Audio quality of camcorders and other needed featuresWhich of the camcorders out let you choose and adjust the audio

The Sony DCR-HC96 I just ordered does. As far as MP3 there are probably cost for licensing issues and processing power to do the compression on the fly. I am sure most camcorders have the processing power of a fungus nat so they can only do so much and do it in real time. There are also some limits imposed for the video format that they use. =(8) > You can change the audio format later if you want.

Note: ALL camcorders can output (DV-OUT) via firewire to a PC but not all cam's can accept a signal *from* a PC, if that is important to you to be able to transfer footage to a cam, ensure you purchase a model that is listed: "DV-OUT/IN" (Bi-directional) Show quote > thanks > lbrtchx > OK, let me reword my question a bit and you might see why I am so
interested in the audio part of camcorders not to be loosy (as MP3, mpeg2). I am not just bssing you around here ~ As part of my school work I need to record ESL students as they improve their pronunciation. it is not all about sound, but visuals are important too for the students to be able to actually "see" and "listen to" their own mistakes ~ part of the work is also to study in a somewhat mesaurable way how well they are doing. I hope/think I can use a phonemes improvement based on FFT ~ I can only use commercial stuff, but I must really see if what I need is possible ~ lbrtchx Show quote
