Audio resample 11025Hz to 48000Hz with ffmpeg 其他方式

Question

I have many wav files 11025Hz 8bit and I like to resample to 48000Hz becouse I like to increase the high frequency.

I ask if ffmpeg can do it.I have found this: https://ffmpeg.org/ffmpeg-resampler.html

but It is not clear if can be useful. I ask if ffmpeg can do it with good result or I need to find other specific software.

Answer 1

ffmpeg -i yourfile.wav -osr 48000 outfile.wav
The switch -osr is for output sample rate.
