Synology Script - Convert .WAV and .AIFF to .MP3

gistfile1.txt

#!/bin/bash
# Script for Synology Task Planner!
# I use it to automatically convert my band practice recordings to .MP3 so we can listen to them instantly after rehearsal with our phones.

# For ARMv7 CPUs: Download https://johnvansickle.com/ffmpeg/releases/ffmpeg-release-amd64-static.tar.xz and unpack it, place ffpmeg executable to any share you like.
# For Intel CPUs: Don't have the link ready, but Google is your friend ;)

# Be sure to set execution/directory listing permission for the user that runs this script!

LOG_FILE="/volume1/TARGET_DRIVE/wav2mp3.log"  # Adjust here! Replace TARGET_DRIVE with the drive name
FFMPEG_CMD="/volume1/TARGET_DRIVE/ffmpeg"     # Adjust here! Replace TARGET_DRIVE with the drive name and point it to your ffmpeg executable
