## Description

SoundForm Signal Generator is a versatile Chrome extension designed to produce various audio signals including White and Pink Noise, as well as Sine, Square, Triangle, and Ramp waves, plus Impulses. It utilizes multiple cycled buffers refreshed randomly to ensure truly random noise generation. This tool is perfect for audio testing, sound masking, and signal processing research. For users seeking more advanced features like combined signal generation and spectrum analysis, the developer recommends the AudioTool app, available on Android, featuring dB SPL, Leq, Spectrogram, and RT60 capabilities.

## Review summary

Users praise SoundForm for tone generation, flexible frequency options, and its usefulness for audio testing, with a simple UI. However, multiple reviews highlight stability and reliability problems (drops, freezes, screen-off lockups), inconsistent waveform behavior, device-specific performance, and occasional audio output issues with headphones or external mics.

### Pros

- Effective tone generation and precise frequency selection.
- Versatile for testing audio systems, RTA acoustics, speaker stress, and resonant frequencies.
- Simple, easy-to-use UI.

### Cons

- Major stability issues: audio drops or the app freezes, and some devices lock up when the screen turns off.
- Inconsistent waveform generation: sine often clicks or fails, and some waveforms don’t work reliably.
- Device compatibility varies by model, with performance—sometimes good, sometimes not—across different phones.
- Headphone jack/output issues: tone drops with headphones and some setups only recognize external microphones.
