Frequently Asked Questions
What is the maximum MP3 file size? expand_more
The practical limit depends on the current upload allowance shown in the tool and your browser resources. For very long recordings, splitting the MP3 into smaller sections can speed up processing and make review easier.
How can I improve MP3 transcription quality? expand_more
Use the cleanest source file you have, reduce background noise, keep speakers close to the microphone, and avoid heavy music under speech. Clear recordings consistently produce better transcripts.
Which MP3 bitrates are supported? expand_more
Common MP3 bitrates such as 64 kbps, 128 kbps, 192 kbps, 256 kbps, and 320 kbps all work. Higher bitrate audio usually preserves speech detail better, which can help accuracy.
