Hi All,

Just wanted to provide a link to a project we are working on using the LyraT 4.3 Board to Simulate Digital Music Playback From Vintage Analog Cassette and Reel to Reel Devices GitHub.

When we started this project, we quickly found out that the sample code provided didn't show much advance functionality, and certainly didn't show such functionality working together. As such, the main developer has done an excellent job showing.

• Read audio from line-in then play to line-out

• Implement seeking for both MP3 and FLAC files stored on SD card

• Make use of the esp-dsp library

• Implement http server

• Implement touch button functionality

• Allow for connecting to Bluetooth speakers (This is a work in progress)

Overall this project provides a good example of what's possible with these boards and also the limitations and hardware bugs (line-in) found. As a matter of fact, this board mirrors the functionality of the companion Desktop Java Program for most part.

In any case, I hope some of you find this code useful for your own work.
