To lower the quality of your microphone, there are a few things you can try:
1. **Change the sample rate:** The sample rate is the number of samples taken per second when recording audio. A lower sample rate will result in lower quality audio. For example, if you’re currently recording at 44.1kHz, try lowering it to 22kHz or even 11kHz.
2. **Change the bit depth:** The bit depth of a recording determines the level of detail it can capture. Lowering the bit depth will reduce the quality of the recording. For example, if you’re currently recording at 16-bit, try lowering it to 8-bit.
3. **Add noise:** You can intentionally add noise to your recordings to lower their quality. This could be anything from a soft buzz to a loud hiss. There are many ways to do this, but
