User Interface:
- The audio app will have a user interface that utilizes 3-gang starswitch for selections (000-199). Three switches: START, PAUSE (Looong selections require this),END (selection). Analog VOL control, Lo to Hi
Power:
Wall plug-in: 110V AC to 12V DC, 1 Amp
Audio File Format:
- The preferred format for the audio files is not specified, as the app should be able to play various formats such as MP3 and WAV.
Skills and Experience:
- Experience with Teensy microcontrollers and audio codecs.
- Proficiency in programming languages such as C++ or Arduino.
- Knowledge of audio file formats and playback.
- Ability to integrate hardware components like amplifiers and speakers.
