5 Tips for Better MP3 to Text Accuracy
1. Use High-Quality Audio
Clear audio is essential. Record with a good microphone in a quiet room. Avoid wind noise, echo, and background music. 128 kbps or higher MP3 quality is recommended.
2. Clean Up Audio First
Use free tools like Audacity to remove background noise and normalize volume before transcribing. This can improve accuracy by 10-15%.
3. Choose the Right Language
Always select the correct language before starting. If your MP3 contains multiple languages, transcribe each section separately for best results.
4. Split Long Files
For MP3s longer than 2 hours, split into smaller chunks. This makes editing easier and reduces processing errors. VoiceToTextOnline Pro supports files up to 500MB.
5. Always Proofread
Even 95% accuracy means 1 mistake every 20 words. Budget 10-15 minutes per hour of audio for proofreading and corrections.
