For Episode 10 of the Knobs Podcast, Simon Moro and Terry Hart change format and run a rapid-fire round of the questions every producer eventually asks. No long tangents, just honest, road-tested answers to the things people actually get stuck on.
Why Does My Mix Sound Great in the Studio but Bad in the Car?
Almost always, this is translation, not talent. A bad room lies to you: if it is scooping out the top and boosting the lows, you will compensate by cutting lows and pushing highs, and then everywhere else the mix sounds thin and brittle. There is a genuinely encouraging flip side, though.
“If you took it to the car and it was horrible, but you could hear that it was different, then it’s not you. You just need to fix your listening environment.”
The fixes are cheaper than a new room: headphone calibration, a quick room analysis with pink noise and a reference mic, and learning to trust a spectrum analyser when you know where your room misbehaves. Volume plays a sneaky role too. In a room you do not quite trust, you tend to crank it, which flatters the bass and pushes you to under-do the low end, so translation suffers before you have made a single EQ move.
What Actually Makes a Mix Sound Professional?
Both land in the same place immediately: a mix sounds professional when you do not hear it. You feel the song, not the processing. What makes a mix sound amateur is noticing the technology, the cheap mic, the harsh converters, the reverb doing the heavy lifting. Get out of the way, and it sounds finished.
Do Expensive Microphones Really Sound Better?
Not a black and white answer. An SM57 is cheap and still one of the best snare and guitar mics ever made, and it has even won vocal shootouts. There is real diminishing returns at the top, and a well-designed cheap mic can beat something many times its price. But there is a floor: a genuinely great condenser has to hit a certain price point. The takeaway is that it is less about price and more about the product, so hunt for the well-made bargains rather than chasing a price tag.
Why Do Professional Vocals Sound So Much Bigger Than Mine?
The answer nobody wants: it is the vocalist.
“It’s the voice. It’s the room. It’s the signal chain. It’s the engineering. And it starts with the vocalist.”
The voice is 100% of the source, and a singer who can emote and fill a room is doing something no microphone will replace. The proof is everywhere: the same drum kit, mics and preamps sound completely different under a better player, and a headliner blows away the support act on the same backline. It is not limited to voices, either. The same acoustic guitar sounds like a different instrument in different hands, and there is now research showing that even a pianist’s touch changes how the strings resonate, something physicists long insisted was impossible. So before you change your mic, get vocal coaching, then follow the signal flow from the source down: room, mic, preamp, converters. Start at the source and work your way along.
How Loud Should I Record?
At 24-bit, forget the old 16-bit habit of chasing minus 12. Aim for peaks somewhere around minus 20 to minus 30 dBFS, because line level sits near minus 18 and most gear, especially vintage gear, is built to work best around there. Push too far up and you lose transient response and headroom, and modern converters get murky at the extremes of their range. Vocals can run a little hotter, but the golden rule holds: leave headroom, because almost every stage before the converter was never designed to run near zero. Underneath all of this is gain structure, which is really just managing signal to noise: maximise the signal, minimise the noise. At 24-bit you have so much headroom that recording a touch conservatively still sits well above the floor, and different converters have their own sweet spots, some happiest in the middle, some built to be pushed. And please, stop sending stems that are clipped out.
Should I EQ Before or After Compression?
Both, and the reason why is the whole answer. EQ before the compressor is usually corrective: roll off the sub-80Hz rumble and tame resonances so the compressor is not reacting to energy you do not want it to hear. EQ after is tonal, shaping the sound once the dynamics are packaged up. A classic move is harsh 3kHz presence on a guitar: crank it before the compressor, let the compressor tame it, then pull it back the other side, and it sits beautifully without really having changed. The real question is not before or after, it is understanding that EQ is just frequency-dependent gain and knowing what you are trying to achieve.
What’s the Biggest Myth in Audio Production?
Past the joke answer, the real one is aimed at producers: the myth that you have to be cheap to get work. Underselling yourself does something to the psychology of the people you work with, like a builder offering to do the job for twenty dollars. When you start charging what the work is worth, people stop questioning you, and you have not changed a thing except your mindset. This is not an industry for the money-driven, but you do need rates that are sustainable, or every long day quietly becomes eight dollars an hour and a bad attitude.
Final Thoughts
The thread running through all seven answers is the same: fix the real problem, not the symptom. Translation over talent, source over gear, understanding over presets, and knowing your own worth. And the last word ties neatly back to the vocals question, because personability might matter more than raw technical skill. A pleasant engineer who makes a singer feel comfortable will capture a better performance than a technician who knows the exact mic and placement but cannot get anyone to relax.
