Supported audio formats
All common audio formats are accepted. Video files (MP4, MOV, AVI, MKV, WEBM) work too.
.mp3
The most common audio format. Recordings from smartphones, podcasts, and voice recorders all export as MP3 by default.
.wav
Lossless audio favored by recording studios and researchers. Larger file size, no compression artifacts — ideal for high-accuracy transcription.
.m4a
The default format from iPhone Voice Memos and many Mac audio apps. Smaller than WAV while keeping good audio quality.
.flac
Free Lossless Audio Codec. Common in archival recordings and professional audio workflows.
.ogg
Open-source format used by browser-recorded audio and some Linux applications. Fully supported.
.opus
Modern codec used for voice calls (WhatsApp, Telegram audio messages). Can be transcribed directly without converting.
What people transcribe
Audio transcription isn't one thing — here's how different people use it.
Interviews
Journalists and researchers record interviews and need a written transcript to quote from. Uploading the audio file saves hours of typing.
Voice memos
Quick ideas recorded on the go. Transcribing them turns a scattered audio library into searchable notes.
Phone recordings
Customer calls, intake calls, recorded conversations. A transcript makes it easy to extract action items and share with a team.
Podcast episodes
Show notes, blog posts, and SEO content all start with a transcript. Upload the episode audio and edit from there.
Voice notes
Long WhatsApp or Telegram voice messages. Convert audio messages to text so you can read them at a glance.
Lectures and meetings
Recorded Zoom calls, university lectures, webinars. A transcript is easier to skim and reference than rewatching the recording.
AI transcription vs. typing it yourself
Manual transcription takes 4–6 hours of focused work per hour of audio — professional transcriptionists typically average 4× real time, and that's without corrections. AI transcription with TranscribTxt takes 3–5 minutes for the same hour of audio, with a 2.2% word error rate on clear recordings.
The practical difference: a 45-minute interview that would take most people 3+ hours to type becomes a file you upload before lunch and read before dinner. You still need to proofread for proper nouns and technical terms, but the bulk of the work is done.
Frequently asked questions
What audio formats are supported?
TranscribTxt accepts MP3, WAV, M4A, FLAC, OGG, and OPUS audio files, as well as video formats including MP4, MOV, AVI, MKV, and WEBM. Maximum file size is 2 GB.
Is my audio file kept private?
Your file is deleted from our servers immediately after transcription completes. We do not store recordings, share them with third parties, or use them for model training.
How accurate is audio transcription?
TranscribTxt uses ElevenLabs Scribe v2, which achieves a 2.2% word error rate on clean recordings — that's competitive with professional human transcription. Accuracy drops slightly on heavy background noise or strong accents, but performance on standard interviews, voice memos, and podcasts is very high.
Can I transcribe audio in languages other than English?
Yes. TranscribTxt supports 99 languages including Spanish, French, German, Portuguese, Russian, Japanese, Chinese, Arabic, Hindi, and many more. Language detection is automatic — you don't need to specify it before uploading.
