Mix Analyzer guide
Playback Compatibility Analysis
Make a mix that holds up everywhere - phone, earbuds, car, and club - not just on your monitors.
Why your mix vanishes on a phone
Translation is whether a mix sounds good everywhere - phone, earbuds, laptop, car, club - not just on your monitors. Here is the data that explains the most common complaint: across the tracks we analyze, about 62% of the energy sits in the bass and low mids, exactly what small speakers cannot reproduce, while only around 14% lives in the midrange that a phone or laptop actually plays. The low end you love on headphones is nearly invisible on the devices most people use - which is why the mix thins out and the vocal disappears.
Midrange share
How much energy sits where small speakers live - the part most likely to reach the listener.
Mono compatibility
Whether the mix stays full when summed to one speaker.
Speaker vs headphone
How the balance reads on small speakers versus in-ear.
Low-end control
Whether sub energy you cannot hear on small systems is eating headroom.
What we see most often in real mixes
The single biggest translation problem is where the energy lives. Most mixes are built for full-range systems and forget the small ones the audience actually uses.
The pattern in the data
- Most of the energy, around 62%, sits in the bass and low mids that phones and laptops cannot play.
- Only about 14% sits in the midrange, which is the only band small speakers really reproduce.
- That gap is why a full-sounding headphone mix turns thin and vocal-light on a phone.
- Mono compatibility is often only middling, so single-speaker devices lose level too.
Why systems sound so different
A mix is not one thing - it is a different thing on every device. Four factors move it around.
What changes
- Frequency range: a phone or laptop plays almost nothing below roughly 150-200 Hz.
- Mono summing: phones, smart speakers, and many clubs collapse stereo to one point.
- Loudness and noise: cars and gyms bury quiet detail and wide dynamics.
- Earbuds: they sit in the ear canal and exaggerate the 2-5 kHz harsh region.
How to make a mix translate
You do not need a different mix per device - you need one that respects the small ones. Most of this is about the midrange and the low end.
Problem then fix
- Vanishes on small speakers: keep vocals, snare, and hooks strong in the midrange where small drivers live.
- Bass disappears on phones: lean on the bass harmonics in the midrange so the listener still senses the low end.
- Loses punch in mono: mono the low end and check the mix summed to a single speaker.
- Harsh on earbuds: tame upper-mid buildup and sibilance around 2-5 kHz.
- Wasted headroom: high-pass inaudible sub rumble that no small system reproduces.
Check it everywhere
The fastest way to catch translation problems is to leave your monitors. Bounce rough mixes early and listen around.
A translation routine
- Play it on a phone speaker and in mono - listen for what disappears or turns harsh.
- Check earbuds, a laptop, a cheap Bluetooth speaker, and the car.
- A/B a commercial reference on the same systems, level-matched.
- Do not finish on headphones alone - they hide mono and phase problems.
What Mix Analyzer adds
You get a read on where the energy sits and how the balance leans for speakers versus headphones, so you can fix translation before release instead of after the complaints.
In every analysis
- A view of how energy is shared across the bands.
- A mono-compatibility read.
- Speaker and headphone balance feedback.
- Flags for low-end energy that will not translate.
Frequently asked questions
Why does my mix sound different in the car?
Car systems are bass-heavy and you listen in a noisy, reflective space, which exposes excess or blooming low end and buries quiet detail. That is why the car is a classic translation reference.
Why does the bass disappear on my phone?
Phone and laptop speakers physically cannot reproduce low frequencies, often little below 150-200 Hz. Lean on the bass harmonics in the midrange so the listener still senses the low end on small speakers.
How do I check mix translation?
Bounce the mix and play it on several real systems - phone speaker, earbuds, laptop, car, a cheap Bluetooth speaker - and in mono, A/B against a commercial reference at matched loudness.
Should I mix on headphones or speakers?
Use both, but do not finish on headphones alone. Headphones hide mono and phase problems and over-flatter stereo and bass, so verify on speakers and in mono.
What is mono compatibility?
Whether your stereo mix still sounds full when summed to a single channel. Out-of-phase or over-widened elements partially cancel in mono, dropping level or thinning the sound on phones, smart speakers, and club PAs.
Why is my mix harsh on earbuds but fine on monitors?
Earbuds emphasize the 2-5 kHz range right in your ear canal. Tame upper-mid buildup and sibilance so the mix stays comfortable in-ear without going dull on bigger systems.
