Constant Sampling Rate > 1000hz from Esp8266 internal ADC?

I am looking to do some sound analysis (beat detection etc) with my esp8266 and a simple microphone. I'd like to use the built in ADC.

Now unfortunately, using
Code: Select allvoid os_timer_arm(ETSTimer *ptimer, uint32_t milliseconds, bool repeat_flag);
just means that i can get a sampling rate of 1000hz (1ms maximum speed of the software timer).
So generally the questions here are:
a) is there a way to get a quicker timer to handle the reading of the adc?
b) is there a completely different way to do this?

as in your other thread: use board search
