I have an old bose acoustic wave radio serving as my PC speakers. Powered but not connected to the computer the speakers produce a gentle hissing. When plugged in (via a 3.5mm to RCA cable) I hear noisy static -- not pure white noise, far more annoying -- and an intermittent whine that changes pitch depending on what's going on in the computer. For example, if the processor is under greater than 30% load all the noises go away. This does not happen with headphones so I think it is some combination of noise in the computer circuits and the amp built into the radio. My question is how do I make it stop? [more inside]

At a recent lecture, I taped from the soundboard & from some microphones. I meant to record these to separate channels, but I accidentally left it in low quality mode - mono, 22khz. It sounds like video got thrown into the mix. Can I salvage the audio? [more inside]

Hi there, I am doing an honours project on the effects of boat noise on dolphin communication and my supervisor had this idea of using compression to analyse this. He basically suggested that we record dolphin vocalizations in the presence and absence of boat noise, and then compress the files and determine which compresses more (dolphin sounds with the boat noise, or dolphin sounds without the boat noise). His thinking was that less complex sounds should compress less...so he thinks that boat noise will compress less than dolphin vocalizations. Thus, if dolphin vocalizations happen to compress more in the presence of boat noise than they do without the boat noise...this would sort of imply they are "losing information" so to speak. Does this make sense? [more inside]

My recent experience at work has led me to wonder whether there is any sort of personal noise cancellation gun? I envision a device or appliance that you can point at someone obnoxious to negate them using noise cancellation technology.

Ripping a CD that has tracks that lead into each other and then converting to MP3 has presented me with a problem. When I try to play the MP3s back in order there's a slight stagger when the next track starts (not a crossfade or optional pause), where on the audio CD the transition would not be noticeable. I'd like to either eliminate this error and keep the individual MP3s or rip the CD as one big audio file and convert that to one big MP3. Advice? [specs inside] [more inside]
