Strange that in the command line version of WavePad it still prompts you for Input/Output Codec settings etc. making it difficult to automate. Is that the same in the latest version, we're using V2.01
Anyhow I stumbled across Switch V1.05 whilst trying to download the latest version of WavePad and after a little head-scratching it works great
I'll update this later and tell you how reliably it's working as it has to process 1000s of file a day on our CTI platform
