I wanted to use this to teach the basics of acoustic phonetics. I wish it had a way to adjust the y axis from logarithmic scale, to change the direction of time flow, and remove information above, say, 5000 Hz. The font is tiny.

Good but not with all features

I like the comprehensive set of features for recorded data, but disappointed that: 1) The GUI cannot flip upside-down. I use an external mic, which requires my device to be held upside-down when not using an extension cable. 2) I have to export in order to do calibrated measurements because there is no way to calibrate the frequency response for any mic used. Works with my external measurement mic (Dayton Audio iMM-6). I normally use an RTA, but this app has enough goodies in its analyses of recordings that I might see what I can record and then analyze (that is, anything *not* requiring a calibrated mic). Thank you for including a low-ish sample rate (8000 Hz) for those of us who work with frequencies in the musical notes region. My export shows 0.977 Hz bin size, which means you are using 4096 FFT bins. However, it would be awesome to also have sample rates at 4000 and 2000 Hz so we can afford finer resolution for working with very low audio frequencies when using an external measurement mic.

I take voice lessons and this is such a good app to help examine my voice, and learn more about the technical aspects of music.

I have tried 20 plus audio analyzer, this is the best so far.

About this app

VisualAudio is an acoustic analysis tool for science and engineering applications where quantitative frequency and level data are needed. In real-time analysis mode it works as both a spectrum analyzer and decibel meter. Audio samples can also be recorded and reviewed for later analysis. Raw and analyzed data, plus uncompressed audio, can be exported via email for outside analysis.

Here are the tools offered by VisualAudio:

Live Display: Real-time frequency analysis via FFT (fast Fourier transform) can be visualized with either a power spectrum or rolling spectrogram. The time evolution of SPL (sound pressure level) is displayed, along with tools to calibrate your microphone.

Acquisition: Record audio samples at up to 48 kHz sample rates with timed acquisitions using either the built-in or an external microphone.

Data Storage: Audio samples are stored on the device, with date and time stamp for later retrieval. Recordings can be named for easy identification.

Analysis: Each sound recording can be analyzed to see the overall spectrum analysis, plus the evolution of the decibel level. Power spectrum, sound level, and raw data are displayed in graphical and report format. Also replay an audio sample to see the real-time audio spectrogram, power spectrum, and level for recorded data.

Data Export: Users can email raw or processed data in text (csv or tab-delimited) or MATLAB format. Recorded samples can also be exported as an uncompressed audio (WAV) file.

With VisualAudio, you can explore the world of sound. Visualize and analyze sounds from musical instruments and vibrational resonances. Measure overtone series and harmonics. Explore phonetics and spoken words, measure the frequency response of audio equipment, or analyze animal and bird sounds.
