[SoX-users] sox doesnt convert wav to adpcm vox correctly any more

[Thomas B. <tx...@we...>]

Hi,
I am using SOX for converting wav files to Dialogic adpcm vox files to
get telephony voice prompts. But since the latest version the quality of
the converted files are "terrible". Is the following command still
correct to convert an 44100Hz wav file to 8000Hz vox file?

sox 1031.wav -r 8000 -c 1 1031.vox vol 1.0 polyphase stat
