I don't know about kwave, but the little play and record things that come with sox have aweful quality. I don't know for sure why but I'd guess poor real time coding, as both bplay/brec and my own concoction rawrec/rawplay (which I will be releasing for alpha test shortly) get much better quality. sound-recorder has, according to it's own documentation, poor quality due to bad buffering. 'cat'ing from /dev/audio will probably suffer from the same problem. > When i record from the input port, i get nothing. Make sure your mixer settings are reasonable. > When i record from the mic port, it sounds horrid. The mic is probably going to sound awful without careful setting of the input gain, and pretty terrible even then. PC mics are incredibly cheezy, and they typically sit beside the computer and suck in all kinds of fan noise. This should be partly fixable with a simple ADALINE, it may well be that sound studio is doing something like that for mic recording and not bothering to tell you. > Does anyone know what the problem could be and how to > solve it?
