MP3 specifics worth knowing
MP3 is a lossy format, and transcoding a lossy file does not restore what compression removed. Long recordings saved at 64kbps mono carry audible artefacts that transcription accuracy reflects.
That said, speech recognition is more forgiving than audio reproduction. Standard MP3 at 128kbps and above transcribes cleanly; the difference between 128 and 320kbps is not worth chasing.
Where bitrate genuinely hurts is at the low end and with variable bitrate encoding, where the encoder starves quiet passages. Voice memos exported at low bitrates are the most common casualty.
Getting a clean transcript out of your MP3s
The order that works: confirm the file is actually what you think it is, process it, then do a fast correction pass.
On that last step, the errors worth looking for are names, numbers, acronyms, and units — the things a speech model has no way to infer correctly. Those are quick to spot and quick to fix, and they are the errors that make a transcript unusable when published.
Everything else is usually fine. Resist the urge to rewrite for style; the transcript's job is accuracy, not polish.
Batch processing a folder of MP3s
Most MP3 collections are the same interview, meeting, or lecture split into parts. Transcribe them as a batch, then merge the outputs before proofreading.
Two things to check when merging: duplicated words at the boundaries where one recording stops and the next begins, and speaker labels restarting. A recording cut mid-sentence will produce a fragment that needs stitching.
Export in a format that keeps timestamps if the parts have any gaps between them, so the merged transcript stays synchronised.
Common MP3 problems
Corrupt header: the player skips the first second. Re-encoding the file fixes it, and costs nothing to try.
Silence padded in: a recorder that writes silence between words hurts accuracy. Trimming the leading and trailing silence before uploading removes it.
Very long single files: files over two hours are slower to process and easier to lose track of. Splitting on natural boundaries — a topic change, a speaker handover — makes both the processing and the review easier.
Frequently Asked Questions
What MP3 bitrates are supported?
We support all standard MP3 bitrates from 64kbps to 320kbps, including variable bit rate (VBR) encoded files. Higher bitrates generally produce better transcription accuracy.
How long does MP3 transcription take?
Most MP3 files are transcribed in 20-50% of the audio duration. A 10-minute MP3 typically takes 2-5 minutes to process.
Is there a file size limit for MP3s?
There's no strict limit, but we recommend files under 500MB for optimal upload speed. Longer recordings work fine—just ensure you have enough credits.
Can I convert MP3 to text for free?
Yes! New accounts receive 120 free credits (2 hours of transcription). No credit card required to start.
What's the accuracy for MP3 transcription?
We achieve 95%+ accuracy for clear MP3 audio in English. Accuracy depends on audio quality, background noise, and speaker clarity.
Does transcription work with compressed MP3s?
Yes, our AI handles compressed MP3 files well. However, heavily compressed audio (below 96kbps) may have slightly lower accuracy.
Can I identify different speakers in my MP3?
Yes! Our speaker diarization automatically detects and labels different speakers throughout your recording.
What export formats are available for MP3 transcripts?
Export as plain text (TXT), Markdown (MD), subtitles (SRT, VTT), tab-separated values (TSV), or JSON with full metadata.
Do you support stereo MP3 files?
Yes, both mono and stereo MP3 files work perfectly. We process all audio channels for optimal transcription.
How do credits work for MP3 transcription?
1 credit = 1 minute of audio. A 15-minute MP3 uses 15 credits. Credits never expire and unused credits roll over.
