I know this is common question but I'm trying to record stereo audio on the Teensy 4 w/Audio board and couldn't find a code that suits the task.
The Record.ino example that Paul designed works fine for mono. The modified version for recording stereo gives inconsistent results (glitches and jumps).
I'm wondering which route to take. I've read about adding RAM to the Audioshield. Another alternative seems to solder an external SD card to the T4 back pads to record in 4 bit SPI and make use of the T4 huge RAM, I suppose. Another one is to sell my T4 and get a T3.6 to use with the ready made microSoundRecorder code, which unfortunately is not yet compatible with T4. But I like the smaller size of the T4 for my project. I'm building a recorder for picking up environmental sounds for film production, based on a set of analog preamps and equalisers.
Another requirement is that the files are written in WAV.
Any suggestions please???
