MS ADPCM Conversion causing major distortion[SOLVED]

Same issue as discussed on Mac OS forum. 2.0.3 - 10.8.4 MS ADPCM Conversion causing major distortion

I’m getting a lot of distortion when converting to WAV ADPCM.

I’m new to Audacity and have been using Creative WaveStudio (CWS) up until now so I’m not sure if I’m doing something wrong.

The ADPCM created by CWS contain no distortion.

I have included the original PCM, CWS ADPCM and Audacity ADPCM for your comparison.

Windows 7, Audacity 2.0.3. (Windows XP, Creative WaveStudio 7).

Any ideas on how to fix this? (728 KB)

So if you read did you follow the solution there (install SoX then use it as an external encoder in Audacity)?

sox -t wav - -e ms-adpcm "%f"


Thanks for pointer.

That worked and using external SOX resolved the sound distortions.
