I ordered a hothouse a few weeks ago and I’m loving it! I’ve written an overdrive effect as my first foray into DSP and I’m really happy with how it has turned out. One thing I’ve discovered is that at the default block size of 48 and default sample rate of 48kHz there is 1kHz noise coming from the ADC. It appears that this is a known issue with the daisy seed (see https://forum.electro-smith.com/t/questions-about-digital-noise-and-grounding/) where there is noise at the frequency sampleRate/blockSize. In that other thread there are several hardware workarounds mentioned, and I’m not sure if the hothouse is using any of those, but I’ve resorted to reducing block size to 4 samples at 96kHz sample rate to move the noise up to 24kHz and out of the audible range. This is probably not an issue for most use cases, but I am boosting the input signal by up to 96 db at which point the noise becomes significant. I wanted to point this issue and my workaround out in case anyone else runs into the same problem.
