You may be unto something here. I had recorded that AA menu prompts from Window's Sound Recorder. I extracted a good recording that I had made through a phone, and the format, bitrate, etc, were different. Just about the only similarity the others I had recorded was that they were all WAV files. I'm now experimenting with new prompts with different settings and I'll let you know how it goes. I'll post the final results. I'm sure I'm not the only person who has encountered this problem. Thanx.
