So I'm attempting to change out the preinstalled MTH audio clips in 30-2198-1 for clips that a friend recorded and wants to use instead. The clips are in the .M4a format which play fine and can load into audacity fine, my issue comes when trying to load them into the ADPCM program. Outlined below are the exact steps I've taken from start to finish.
1. Download audio clip
2. Load clip into audacity (changed sample rate to 48000 to 11025)
3. Export as RAW headerless file
4. Use program called switch audio file converter to convert from RAW to VOX
5. Used @SanDiegoMark Bat file to convert from VOX to IMA
6. Attempted to load file into ADPCM program. I used the settings in the screenshot below.
When I clicked do it, what I got was not what I was hoping for. A bunch of static. How can I fix this? Attached is what the clip should sound like and what it does sound like. @Lou1985
