On its own, no. A voice memo is useful evidence that a melody or lyric existed around a certain time, but the date your phone shows is just a file date, and file dates can change when you trim, copy, export or sync a recording. It also doesn’t show who wrote the song. To make a voice memo stronger, keep the untouched original file and timestamp it. TimeBinder® makes a fingerprint in your browser, the file stays on your device, and the Proof of Time Certificate shows that exact file existed no later than the recorded time.

What a voice memo can and can’t show
A voice memo can show that someone sang or played these notes and words, in this rough form, at some point before you shared it. That can matter if a dispute turns on whether your idea came first. It can’t show:
- Who wrote the song. Your voice on a recording shows who performed, not who composed. In a co-write, other people may have contributed.
- When it was really recorded. The “date created” or “date modified” on a phone or computer is a setting on that device, not an independent record. See date created vs date modified vs date taken.
- That the file is the original. Trimming, renaming, converting to another format or sending it through a chat app can produce a different file with different dates.
Why the date on a voice memo is weak evidence
Phones and apps record dates for their own housekeeping. Those dates may be reset when a file is copied between devices or zipped. What happens to file dates when you copy, zip or download shows how often this happens, and can a file’s date created be changed? explains how easily dates can be edited. You can see the dates your own file carries with the free file date metadata inspector.
A person challenging your recording does not have to prove it was faked. They only have to point out that the date is not independent. That’s why a record from outside your device helps.
How to make a voice memo easier to rely on
- Don’t edit the original. Make a copy to work on. Keep the first recording exactly as it came off the phone.
- Export it once (for example, as an .m4a or .wav) and don’t re-save it afterwards. Copy the exported file to your computer.
- Add the words. If you wrote lyrics, put them in a short text or PDF file. A lyric sheet timestamped alongside the audio ties the two together.
- Optional: check the file’s fingerprint with the free SHA-256 hash checker.
- Timestamp the files together. Your first Pooled TimeBind is free, with no credit card required. Save the Proof of Time Certificate next to the files.
- Then share the demo. See how to protect your music before sending.
New ideas or a better take are new files. Timestamp the versions you care about before they leave your hands. If you work in a DAW, the same routine applies to WAV stems and project files.
Where a voice memo fits with other evidence
Courts and counterparties usually look at the whole story: dated drafts, messages with collaborators, session files, a signed split sheet and the timestamp. A voice memo with a certificate is one good piece. Prove you wrote a song first sets out the wider routine, and does posting online prove you made it first? explains why a public post is not a substitute. This is general information, not legal advice.

Frequently Asked Questions
-
Is a phone voice memo enough to prove I wrote a song?
No. It can show that a recording existed, but not who wrote the song, and the date on the file is easy to change. Use it as one part of a set of dated records.
-
Does the date on a voice memo count as proof?
It’s a clue, not proof. The date is set by the device and can change when the file is edited, copied or synced. A timestamp from outside the device gives you a recorded time that doesn’t depend on your phone.
-
Should I trim the voice memo before I timestamp it?
Timestamp the original first. If you trim or edit it, you create a different file. Timestamp the edited version separately if you plan to share it.
-
Can I timestamp a voice memo and the lyrics together?
Yes. One TimeBind can hold up to 10 files, so you can include the audio, a lyric sheet and a chord chart in one record.
-
What does it cost?
Your first Pooled TimeBind is free, with no credit card required. After that, Pooled TimeBinds start from US$5, and an ASAP TimeBind is US$15. See plans and pricing
Keep the original, then record it
A TimeBind shows that this exact file existed no later than the recorded time and still matches its fingerprint. It doesn’t show authorship or ownership.
