Voice recording to QR code
A voice you can scan — without the QR square
A QR code that plays a voice is really a link to a file somewhere. A TraceSound glyph does the same job with soundwave art drawn from the recording: the design is the code, and scanning it plays the voice.
How a voice QR code works — and where it breaks
A QR code holds a few thousand characters at most: not enough for a single second of audio. So a “voice QR code” holds a web address, and the recording lives wherever that address points — the generator’s servers, a file-sharing link, a shop’s website.
That works well for as long as the link does. It breaks when:
- the generator’s code was “dynamic” and the account or plan behind it ends;
- the file is moved or deleted, or the sharing link is switched off;
- the shop or service closes.
The code keeps scanning either way. It just leads nowhere, and nothing on the card tells you.
The other way
The design is the code
A glyph fetches its recording too, so it depends on us — and that is exactly what we put in writing.
-
No square on your design
The soundwave drawn from the voice is what the phone reads, in the style and colour you choose.
-
Kept, not rented
One payment, no plan to lapse. A share of our profits goes into the Forever Fund to keep recordings online.
-
Yours to download
The audio, and the artwork as SVG or PNG, whenever you like — so the voice is never only on our servers.
-
Hear it first
Make the glyph and scan it with your phone before you pay anything.
A voice QR code or a glyph?
| Voice QR code | TraceSound glyph | |
|---|---|---|
| What is scanned | A black-and-white square beside your design | The soundwave itself — the design is the code |
| Opening it | Any phone’s built-in camera app | The TraceSound scan page, in any phone browser |
| Where the voice lives | Wherever the generator or you put the file | With TraceSound, under a written promise |
| What keeps it working | Often a generator account or plan | One payment, and a share of our profits in the Forever Fund |
| Changing the recording later | Possible with a “dynamic” code | No — a glyph belongs to one recording; make another for a new one |
| Hear it before paying | Varies | Yes — make it and scan it first |
| Your own copy of the audio | Varies | Download it any time |
When a plain QR code is the better choice
- It has to open from the camera app, with no page to visit first.
- You will swap the recording later — a dynamic QR code can point somewhere new; a glyph belongs to one recording.
- It is long — a whole speech or a song. A glyph is priced by length and works best for a few seconds that matter.
- It only needs to last a week — an event flyer rather than a keepsake.
For a voice meant to be kept — on a card, in a frame or on skin — the glyph is made for that. Buying soundwave art that comes with a QR code? How that compares.

Where people put a voice they can scan
- Inside a card or on a gift tag — a birthday message in the sender’s own voice. Voice keepsakes.
- Beside a photo of someone you have lost — a voicemail, kept as their real voice. Memorial keepsakes.
- On skin — a tattoo that plays. The soundwave tattoo generator.
- In a frame on the wall — wedding vows, a child’s first words, a grandparent’s story.

Questions
About voice QR codes and glyphs
Can a QR code store a voice recording?
No. A QR code holds a few thousand characters at most — not enough for even a second of audio. Every “voice QR code” holds a web address, and the recording lives wherever that address points.
Do voice QR codes expire?
The code itself does not, but the link inside it can stop working: many generators make “dynamic” codes that run through their own servers, tied to an account or a plan. If that lapses, or the file is moved, the code still scans — and leads nowhere.
Is TraceSound a QR code generator?
No. TraceSound makes glyphs: soundwave art drawn from the recording, whose own shape is the code. It does the same job as a voice QR code — scan it, hear the voice — without the square.
Can people scan a glyph with their camera app?
Not the built-in camera: they open tracesound.com/scan in their phone’s browser and point it at the glyph. No app and no account. Printing a short line such as “Scan at tracesound.com/scan” beside it tells them where.
Can I put it on a card or a gift tag?
Yes. Download the artwork as an SVG or a high-resolution PNG and put it in your design. Print it at the size you will use and scan it once — very small prints are harder for a camera to read.
What does it cost?
One payment per glyph, priced by the length of the recording: 3 credits per 30 seconds, at 1 USD a credit. A 30-second message is 3 credits. No subscription and no renewal fee.
See the pricingWhat if TraceSound shuts down?
Every owner would get at least 3 months’ notice and a copy of each recording, and the collection would pass — with the Forever Fund — to a successor or an archive. You can also download the audio at any time.
