Play short WAV sound effects on an ESP32 through an I2S DAC.
Mixes any number of 16-bit PCM clips and streams them to an I2S amplifier from its own background task, so playback never blocks the sketch. Clips carry their own volume and can repeat; a master gain sits on top. Sounds can be embedded in flash or read from LittleFS, FFat or SD (PSRAM needed for those); tones and melodies are generated with no file at all. Three sounds are built in and three more ship ready to include.
