How to change pitch, speed and volume in your browser

A tour of every free control in Capo: the pitch dial, fine tuning, speed, volume and the A-B loop, with what each one is for.

The bar you keep missing is usually one beat

Looping a whole phrase means drilling the part you can already play. Narrow it until it fails again and the fault is a second long.

How to learn a song by ear without naming a single note

You do not need perfect pitch or theory. You need a slow loop, one string, and a way of asking the recording yes-or-no questions.

How to practise a passage faster when you hit a speed wall

Hitting the same wall daily is a sign, not a verdict. Usually the steps are too big, or you are drilling the wrong thing.

How to transpose a song to fit your vocal range

Move the song, not your voice. The hard part is not the transposition, it is keeping the singer sounding like a person.

Why slowed audio sounds underwater

Slowing a tape drops the pitch. Holding the pitch steady is a harder trick, and the artefacts it leaves have a cause.

Why two guitars a few cents apart beat against each other

That slow wobble when two players are nearly in tune is not a metaphor. It has a frequency, and you can count it.

Why Capo ships three time-stretch engines instead of one

Audio quality picks between SoundTouch, Signalsmith and Rubber Band. What each one costs you, and when to change it.

Why the pitch dial stops at twelve

A short note on a default: one octave each way, four if you ask for it, and a ceiling set by where the audio stops being usable.

Capo vs Transpose: what is different

How the two differ in DSP engine, pitch resolution, formant handling and filtering. Written by one of the two vendors.

Capo free vs Pro: what you keep after you close the tab

The free controls are not a trial. This sets out exactly where the line falls and who genuinely needs the workspace.

How to change the pitch of a YouTube video

Shift any video up or down in semitones without touching the speed, on the player you already use. Free, and nothing is uploaded.

How to change the pitch or key of a song on Spotify

The Web Player has no key control. Capo adds pitch, speed and looping to it, and to SoundCloud and Bandcamp.

How to remove vocals from a song in your browser

Pull the lead vocal down on whatever is already playing, and know in advance which songs will give way and which will not.

How to use an equalizer on YouTube (bass, mud and harshness)

Bass boost is why most people arrive. The equalizer does more, and muddy-sounding tracks are usually a headphone problem.

How to play any song at 432 Hz, and what it actually changes

The shift from A=440 to A=432 is 31.8 cents, a third of a semitone. How to apply it, and what it does not do.

How to make a slowed and reverb version of any song

The effect needs varispeed, not the normal speed control. The difference, and the settings that avoid a preset sound.

Capo keyboard shortcuts: the full list and how to rebind

Three surfaces carry shortcuts: the page itself, the popup and the workspace. This maps all of them and covers rebinding.

How to change pitch and speed from the right-click menu

Nine pitch presets and six speeds, without opening the popup. This covers what is in the menu and why volume is deliberately absent.

How to change the pitch or key of a song on Apple Music

The web player has no key control, and its audio is encrypted. Capo shifts it anyway, without downloading anything.

How to change the pitch and speed of a SoundCloud track

SoundCloud has no key control and one coarse speed setting. Capo adds semitone pitch, fine speed and an A-B loop.

How to slow down a TikTok video and keep the pitch normal

TikTok has no speed control on the web. Capo slows a clip to a quarter speed without the voice dropping.

Why most audio extensions do nothing on Spotify or Tidal

Protected streams refuse to hand their samples to page scripts. Here is why, and what has to be done differently.

Every site Capo works on, and the handful it cannot

Anything with HTML5 audio or video, plus per-site track detection on ten services. And the real limits.
