Warmup, DTMF, T9, base64
Challange starts with .wav that are around 30 min long.
After playing it it sounds like old analog phones that were in used in early 2000s Something like that:
They used DTMF encoding for each key in keyboard usually 0-9 * #
To confirm that Signal spectrum can be analized to read what frequencies are used.
That can be done in Audacity by using Plot Spectrum that results in following graph:
Plot spectrum of sine.wav
After analyzing the graph peak frequencies they are
  • 697Hz
  • 770Hz
  • 852Hz
  • 941Hz
  • 1209Hz
  • 1336Hz
  • 1477Hz
That are DTMF frequencies!
DTMF stands for Dual-tone multi-frequency signaling for example pressing key 1 resulted in wavefrom something like that
The best part of it that frequencies are in hearing range because they are in 697-1633Hz range.
More info can be found in wikipedia:
To decode what key are being pressend I used following dtmf decoder from github:
That outputs log string of digits separeted with * sign

Numbers sometimes repeat, but no more than 4times. This looks like T9 dictionary
T9 is old-school way of inputing characters to mobile phones before they transformed to smartphones
nokia 3310 with t9 dict
So signle 8 is letter t
44 transorm to h
33 to e
333 to f
First four characters are the f
For making it less cumbersome to work with it I removed * characters
