Audio Test Signal Generator based on Teensy3.1
Preliminary concept testing. The basic idea is to create a test signal generator oriented towards building musical instruments and effects, mainly guitar pedals. The onboard planned features are: 1. SIN wave generator with a bunch of musical frequency presets. 2. SIN sweep generator. Sweeps through a full audio scale with different rates. 3. Two noise sources: white and pink. 4. Wav file player/looper. Wav files (16bit/44.1kHz) are stored on the SD card and played in a loop when engaged. # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # The aliasing effect heard on the sin sweep samples is a result of audio encoding. It is not present when listening to the device directly. # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # #
