Connecting to destination.

However, I am getting a wav file error. I have tried several audo apps to produce the correct format with success. Please recommend an application to produce the correct format. thanks, scott

Error decoding filler audio

The audio must be in one of these formats:

8 kHz 16-bit linear PCM headerless (*.l16)
8 kHz 8-bit µ-law encoded headerless (*.ul)
8 kHz 8-bit a-law encoded headerless (*.al)
8 kHz 16-bit linear PCM WAV (*.wav)
8 kHz 8-bit µ-law WAV (*.wav)
8 kHz 8-bit a-law WAV (*.wav)
MP3 (*.mp3) - Note: If the audio file is poorly encoded, the mp3 will not work.

There are a number of free online audio converters, such as this one: http://audio.online-convert.com/convert-to-wav
