As I said, some sound cards are incapable of 44100 recording. Throw them away.

But the rate will depend on your hardware. If your hardware, (I do not think you have told us what it is ) is incapalble of 44100 then you must do resampling. Sox will do that for you. But it introduces noise. May be ok for speach from a noise cassette tape. > > (2) I need to be able to "visually" see the audio, on some form of graph - > this is needed during the "editing" phase - I need to locate noise, silence, > and breaks in the recorded "file" to determine seperate speaches, and removal > of blank areas. gcdmaster will do that for you. And allow you to play back a sample so you can see if it is noise. You can also edit the resultant toc file manually if you wish. It will not do ogg files however. It can burn them to cd but AFAIK not play them or allow you to see them. > > (3) I need to be able to work with the audio recording, multiple times. i.e. I > record a complete 90 minute tape (cassette) - played through my sound cards > LINE IN, in one pass, save it, open it later, remove dead air at beginning > and end, and break the "complete" recording down to seperate "files" - saving > these seperate files (audio). Yup. Except it does not save the separate files. Why do you want them saved? Surely what you want is to put them onto the CD. gcdmaster will save a file (.toc) which tells it exactly which area of the recording you want to put on which place on the cd. > > (4) Burn these seperate audio "files" onto a CD Audio disc, in which the order > of the audio "tracks" must be viewable, and the final CD Audio disc MUST be > able to be played in ANY cd player - computer, boom-box, component stereo, > etc... gcdmaster uses cdrdao. > > I also have been watching a thread I have in Knoppix.Net, and upon finding out > that "arts" is NOT where its at, and ALSA is - I have disabled my arts > running in Debian, and ran a alsa_init from a root console, set up configs, > or so it said, but do not know how to go any further than that.

Probably oss.
