How to make a QR code for your music or podcast

Someone at your gig liked the third song. They don't know what it's called, they won't remember your band's name by morning, and the merch table is three people deep. If there's a code on the poster by the door, they can have the song on their phone before they reach the street.

That's the whole job of a music QR code: turn a moment of interest into a song playing in someone's ears, with as few steps in between as possible. The same goes for a podcast flyer on a café noticeboard, or the audio guide next to a painting.

This guide covers the choices that decide whether people actually listen.

Decide what the scan should open

There are two sensible options, and the right one depends on who's scanning.

A link to Spotify, Apple Music or your podcast app. Good when your listeners already use that app and you want follows, saves and streams counted there. The downside is that not everyone has the app you picked. An Apple Music user who scans a Spotify link gets a preview and a prompt to install something, and most of them stop there.

A page that plays the audio itself. The code opens a web page with your cover art and a player, and the track starts with one tap. Nobody needs an app or an account, which matters for anyone who isn't already a fan: the person at the gig, the visitor in the museum, the parent who picked up your flyer at the school gate.

You don't have to choose only one. A hosted page can play the tracks and also show "Listen on Spotify" and "Listen on Apple Music" buttons underneath. New listeners press play, and fans follow you where they already listen. Our MP3 QR code generator builds that kind of page.

If you only want the streaming link, our page on Spotify QR codes covers that route.

Use a code you can change later

Music moves faster than print. You'll release a new single, swap the episode on the flyer, or re-record the audio guide after the exhibition changes. If the link is printed straight into the code, every change means new posters, new stickers, new sleeves.

A dynamic code prints a short link instead, and you decide where it leads from a dashboard. Put the new single on the page and the shirts you sold last year start playing it. The difference between static and dynamic codes explains how that works.

Check how long the code keeps working before you print, especially on free plans. Merch and vinyl last for years.

Get the audio file ready

People will mostly listen on mobile data, in noisy places, through phone speakers or cheap earbuds. A few small choices make a big difference.

• Use MP3. Every phone plays it. M4A (AAC) sounds a little better at the same size and also works everywhere, but MP3 is the safe default. Avoid sending people WAV files: they're about ten times bigger for no audible benefit on a phone.
• 128 to 192 kbps is plenty for music. At 128 kbps, a minute of audio is roughly 1 MB, so a four-minute song is about 4 MB.
• Speech needs much less. For a podcast or an audio guide, 64 kbps mono sounds clean and is half the size. Spoken word at 48 kbps mono fits close to an hour into 20 MB.
• Trim the silence. A long fade-in or a minute of room noise before the first word loses people. Start with the good part.
• Name your tracks properly. "Track 01 final v3.mp3" shows up on someone's lock screen. Give each track a real title.

If an episode is too long to host comfortably, put a short trailer or the best ten minutes on the page and add a button to the full episode on your podcast host.

Cover art matters more than you think

The cover is the first thing people see after they scan, and it's what shows on their lock screen while the track plays. Use a square image, at least 800 pixels wide, with the title readable at thumbnail size. Your album or episode artwork is perfect. A blurry phone photo of the stage isn't.

Where to put the code

Pick places where people have a moment to scan and a reason to care.

• Gig posters and flyers. Put the code near the date with a line like "Hear us before the show". Size it for the distance people stand from the wall: about a tenth of the scanning distance, so 10 cm for someone a metre away. The size chart has other distances.
• Merch. A hang tag or a printed label on a shirt, tote or vinyl sleeve turns every sale into a listener. Our guide to QR codes on T-shirts covers printing on fabric.
• Stickers. Cheap, easy to hand out at shows, and they end up on laptops and guitar cases where other people see them.
• Museums, galleries and walking tours. One code per exhibit with its own short recording, or one code per room with a track for each piece. Number the tracks to match the labels on the wall.
• Churches, schools and community groups. A code on the newsletter or noticeboard that plays this week's talk or the choir's recording reaches people who missed it.

Always add a few words next to the code: "Scan to listen", "Hear the new single", "Audio guide, 3 minutes". A bare code looks like a payment link or a website. Words tell people what they get.

Only upload what you have the rights to

This one is short but important. Upload your own recordings, music you have permission to share, or recordings that are in the public domain. A cover version of someone else's song needs the right licence before you put it online, even on a small page. If you're unsure, link to the track on a streaming service instead, where the licensing is handled for you.

Decide about downloads

Letting people download the files is generous, but it isn't always what you want. For a free EP, a press kit or a choir recording for members, downloads make sense. For music you sell, leave them off: people can listen on the page as often as they like, and a "Buy the album" button can sit right under the player.

See what gets played

A dynamic code counts scans, which tells you which poster or which venue brought people to the page. A good audio page goes a step further and counts plays for each track, and taps on your streaming links.

That data answers real questions. If the second song gets twice the plays of the first, maybe it should be the first track on the page. If the poster at the record shop gets more scans than the one at the venue, you know where to put next month's posters. If almost nobody taps the Spotify link but plenty press play on the page, your listeners aren't streaming-app people, and that's worth knowing too.

Give each location its own code, all pointing at the same page, and you'll see the difference within a week.

A quick checklist before you print

1. The scan opens a page that plays without an app, with streaming links as an extra. 2. The code is dynamic, so you can change the tracks later. 3. The audio is MP3, around 128 kbps for music or 64 kbps for speech. 4. Every track has a proper title, and the cover art is square and sharp. 5. There's a short line next to the code saying what people will hear. 6. The code is big enough for the distance, with clear space around it. 7. You own the rights to everything you uploaded. 8. You've scanned a printed test copy with an iPhone and an Android and pressed play on both.

If you want to try it, the MP3 QR code generator lets you upload your tracks, add your streaming links and see the page your listeners will get before anything goes to print.
