Different Recording Issues.

I recorded some interviews using different platforms.  When converted to audio for analysis; some were mono with 16KHz and 69Kbps.  Others were stereo with 32Khz and 128Kbps.

 

Should I covnvert them to the same .wav with mono at 16Khz and 32Bits?

 

Will that affect the learning algorithm?

Sorry, most of my experience has been with HMM-based acoustic models - and for them, yes, they need to be same sampling rate and bits-per-sample
