Hi. I want to know if the following modifications can be done.
1) Can you design for higher sampling rates like 44kHz, 120kHz etc
2) Can you increase the storage size to 128, 256, 512, 1024 GB?
3) Can you increase it battery capacity to 10000, 15000, 20000 etc
4) The current voice recorder cannot record while charging. Can you modify design so that it records while charging
5) can you add a feature such that given start time and and end time and it records only during that period
If the manufacturer can implement these I will buy 100-1000 quantity initially followed by more
