Hi everyone
I have this little project on my mind to log ambient noise and acceleration/velocity, to find the correlation between them in a high speed train.
Essentially, I will be working with microphone, accelerometer (3-axis maybe ?) and microSD card (and also probably with RTC module).
The requirements are as follow:
I have been working with Arduino (AVR- & ARM-based) before. However, I am currently attracted to Teensy 4.0 as it offers delicious specs. It also has built-in RTC, makes it more pleasing. I am considering to buy. However,
1. Is the project is feasible with Teensy 4.0 + Audio Board rev D, by just using standard library teensyduino ? Or I need to use DMA for the ARM-based microcontroller to config what I require ?
2. Given that the number of samples per seconds and assuming two bytes per samples, high likely I need class10 microSD with high write speed isnt it ?
Thanks in advance.

The requirements are as follow:
- 40-48kSps for the microphone (mono would do - 1 channel)
- 300-500sps for each axis of the accelerometer
