Tips for Better Results
- Use a clear MP3 export instead of a heavily compressed file when possible.
- Keep files under 30 minutes for smoother browser performance.
- Trim long silence before uploading to reduce processing time.
- Use headphones or a close microphone when recording future MP3 files.
Why use SuperTextHub?
Files are processed in your browser and are not uploaded to SuperTextHub. The tool is free, does not require an account, and supports transcript copy or download workflows.
Troubleshooting
The MP3 will not load
Re-export the file as a standard MP3, WAV, or M4A. Some unusual encoders can create files that browsers fail to decode.
The transcript misses words
Try a higher-quality MP3 or a WAV export if you have the original recording. Compression artifacts can hurt speech recognition.
The file is too large
Split long recordings into shorter segments and transcribe them one at a time.
Frequently Asked Questions
How large can my MP3 be?
Files up to 100MB are supported. Shorter files generally transcribe faster and use less browser memory.
Is the MP3 stored anywhere?
No. SuperTextHub does not receive or store your MP3 file.
Why is the first MP3 transcription slower?
The AI speech model downloads once, then your browser can reuse the cached model on later transcriptions.
