The vocals are beautifully recorded, I must say - did you use soundproofing? An expensive mic?
That's good to know. Working so closely with the audio, I sometimes find it difficult to know whether it sounds good or not. It's probably due to ear (or brain) fatigue.
The following is a lot more information than you asked for but in case anyone wants the details, here you go.
I used this hand-held recorder to record dialogue and SFX. The Zoom H6 (paid $400 for it in 2012). It's a remarkable bit of recording tech. I don't know how they make these small things sound so good!
It comes with two mic capsules, the X/Y and the mid-side. I used the pictured mid-side capsule for no other reason than I thought it sounded better for dialogue. I held the recorder about 8 to 10 inches from my mouth and recorded in a rather crowded bedroom with enough reflective surfaces to mitigate a lot of the natural echo. Deidra's dialogue was recorded at her house in her bedroom facing toward a walk-in closet filled with hanging clothes which also helped to eliminate echo. I did not use a pop filter which caused me to have to fix a few plosives during the editing phase. But the audio you hear has very little processing done to it. For the most part, I just raised the volume with editing software and made spare use of dynamic filters like compression where I thought it was needed. But it was a lot of line by line volume leveling so I can't say it was done in a snap. My main goal was to make the dialogue sound like it was recorded in the same room. (I actually end up doing numerous recording sessions per episode as I tend to rewrite dialogue. Unfortunately even recording in the same friggin' room on different days can result in different sound quality.) Some lines sound obviously more echoy than others but for the most part it sounds pretty even if you don't listen too closely.
I got a little more professional for the third episode where I used my main vocal mic, the Studio Projects C1 ($199 I believe but that was 11 years ago), run through the same recorder, using a pop filter this time, and using an SE Reflection Filter, to boot. Going the extra mile like this resulted in better sound quality but interestingly only a little better.
When the dialogue pieces are edited I import them into Adobe Animate where I commence animating. That program was a helluva learning curve for me, let me tell ya. It seems really unintuitve at first but as you learn it, it starts making more sense. I had all these headaches trying to get it do what I needed it to do for the cartoon to work - foundational things like making the starfield continually loop in smooth fashion. The aliens have to look like they're traveling through space or the friggin' cartoon doesn't work!! lol. Sometimes I even had to "fool" it into doing what I wanted it to do. For example, the audio would always go out of sync with the animation at around the 2 to 3 minute mark. Well the cartoon is 7+ minutes long. Eventually though, through trial and error, I figured out that I had to create 7 to 8 approximately 1 minute long animation "capsules" within the program for the damn thing to stay in sync. These capsules (technically known as symbols in the program) play out one after the other during the animation. You'll see Smog's steering wheel occasionally jerk as the cartoon plays out. That's where one capsule transitions to the next.
I don't have any illusions about creating a successful YouTube channel. I just read that 60 hours of video are uploaded to the site every minute. Also, one of the main keys to building an audience for your channel is to post content regularly. Once a week or more is optinum. I'd have to break my back to get one of these things done in a month. So I'll make some more of these but it's going to have to be at my own pace, which I'm hoping will get faster but for now it's still a slow process.
Thanks for indulging me. If you got through all of this you deserve some sort of message board commendation.
