We got some IVR rompts recorded by a professional vendor who recorded the prompt in the following format:
Audio Samle Size=16bit
Audio Samle Rate=44kHz
Since this format is not supported by cisco, I had to convert it to cisco format using Windows XP Sound Recorder.then the format is the following after conversion:
Audio Samle Size=8bit
Audio Samle Rate=8kHz
Audio format=CCITT u-law
But after conversion I noticed the change in clarity, and can hear a hissing noise while playing this prompts.
Q 1)Can I get rid of the disturbance/hissing noise by using some other player/convertor using some other utility for conversion?
Q 2)What if I ask the vendor to record again dirctly in 8kHz, 8bit mono..Will this make any difference in clarity , since ultimately the result is 8 kHZ 8 bit mono?
I want to get avoid getting back to the vendor...
