“Uptown Funk” — Mark Ronson ft. Bruno Mars • Play 0:00–1:00

🎧 On Paper, Answer:

1. Name every sound you hear (drums, bass, guitar, horns, vocals, claps…)

2. Which sound is the LOUDEST?

3. Which sound is the QUIETEST?

4. Do any sounds come from the LEFT or RIGHT?

Someone made every one of those decisions. That person is the mixing engineer. Today, YOU become the mixing engineer.

Alguien tomó cada una de esas decisiones. Hoy, te conviertes en el ingeniero de mezcla.

I Can…

Yo Puedo…

Connection to Yesterday: Yesterday’s producers all share one secret weapon — mixing.

Conexión con ayer: Los productores de ayer comparten un arma secreta — la mezcla.

Volume Balancing

Balance de Volumen

What Is Volume Balancing?

¿Qué es el Balance de Volumen?

Drums = loudest foundation — the backbone of the beat.

Bass = weight and power underneath.

Melody = sits on top, clear but not overpowering.

Adjust with faders — slide each track’s volume until every element has its place.

Tambores = base más fuerte. Bajo = peso. Melodía = encima, clara pero no dominante. Ajusta con faders.

Think-Pair-Share: Which track in YOUR beat is too loud or too quiet?

¿Qué pista en TU ritmo está demasiado alta o baja?

Panning

Paneo — Colocación del Sonido

Placing Sounds Left & Right

Colocar Sonidos a Izquierda y Derecha

Kick drum = always CENTER (the anchor).

Hi-hats = slightly RIGHT.

Melody = slightly LEFT.

This creates WIDTH — your beat fills the whole space between the speakers instead of everything coming from the same spot.

Kick = siempre al CENTRO. Hi-hats = ligeramente a la derecha. Melodía = ligeramente a la izquierda. Esto crea AMPLITUD.

DOK 3: Why keep kick centered but spread hi-hats to the sides?

¿Por qué mantener el kick al centro pero los hi-hats a los lados?

EQ (Equalization)

Ecualización (EQ)

Sound Surgery

Cirugía del Sonido

EQ adjusts frequency — how bright or deep a sound is.

Cut the mud at 200–400 Hz — removes boominess.

Boost brightness on hi-hats — adds sparkle and clarity.

“EQ is surgery — small cuts, not big boosts.”

EQ ajusta la frecuencia. Corta el lodo a 200–400 Hz. Añade brillo a los hi-hats. “EQ es cirugía — cortes pequeños, no aumentos grandes.”

In Soundtrap: Use the 5-band Visual EQ on any track. Click the track → Effects → Equalizer. Drag the frequency bands to sculpt your sound.

En Soundtrap: Usa el EQ Visual de 5 bandas en cualquier pista. Haz clic en la pista → Efectos → Ecualizador.

Mixing Terms

Términos de Mezcla

Volume / Levels

Volumen / Niveles

The loudness of each individual track in a mix. Adjusted with faders to ensure no single element overpowers the others.

La intensidad sonora de cada pista individual. Se ajusta con faders para que ningún elemento domine a los demás.

Panning

Paneo

Placing a sound in the stereo field — left, right, or center. Creates width and space so instruments don’t clash.

Colocar un sonido en el campo estéreo — izquierda, derecha o centro. Crea amplitud y espacio.

EQ (Equalization)

Ecualización

Adjusting frequencies — boosting highs for brightness, cutting lows to remove muddiness. Like surgery for sound.

Ajustar frecuencias — aumentar agudos para brillo, cortar graves para eliminar lo turbio. Cirugía del sonido.

Stereo Field

Campo Estéreo

The full left-to-right sound space between two speakers. A wide stereo field makes a mix sound professional and immersive.

El espacio sonoro completo de izquierda a derecha entre dos altavoces. Un campo amplio suena profesional e inmersivo.
