Hi guys I am new to this forum. I wanted a bit of help on the following question I got for homework.
A sample of a women singing is recorded at a sample rate of 20,000Hz; the digital recording is then played back, but the sample rate parameter of the playback function set to 44,100Hz. How will her voice sound ? Explain whether her vowels will be understandable, and whether the song man still be recongnisable.
I was thinking of the lines of the Nyquist theorem. As the sampling rate must equal twice the highest frequency component. So roughly the highest frequency should be about 40,000Hz. But after upscaling the sampling rate the highest frequency is still the same. So this causes aliasing ? I am not sure about the vowels tho ? any help would be great !
Cheers Monica
