Rather than save in wav, I halved the file size by using the following settings
- audio /audio settings
8000 sample rate
encoding Mulaw
and saved in .au
or you could type zip -9 my-zip-file.zip my-sound-file.au which will zip a file called my-sound-file.au and put it in a file called my-zip-file.zip
Hope that is working (thanks to GuestToo aka G2 for file compression advisement)
Anyone up for writing a "Voicemail" script that automates this?
