Simple project for generating beeping WAV files
To generate WAV file with several beeps - each one with different frequency, it's needed to define them in config.properties file. This example of config.properties
no_of_intervals=3
sample_rate=44100
n0_duration=100
n0_freq=500
n1_duration=200
n1_freq=0
n2_duration=300
n2_freq=750
is describing sound that beeps with frequency of 500 Hz for 100 ms then is silent for 200 ms and finally beeps with frequency of 750 Hz for 300 ms.
