ffmpeg: converting audio wav stereo to mono gives bad quaity
I am trying to convert a wav stereo audio file to 8000khz mono format
The input file is of good quality but after converting to mono its quality is very bad and a background voice is getting added to it.
I used this command:ffmpeg -i input.wav -ar 8000 -ac 1 -acodec pcm_u8 output.wav
I also Tried: ffmpeg -i input.wav -ar 8000 -ac 1 -acodec pcm_u8 -af "highpass=f=200, lowpass=f=3000" output.wav
But if the same file i am converting using some tool then quality coming good. so is there something wrong with my command ?

"a background voice is getting added to it"? Where should that voice come from? What is "some tool", and how did you use that other tool? I guess it comes down to what level of quality you are expecting for an 8 KHz file… Please edit and clarify your question. Include the full, uncut command line output from your ffmpeg commands. Ideally provide a sample.

The input is likely coded PCM. Linear PCM at 8 khz can't give you good quality, hence the invention of coded PCM formats.
