Frequently asked questions
Is this audio to text converter really free?
Yes. You can transcribe up to 3 files per day with no signup. A free Atomiser account (no card required) unlocks full transcripts and 30 monthly credits for longer files, captions, clips and more.
What audio formats are supported?
MP3, WAV, M4A, AAC, OGG and FLAC. If you have a video file, use our free MP4 to MP3 converter first, or upload the video directly inside Atomiser.
How accurate is the AI transcription?
We use state-of-the-art speech recognition with word-level confidence scores. Clear single-speaker audio typically transcribes with very high accuracy; accuracy decreases with heavy crosstalk or background noise.
Which languages are supported?
The transcriber auto-detects the spoken language and supports 20+ languages including English, Hindi, Spanish, Portuguese, French and German.
Can I export subtitles from my transcript?
Yes — with a free Atomiser account you can export SRT/VTT subtitle files, burn animated captions into videos in 50+ styles, and even auto-generate clips from the same upload.
