I'm trying to create a fade in and fade out for several wave files that I won't know the total time duration in seconds of. I read the manual but the example I see all looks like I need to know the...

My server threw this error Sox::Error (sox FAIL formats: no handler for file extension `mp3' ) This person (https://superuser.com/questions/421153/how-to-add-a-mp3-handler-to-sox) had a similar ...

I am trying to output the begin-timestamps of periods of silence (since there is background noise, by silence I mean a threshold) in a given audio file. Eventually, I want to split the audio file i...

How do I have to call sox to transform an 2 second audio file into being speed up so that the resulting length of the file is 1.5 seconds (75%)? Do I have to pass an argument to do pitch correction...

I've a couple of recordings where at the end of the track there's silence and the start of a new track (fraction). I tried to remove the start of the new track from the end of the file. My comman...

I found out that I can use SoX's play file.wav stat -freq to generate a table of levels against frequencies for a file. However, it seems to run in real time, i.e. takes as long to complete as ...

What does the output of play $file stat -freq mean? I recently ran the command, here's a sample of the output: $ play 44100Hz/3660/6517/3660-6517-0024.flac stat -freq 44100Hz/3660/6517/3660-6517...

I want to exchange 16kHz pcm --> 48kHz wav using sox. however, pcm file isn't applied in sox. so, I just changed pcm to raw, and then sox -r 16000 -e signed -b 16 -c 1 test.raw -r 48000 out.wav ...
