VisualAudio Real Time audio spectrum Analyzer
Description
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.
Will a new version be released?

Great app and thanks so much for making it free! I would really like to control the time scrolling rate. It is fine for slow sounds, but I would like to have a 2 sec time axis. Thanks
Fix data export

This app used to work splendidly, but data export no longer works. I paid a $5 price tag to be able to use this capability, and it’s the main draw of the app. A good way around this would be an option to trace the power spectrum data in-app, or zoom in further to pull out details from a power spectrum graph. The review should be an easy 4/5 or 5/5, but I can’t positively review an app with such a critical error.
Long loved app now hated

Have activated email but app crashes when used. Please fix or return the in app purchase.
Was a great tool....

But is not working in iOS 12.
Fantastic spectrum analyzer

This app author seriously knocked this one out of the park. Great app!
Free App As Good As Paid

Fantastic audio toolkit!

This app packs so many great tools into one app! Real time spectrogram and other frequency analysis tools, plus the ability to record measurements for later analysis (also included in the app). Purchase allows these saved records to be shared outside the app. Very nicely done!
Great audio analyzer!

Quantitative frequency and level data with export. Real time spectrogram nice!
