Converting .dash videos to .wav format.
To our knowledge, converting MPEG-DASH Video Files directly to WAVE Audio Files (.dash to .wav conversion) is not possible.
We are not aware of any media editing software or (online) conversion tool capable of converting .dash to .wav.
In a word, direct dash to wav conversion is not possible.
