Description
Sound Analyzer is an application for analyzing audio signals using only a mobile device. Its main function is to display frequency (Hz) and amplitude (dB) spectra in real time, but it can also be used to display changes in spectra over time (waterfall view) and to display waveforms (waveform view) at the same time. The frequency measurement accuracy of the Sound Analyzer is very high, and in a relatively low-noise environment, the measurement error is generally within 0.1 Hz. (when measured with default settings)
Main Functions - Peak frequency display function (displays the frequency [Hz] and amplitude [dB] of prominent spectral components in real time) - Change of display range by touch operation - Switchable frequency axis scale between logarithmic and linear scale - Max hold function - Waterfall view (displays spectral changes over time) - Waveform view (displays sound waveforms) - Note display mode (displays pitch in terms of A to G♯ note names and error [cents]) - Screenshot function (with timer) - No advertisements
About High Frequency Spectrum The app allows the highest frequency setting to be raised to 96 kHz, but settings above 22.05 kHz are primarily for high-performance devices, not for general-purpose devices. In most devices on the market today, data in the high frequency range above about 22 kHz is filtered out. Since it is not possible to acquire data in the removed range even with a higher setting value, it is normal for the spectrum in this range to contain only weak noise of less than -60 dB. However, depending on the model, larger noise due to filter processing may appear at certain frequencies such as 48 kHz and 96 kHz.
Recent changes: v1.16.0 ---------------- * Android 15 is now supported * Android 5.x is no longer supported v1.14.0 ---------------- * Improved formatting of peak data in Note display mode * Linear scale is now available in Note display mode * Updated privacy policy (paid version only) v1.13.2 ---------------- * Fixed an issue where the size of the waterfall view was incorrectly restored * Compliance with EU General Data Protection Regulation (GDPR) * Improved stability

Excellent. How do I make it show the intensity relative to a soundproofed room (or a very quiet place)? I find it unintuitive to have minus decibels (relative to what sound source)? Decibels should always be expressed relative to a quiet source (by convention that would have +0 dB). Update: Thanks for the reply. It makes sense now, although, one question remains: in dBFS what is the maximum level corresponding to 0 dB? Seems to me that this is device specific, or is there a standard?

Tuning car audio, just learning so far, but this app for Android is quite sensitive with only a phone microphone. I have tried a few now and this one seems to be quite accurate. I have a professional db meter and this app is very close to the real thing as well as the hz spectrum meter.

Just bought this app. Needed to buy as we were using the free version for to long. Really helped in a noise issue we are having with a local factory over the last year. Got the council to do a survey, the output from this app ... perfect match to thier mega expensive calibrated kit. Great app. Suggestion. Peak hold would be nice and log file output. Thanks for a great product. SB United Kingdom

Accurate app for frequency, for sure... spot on when I run a frequency generator to test my audio system. Seems reasonably accurate dB wise but without a configuration setup, it's only a guess... but a pretty good one, I think. Question: I paid for the pro app. I just moved to a new phone. Do I need to pay again?
