Converting mp3 to wav using CLI

Am I right in thinking I won’t be able to broadcast an MP3 using the Paging and Intercom module unless I first convert it to a specific type of wave file? Is there a command line command I can run to do this? Many thanks!!

so I’ve got as far as figuring out I need to use sox? I tried to use “file convert” but that just kept saying

“cannot open”.

But I need to install sox with MP3 support.

so I tried to remove sox

[[email protected] ~]#  yum remove sox

Bit worrying where it says Package freepbx.x86_64 0:14.1-1.sng7 will be erased !!

Anyway it didn’t let me proceed.

Any ideas? Many thanks!!

use mpg123 maybe?

ffmpeg -i in.mp3 -acodec pcm_s16le -ac 1 -ar 16000 out.wav

seems to work

Hi, to convert MP3 to WAV using the command line, you can try FFmpeg. I have heard it but I never tried. I think it is complicated for me. I only have experience in conversion with VLC and Joyoshare Video Cutter. The former is totally free. The latter is an all-in-one video editor. I get it from its official Christmas Carnivals. Luckily, I also get a $100 Starbucks voucher from this Xmas event.

Hi we use lame , here is a snippet

/bin/nice /usr/bin/lame -b 16 -m m -q 9-resample $dtpath$3.wav  $dtpath$3.mp3
/bin/nice /bin/chown  asterisk:asterisk $dtpath$3.mp3
