A lot of sound and audio tools in one App.
Visualize sound and frequencies!
With this Sound Tools app you can visualize real-time microphone recorded sounds and its corresponding frequencies.
Main tools are:
Visualize real-time recording sound wave form and display dBFS (Decibel Full Scale) meter.
View the real-time (FFT) frequencies of the recording sound. Show the main (dominant) frequency.
Real-time audio / recorded spectrum analyzer. Measure the magnitude of an input signal versus frequency within the full frequency range of the instrument. Display frequency (Fourier) bins (buckets). In the settings one can change the number of requency bins to display.
Real-time instrument tuner; calibrate your guitar, violin, piano, and other instruments. Display the current recorded frequency in Hz and the note closest to this recorded frequency.
Play a 440 Hz A tone / note to tune your instruments.
Measure in real-time the Sound Pressure Level (SPL) on your Android. SPL is in dB(A). This Decibel measurement is A-weighted and thus adjusted for human ears.
+ One can change the sampling rates.
+ All graphics are drawn in real-time with no delays!
