Description: 

This audio adapter lets you easily add high-quality 16-bit, 44.1 kHz sample rate (CD quality) audio to your projects with Teensy 4.0, 4.1 (Rev D, D2). The older versions can be used with Teensy 4.0 by wires or an adaptor PCB.

All versions of the audio shield support stereo headphone and stereo line-level output, and also stereo line-level input or mono microphone input.

The Teensy Audio Library lets you use the input and output simultaneously together with a toolkit of audio processing objects, to easily create all types of sophisticated audio applications. You can play multiple sound files, create synthesized waveforms, apply effects, mix multiple streams, and output high quality audio to the headphones or line-out pins.

Teensy 4.x with Cortex-M7 provides even more DSP capability, allowing sophisticated synthesis applications to create many simultaneous "voices" or effects.

A 14 pin socket and 14 pin header can be used to make them plug together.

An optional Thumbwheel Potentiometer can be added for volume or control of an audio parameter.
