Raw data to WAV format - adjusting rate 44100 - Stack …
https://stackoverflow.com/questions/12454201/raw-data-to-wav-format-adjusting-rate-44100
I'm recording audio from Microphone but when I try to encode this raw data to wav format using WaveEncoder (or any other encoder - I tried several) it generates too fast (with higher sample per sec) speech with 44100Hz. Here's a code for encoding:

Now if you assume you want to start the AA filter roll-off at 20kHz, and you allow the aliases to fold back down to 20kHz again, then the 44.1k sampling rate will allow you 2*(22.05-20)kHz = 4.1kHz roll-off range while 48kH will give you 2*(24-20)kHz = 8kHz.

I believe that what you want to do instead is to rate convert 44100 Hz to 22000 Hz, which is a ratio of 22 out of 441 . To do that you would use resample not downsample. SUCHITHRA K S on 24 Oct 2018.

Why is the standard audio sample rate 44.1 kHz? The most common audio sample rate you’ll see is 44.1 kHz, or 44,100 samples per second. This is the standard for most consumer audio, used for formats like CDs. This is not an arbitrary number. Humans can hear frequencies between 20 Hz and 20 kHz.
