. The recorded streams are encoded locally into a WebM container, generating a safe, instant local download link.
