Teensy 4.1 Sound logging Data Optimization

I need help optimizing a Teensy 4.1 program that records sound in WAV format to an SD card from teensy audio board. I'm experiencing spikes in the recording, likely due to non-optimized data writing.

Key Requirements:
- Optimize continuous writing of sound data to SD card
- Reduce or eliminate recording spikes

Ideal Skills & Experience:
- Experience with Teensy microcontrollers
- Proficiency in handling SD card data writing
- Strong background in audio processing and optimization

Please provide relevant experience in your bids. Looking forward to your proposals.
