The concepts inside your studio
DeskBroadcast is built from a century of broadcast engineering. These are the ideas behind every knob — what they are, where they came from, and how to use them well.
Voice & dynamics
Dynamic range compression
The automatic volume control behind every broadcast voice — from 1930s transmitter limiters to the toggle in your mic chain.
Gain staging
Why where you add gain matters more than how much, and how to keep noise out of your signal path.
Microphone calibration
Setting the physical gain dial by measurement instead of guesswork — targets, noise floors, and why hotter isn't better.
Automatic gain control
How software rides your level during speech without amplifying the silence between sentences.
Parametric EQ
Shelves, bells and Q: sculpting a voice with four bands instead of thirty-one sliders.
Clipping & headroom
The one distortion you can't fix in post, and the case for leaving 12 dB on the table.
Noise & cleanup
AI noise removal
How neural networks separate a voice from a barking dog — and why classical filters never could.
Spectral noise reduction
Learning the sound of your room and subtracting it, one frequency bin at a time.
Noise gates
Closing the mic between phrases: envelopes, thresholds, hold times, and why a gate should never slam.
Mains hum
50 Hz, 60 Hz, and the harmonic ladder above them — where hum comes from and how notch filters remove it.
Click & transient suppression
Why keyboard clicks and trackpad thumps are hard to remove mid-speech, and the look-ahead trick that does it.
Measurement & digital audio
RMS & peak metering
Two numbers, two different questions: how loud it feels versus how close it is to clipping.
Spectrum analyzers
Reading an RTA: what the bars mean, and what a voice, a hum and a fan each look like.
Sample rates & 48 kHz
Nyquist, film sound, and why video calls, broadcast and DeskBroadcast all run at 48,000 samples per second.
Audio latency
Buffers, look-ahead and block sizes: where the milliseconds go between your mouth and your meeting.
Delayed auditory feedback
Why hearing your own voice 150 ms late makes you stumble — and what that means for monitoring yourself.
Video
Color grading
From film timing to live webcams: exposure, contrast, saturation and the order they should be applied in.
White balance
Color temperature, mixed lighting, and the difference between fixing color at the sensor and fixing it in software.
Background blur
Person segmentation, portrait bokeh, and the halo artifacts that separate good blur from bad.
UVC camera control
The universal protocol hiding inside USB webcams — real sensor controls no software filter can imitate.
