Uncommon words the AI might misspell — list them so they come out right.
MP3 is the most common audio format on the planet — recordings from phones, voice recorders, downloaded audio and exported podcast episodes almost always arrive as MP3. Trustample turns any of them into clean, punctuated text with word-level timestamps.
Unlike browser dictation tricks, Trustample transcribes the finished file with a dedicated speech-recognition model, so it handles long recordings, multiple voices, background noise and 16 languages without you re-recording anything.
What you do with the text is usually the real job. Podcasters convert an MP3 episode to text for show notes and a blog post; students turn recorded lectures into searchable study notes; interviewers pull exact quotes with timestamps to back them. The transcript arrives in a synced editor — click any sentence to hear that exact moment — so checking a quote against the audio takes seconds, not a re-listen.
How it works
- 1Drop your MP3 file into the upload box (or click to browse).
- 2Our AI transcribes it — usually well under a minute for typical files.
- 3Read, click any word to correct it, then export as TXT, DOCX, PDF, SRT or VTT.
Frequently Asked Questions (FAQs)
How long can my MP3 file be?
Free accounts include 60 minutes per month with MP3s up to 30 minutes long. Basic includes a 10-hour monthly pool with files up to 3 hours; Pro includes 20 hours monthly with files up to 6 hr 40 min or 2 GB.
How accurate is MP3 transcription?
On clear speech, accuracy is typically in the mid-to-high 90s percent range. Accuracy drops with heavy background noise, crosstalk or very low recording volume — and you can fix any word with one click in the editor.
Does it work for languages other than English?
Yes. Trustample supports 16 languages including Spanish, French, German, Portuguese, Chinese, Arabic and Japanese. Pick the spoken language before uploading for the best results, or leave auto-detect on.
Is my MP3 file kept private?
Yes. Files are stored encrypted, are never used to train AI models, auto-delete after 30 days, and you can delete them instantly — or enable paranoid mode to erase the file the moment transcription finishes.
Can I convert MP3 to text for free?
Yes — the free plan includes 60 minutes of transcription every month, files up to 30 minutes each, with TXT export and no credit card. It renews monthly, so a podcast habit or a weekly voice-note routine fits inside it indefinitely.
How do I transcribe an MP3 on my phone?
Open Trustample in your phone's browser, upload the MP3 from Files (iPhone) or your file manager (Android), and read the transcript in the same tab. It works as a normal mobile website — nothing to install.
Can it turn a podcast MP3 into an article?
Transcription is the first half; on paid plans the AI tools do the second — summaries, key points, and one-click drafts like a blog post grounded in the episode. Our guide on turning a podcast into a blog post walks through the whole workflow.
An honest note: Low-bitrate MP3s (below ~64 kbps, common in old voice recorders) lose consonant detail that no transcription engine can recover. The transcript will still be usable, but expect a heavier editing pass than with a modern recording.
