How to make your bass audible on phone and laptop speakers

By Tongkit Leong · October 20, 2026 · 6 min read

Phone and laptop speakers cannot reproduce deep bass, so a bassline built only from low sub frequencies simply disappears. To make it audible, add harmonics with distortion, layer a brighter bass an octave up, and check your mix at low volume in the Tracks browser studio.

Why your bass vanishes on small speakers

A tiny speaker cone cannot move enough air to produce low notes. Most phone and laptop speakers roll off somewhere around 100 to 150 Hz, and a lot of bass notes sit well below that. A kick or bass that sounds huge on headphones can turn into a faint click on a phone.

This matters because plenty of people will hear your track exactly that way. If the bassline is the hook, it needs to survive the trip.

The fix is not to make the bass louder. Turning it up only pushes your mix toward clipping. The fix is to give the ear information it can actually hear.

Step 1: Hear the problem first

Export or play your song and listen on a phone speaker, then on headphones. Note which notes drop out. If the bass part is a clean low sine wave, it will likely be gone entirely on the phone.

Also try the lowest notes and the highest notes of the line separately. Higher notes usually survive, lower notes do not, and that tells you how much help the low notes need. If you have not yet checked your mix on different playback systems, mixing on headphones covers the other half of this habit.

Step 2: Add harmonics with the Drive effect

Harmonics are higher overtones stacked above a note. When a note has strong harmonics, your ear can infer the low note even if the speaker cannot play it. This is sometimes called the missing fundamental effect.

In Tracks, open the effects rack on the bass track and add Drive. It has three knobs: Drive, Tone, and Mix.

• Drive sets how hard the signal is pushed into the saturation curve. Raise it until the bass gains a gentle edge, then stop. You are after warmth, not fuzz.
• Tone is a low-pass filter on the driven signal. Turn it down if the added overtones sound harsh.
• Mix blends the driven sound with the clean one. Start around half and adjust by ear.

Because Drive is a crossfade, a low Mix keeps your solid low end while the driven part adds the audible overtones on top. For more on the sound of the other built-in effects, see chorus, phaser, and bitcrusher.

Step 3: Layer a mid-range bass

If Drive alone is not enough, duplicate the bass idea on a second track an octave higher. Use a brighter synth sound, such as a sawtooth patch from the built-in synth, and keep it lower in volume than the main bass.

The upper layer carries the note on small speakers. On a big system the sub does the heavy lifting and the layer just adds definition. Draw both parts in the piano roll so the notes and lengths match exactly.

Step 4: Make space with EQ

Harmonics live in the low mids, which is also where kick drums, guitars, and vocals compete. Use the per-track EQ to cut the muddy zone on other instruments so the bass layer is not buried. The fixing a muddy mix guide walks through this in detail.

Keep the kick and bass from fighting over the same moment, too. Locking the bassline with the kick is worth doing before you worry about speaker translation.

Step 5: Check at low volume

Turn your master volume down until the track is barely audible, then loop the loudest section. At low volume your ears lose bass sensitivity, which mimics a small speaker. If you can still follow the bassline, it will survive a phone.

Do this last, after the other changes, and adjust Drive or the layer level in small steps.

Common mistakes

• Boosting low EQ instead. Adding more at 50 Hz does nothing for a speaker that cannot play 50 Hz, and eats your headroom.
• Too much Drive. Heavy distortion buries the note under noise. Back off until the pitch is clear.
• Mixing only on headphones. Headphones flatter the low end. Always cross-check on a small speaker.

Frequently asked questions

Why can't I hear my bass on my phone?

Phone speakers are too small to reproduce frequencies below roughly 100 to 150 Hz. A bass made of low sub frequencies has almost nothing above that range, so it fades out. Adding harmonics lets the ear perceive the note anyway.

What are bass harmonics?

They are higher-pitched overtones stacked above the bass note, created by saturation or distortion. Small speakers can play them, and your brain uses them to infer the lower note.

Will adding Drive make my bass sound distorted?

Only if you push it. A small amount of Drive with a moderate Mix adds warmth and audibility without an obviously distorted sound. Use the Tone knob to soften any harshness.

Do I still need sub bass?

Yes. Sub bass sounds great on headphones, car systems, and club speakers. The goal is to keep it and add audible information on top, not to replace it.

Can I do this for free in the browser?

Yes. Tracks is free, runs in your browser, and keeps your project on your own device. The Drive effect, EQ, and synth used here are all built in.
