Features & Capabilities

Signal Generator is a Chrome extension that creates audio test tones. The free sine-wave generator covers 20 Hz to 20 kHz at a 48 kHz sample rate with 16-bit samples. Pro features (via in-app purchases) unlock extended waveforms and lower frequencies, stereo control, and anti-aliased options for square, sawtooth, and triangle waves.

Optional modules add white, pink, and brown noise, and adjustable frequency sweeps (linear or logarithmic). Use cases include testing speakers and headphones, balancing home theater or car audio, masking environmental noise, burning in headphones, and tuning musical instruments.

User Reviews

Users praise Audio Signal Generator as a versatile, easy-to-use tool for testing and tuning audio systems, offering tone, sweep, and pink-noise modules with precise frequency control. It’s frequently cited by professionals for car audio and studio work and touted as portable and cost-effective compared with bench gear. Common drawbacks are stability issues (blank screens, glitches, crashes), advertising interruptions, and occasional audio output failures on some devices. Despite these, many users find it essential for tuning, testing, and teaching audio concepts.

Pros

Versatile tool for testing and tuning audio systems (PA, studio, car audio) with tone tester, pink noise, and sweep generator.
Precise control and measurement (frequency in Hz, semitones and cents, left/right channel options) for accurate tuning.
User-friendly and intuitive interface with easy-to-use dials and toggles.
Portable and cost-effective, often replacing bench-top gear for field work.
Widely used by professionals (car audio installers, engineers) for thousands of installs.

Cons

Stability issues including blank screens, glitches, and crashes reported after updates.
Ads reappear or persist after paying for ad-free and add-ons.
Occasional audio output issues on certain devices (e.g., iPhone 12 Pro) or when outputting sound to peripherals.

Recent reviews

This is great for testing PA systems, individual speakers, crossovers, finding rattles/buzzes in speakers or studios or showing off your subwoofers to friends & neighbors. GET IT!!

Hey, team. I have tried a reinstall, to no avail. Menu screen is blank. Once was a great app. This year has been glitchy. Ty

Paid for ad free and sweep function. Selecting menu goes to blank screen. Ap stops functioning after this. Also ads keep appearing. Total waste of time and money…
