Which audio and video file formats are supported by this converter?

Checkistan Audio to Text Converter supports all common audio and video container formats including MP3, WAV, M4A (AAC/ALAC), OGG (Vorbis/Opus), FLAC, AAC, WEBM, WMA, AIFF, and MP4 video audio tracks without requiring any third-party codecs or software installation.

How does Checkistan guarantee 100% privacy for confidential audio recordings?

Unlike traditional cloud converters that upload your sensitive voice recordings, legal depositions, patient notes, or proprietary business meetings to external servers, Checkistan runs transcription algorithms directly in your browser memory and client sandbox. Your audio data never touches or stays on any remote server.

Can I download subtitles in SRT and WebVTT formats for YouTube and video editing?

Yes! Our converter automatically generates precise timecodes down to the millisecond. You can export subtitles directly as standard SubRip (.srt) files for YouTube, Premiere Pro, DaVinci Resolve, and Final Cut, or WebVTT (.vtt) files for modern web video players.

How accurate is the transcription for non-English languages like Urdu, Hindi, French, and Spanish?

Our multi-lingual speech engine is tuned for phonetic accuracy across over 100 global languages and dialects. It correctly handles complex scripts (such as Urdu Nastaliq and Hindi Devanagari), accents, regional idioms, and grammatical punctuation.

What is Speaker Diarization and how does it work?

Speaker Diarization identifies and separates distinct voices in a conversation (e.g., Speaker 1 vs Speaker 2). Our converter segments dialogues chronologically, assigns speaker tags, and lets you rename speakers (e.g., Interviewer, Host, Guest) before exporting.

Is there a limit on audio file length or daily conversions?

No! There are zero file length limits, no artificial paywalls, and no daily usage quotas. You can transcribe lectures, podcasts, interviews, and voice memos as often as you need completely free forever.

Can I edit the transcript and listen back to specific timestamps?

Yes. The built-in interactive audio player allows you to adjust playback speed from 0.5x to 2.0x, scrub with live waveform visualizers, and click any timestamp in the segment list to instantly jump audio playback to that exact second.

Which 7+ export formats are available for download?

You can download your transcript in 9 distinct formats: Plain Text (.txt), Microsoft Word (.docx), Formatted Vector PDF (.pdf), SubRip Subtitle (.srt), WebVTT (.vtt), Structured Data (.json), Spreadsheet Table (.csv), Markdown (.md), and Standalone Web Page (.html).
