Hello, Newbie here

Im looking to record some songs onto computer, Via something like audacity(i obviously want a higher quality program, but enough of that)
Im looking for a type of amp which plugs into the computer you can use to edit the sound rather then using the computer as an amp with recording instruments straight to the computer(reason being i plan to edit, cut up tracks, remix songs, add drum loops. ect.)

Basically by myself be able to record whole songs. straight from playing them via computer.

Any help? im looking to spend at the most $300(Aus)
try ableton

great piece of software.

you could probably find it on tinterweb if you looked, as it's the next best thing to protools ( i reckon) just without the security.
