Hi,
I'm new on this forum and quite new in the topic of teensy. For a small project I need to be able to play some short sound files. I used a WTV020 board in combination with a simple 2.5 Watt Mono Amp from Adafruit and it worked...okay. The sound module does not work that great and I get a lot of click and pop and some annoying beep noises produced by the sound module.
Now I want to take this project a step further and need the power of a teensy and I thought I might as well use it's capability to output I2S sound. Unfortunately the enclosure is not big enough for the Audio Adaptor. So my question is:
Can I use the simple SD Card Adaptor for the Teensy, read the sound files and output them via I2S to an Adafruit MAX98357A I2S Amplifier? Will this reduce the produced noise (no ground loops)? Or will it be better to use a Teensy Prop Shield in combination with the SD Card Adaptor and Output the sound via it's internal amplifier (then I could use the flash memory for short sounds which need to be played immediately?)?
Best Regards
