Spectroid is a real-time audio analysis tool designed to measure sound frequencies through device microphones. It turns raw audio input into actionable data using a real-time spectrum analyzer, helping users understand noise behavior, pitch distribution, and signal balance during testing scenarios that demand accuracy rather than presentation and consistent results.

Spectroid serves professionals and hobbyists who rely on portable measurement tools. The spectrogram view allows continuous frequency tracking over time, making it useful for field diagnostics, environmental sound checks, and troubleshooting tasks where portability, clarity, and reliable readings matter most during varied testing conditions across sites.

How a mobile audio spectrum analyzer supports analysis

Spectroid focuses on capturing live sound and converting it into frequency data with minimal overhead. Through frequency range control, users can isolate specific bands, making the tool effective for identifying interference, resonances, or imbalance issues. Its processing stays responsive during sustained input, which supports longer monitoring sessions. Compared with alternatives like Audio Spectrum Monitor, the software emphasizes stability and measurement accuracy over visual styling choices.

Usability remains straightforward, allowing users to adjust sampling behavior without complex setup. The inclusion of peak detection helps identify dominant frequencies quickly, reducing guesswork during analysis. Performance remains consistent across prolonged use, with readings updating smoothly under changing sound conditions. When compared with tools such as Spectral Audio Analyzer, this solution favors dependable operation, though it offers fewer customization paths for advanced workflows in practical scenarios.

User experience centers on dependable measurement rather than decorative elements, which suits technical tasks well. With calibration support, results can align more closely with external references, improving confidence in collected data. However, the lack of advanced export options may limit deeper post-analysis. Alternatives like Advanced Spectrum Analyzer provide richer output controls, but this tool maintains an efficient balance between accuracy, portability, and everyday reliability needs.

FAQ

Q: Why are the dB values negative?

A: Spectroid uses dBFS (Full Scale) where 0 dB is the maximum power that the microphone can measure, so the decibel values are negative because the measured power is less than the maximum power.

Q: Can I zoom in on the spectrum plot?

A: Yes, do a two-finger pinch-to-zoom gesture.

Q: Why are there discontinuities/gaps in the spectrum plot and waterfall?

A: Spectroid uses multiple FFTs overlapped in frequency in order to provide better frequency resolution at lower frequencies than a single FFT. The caveat of this method is varied impulse response and minor discontinuities in frequency. The upside is that it can efficiently produce a spectrum that better matches the frequency resolution of human audio perception. It's still probably not as good as your ears though!
