Turn a voice note, a song or a recording into printable soundwave art. Pick the seconds that matter, style the wave, add the words, and download a print-ready PDF plus a transparent PNG. Free, and your audio never leaves your computer.
Nothing is uploaded. The recording is decoded in this tab and thrown away when you close it.

Example output
Soundwave prints sell for around $35 to $70 framed, and the sellers who only hand over a digital file still charge $12 to $25. The audio work behind that is genuinely small: read the samples, reduce them to a few hundred peaks, draw them as bars. What people are really paying for is not having to figure out how. This page does that part and gives you the same two files a seller would email you, at no cost and with no watermark.
This is the step that decides whether the poster looks like art or like static. A three minute song squeezed into 200 bars averages out into a flat grey block, because every loud moment cancels out every quiet one. Five to thirty seconds is the sweet spot: a spoken phrase, a laugh, the hook of a song, a heartbeat from a scan. Drag the handles over the waveform above, hit play to check you have the right moment, and let the rest of the recording go.
The PDF is sized to real paper, A1 down to A4 plus the common inch sizes, and the wave inside it is vector art, so it stays perfectly sharp whether it is printed at 8 by 10 inches or blown up to A1. The lettering is rendered at print resolution as an image rather than typed with the PDF built-in fonts, which is a deliberate trade: it means a name in Urdu, Arabic, Hindi or Chinese prints exactly as you typed it, instead of vanishing. The trade back is that the lettering is baked in at the print size you pick, so pick that size before you download rather than enlarging the file later. The PNG is a flat image for screens, mockups and print-on-demand shops, and it can be exported with a transparent background so you can drop the wave onto your own artwork.
Most print shops and photo labs take a PDF like this as it is, but four things are worth knowing before you order. It is an RGB file sized to the exact trim with no bleed area, so if your shop asks for bleed or for CMYK, tell them and they can add it in a minute. Some print-on-demand sites only accept PNG or JPG, and that is what the PNG download is for. Colours on paper are never an exact match for a backlit screen, so if you have picked an unusual paper colour, ask for a small proof before committing to a large print. And if you added a QR code, scan the printed proof yourself before ordering more, because a code that is too small or printed on a dark background will not read.
Your file is decoded in the browser, then the selected section is divided into as many slices as you asked for bars. Peak mode takes the loudest single sample in each slice, which gives the spiky, detailed look most people picture. Smooth mode takes the average energy of the slice instead, which flattens the spikes and reads calmer on a wall. Either way the result is normalised, so a quiet phone recording fills the poster just as well as a studio track, and the contrast slider lets you lift the soft parts further.
There is no upload and no account. Decoding, drawing and both exports run entirely inside this tab using your browser's own audio engine, which is why it works with the door closed on a voicemail from someone you have lost. Close the tab and nothing is left behind.
