A big part of the cost is the studio itself. All that gear is expensive. So is acoustically treating and soundproofing the studio. All that gear also means a fairly large power draw. Then there is using studio downtime to learn new tech, the latest bit of gear. Buying new gear, planning stydio changes etc. Just like rehearsal time, gear, transport and a bunch of other costs are hidden costs to fans, bands still have to pay them.
Dek is right about costs not going up. High end studios are more expensive... and the further up the ladder you go the more people sit in the control room. One of the studios I worked with would sometimes see 3 or 4 people (Head Sound Engineer, Assistant Sound Engineer, GoFer, and a Producer, though the GoFer was usually free, working for experience) in demo studios it is more common to have a single sound engineer who is often the studio owner. Changing tech has made the assistant sound engineer role almost redundant in many studios. Even more so in this period of lower musical income. Pre-automation, in large desk studios, more hands were needed to manage faders and mutes on the desk, during mix down, with the engineers and even producer having to rehearse a mix, just like another performance. Not needed in 99.9% of studios now..
As a sound engineer, there is a more steady income from television and film. Freelancing Engineers (not bound to a specific studio) often get a mix of live, studio and film and TV? Whatever is the paying gig. Touring gives good rates, but there are periods without work and of course the inconvenience of touring.
Many studios have closed their doors and many sound engineers and producers have left the industry. Piracy and the Google and streaming/sharing site's war on the music industry has resulted in the loss of so much talent, and a lot of full-time people going part-time. Sad. It has had an impact right across all aspects of the music industry.
@richard you know I am very cautious about you using a producer, especially before choosing your songs for the project. Afterall, you have the technical and creative capability to finish songs, but you lack focus. You are too easily distracted by what is new. That new patch. Effect. Chord change or discovered melody.. You are always impatient to move forward, and possibly find the detail stage of editing less engaging and less stimulating than the exciting brainstorming stage. Combine that with not being sufficiently motivated to get across the finishing line.
Largely I think you lack confidence in what you do. You question it (which is healthy) but your lack of confidence means you are plagued by self-doubt. I think it is for this more than anything that you are looking for someone else to contribute, yes, but equally important I think you need the verification and validation that someone you believe in can give you.
Very I mportantly, it not an issue with your music. You have strong opinions about music, but when it comes to your own music, doubt robs you of self-belief. I am sure you know all this.
Part of this, in my experience, is often a degree of fear. Fear of making a statement and being judged. Fear of settling for what you have when 5 minutes more experimenting might yield that one bit that really makes that song work. Fear of carving it in stone. Sadly, in experimenting, shiny paper syndrome gets you as you discover something new and exciting and... off you go, a new song evolves, while the current song languishes, unfinished, pushed aside, cast off. After all, if you never finish, your music cannot be judged, because whatever people hear, it is not the finished article. It is a very, very common issue for songwriters. For creatives in general.
Carved in stone? We'll sort of. Songs are re-written, rearranged, re-recorded, remixed, all the time! Mistakes? So what. As long as you learn from them, all will be well.
You share songs here, where it is safe to make mistakes and learn, where issues are not perceived as "permanent". That threshold you cope with well.
That said, if you have budget and view it as chance to learn, asking for explanations, watching what is done, it could be a great (though expensive) way to learn. That will only work if you are open to learning, and can gain enough confidence from the process, the producer and the result, to overcome your fear of possibly missing that vital ingredient that will make your song perfect. Still, it remains, that for you, working with a producer might just be enough to help boost your confidence that your music, that your song, really is good enough. Certainly a good producer will help you cross that finishing line. If nothing else, it is a huge part of their job!
So for you, perhaps it is the answer. At least for one song.
You seem willing to learn from others on the boards and elsewhere, and your songs do evolve and improve. However, I can't help thinking that if you could only complete a couple of songs largely on your own, even with bits of guidance on specific issues from people you respect, the confidence you would gain would be massive. There would be no stopping you. You work at your music. You grow. You enjoy hat you do. Completing a song is an important psychological step.
Whatever you do, I am sure you will create some great finished songs (unless you choose not to finish them!) and some day soon, this dilemma will be in the rear view mirror. We will still support you and cheer you on.
