What production tools do I use?
Right now, I run three 'critical' pieces of software. N-track 3.x, Samplitude 6.0, and Cool Edit 2000.
I do all my mixing in N-track, Mastering and some noise reduction in Samplitude, and detailed wav edits in Cool Edit. Cool Edit lets you do sample level waveform edits, which are useful if you need to correct a digital over or other transient noise.
There was a time when I had resolved in my mind to do all my mixing in Samplitude. As far as the pros say, it has one of the best sounding summing out of the bunch. Consequently, the summing is not my weakest link so I've went back to N-track about a year ago. I believe the editing in N-track is superior as well as the fader automation editing. I've since upgraded my A/d converters and still have yet to discern the quality difference between N-track and Samplitude.
I still believe Samplitude does an awesome job for the mastering process. Now when I say mastering, I'm not just speaking of the eq and limiting, I'm speaking of the stuff you need to do when putting a (multiple song) CD master together for replication.
I only use a handful of shareware plugs for 95 percent of my processing. Anwida reverb, Glassverb, Blueline compressor and delay. I have one plug which I paid for - Voxengo Elephant which I use during mastering. Well, two paid plugs - I have Autotune and use it regularly, but clients don't like to heard that I needed to tune their vocal. I have a version of Ozone 2 which the company gave me as a think you for some testing I did. I don't use it any longer. I have HarBal but mostly use it for hints when trying to fix a mix I feel needs large amount of EQ adjustment. On a good mix, Harbal can easily do more harm than good - IMO.
More about Autotune - I've used it to fix parts other than vocal. I can remember three specific instances: I had a bass guitar track supplied for a mix and it seems the guitar was completely flat to the rest of the band. There was no way to re-track the bass so I was able to bring the whole part up to pitch. I had another situation with a flute part which was flat on a few notes. I believe the instrument needed some work. I used graphic mode and tuned the offending notes. Another one was a lead guitar solo where the guy hit a few bad notes. Once again, re-tracking was extremely inconvenient, so I moved three or four notes in graphic mode.
I have a few other tricks I use. I have a freeware plug called Dyno-2 which is basically a tape saturation emulation. It works great on rhythm guitar, piano, and drums. I also use Izotope vinyl for low-fi stuff. Either I'll use the plug to degrade echo returns or even run it on vocal tracks. The trick is to just use the eq alteration of the plug. The pops and click stuff (which makes it sound like a record) seems to be a fad that has faded.
