Easy Was To Convert File To 8 Bit Without Hiss?

[Jeffa]

I have a voiceover MP3 file that was done at 11,025 Hz, 16 bit, Mono and need to convert it to 8000 Hz, 8 bit mono so I can use it with my Dialogic card. Does anyone know an way to convert it properly so it does not sound like crap?

 

Each time I have tried, using Sound Forge and Adobe Audition 2, hiss is added so bad, I can not use the file. Without the conversion, the dialogic card plays the file in S-L-O-W motion, you know what I mean. I know going down to this lower range is problamatic, so I was curious if anyone had a good step by step solution that has worked for them.

 

Thanks

Officially we recommend converting from original source files which should have been recorded at 22kHz or 44kHz.

My problem is not the source files, they are recorded at 44KHz.

 

The problem is the conversion to 8 bit adds all the hiss. I can convert from 44 KHz to 8000 KHz easily. However, as soon as I change the file to 8 bits, the sound on the dialogic card is S-L-O-W

The .WAV sound file needs to be 8kHz. It will play 'slow' if it's more then 8kHz.
