AMR (Adaptive Multi-Rate) is the standard codec for voice calls and voice notes on mobile phones. WhatsApp voice messages, recorded phone calls, and mobile voice apps all commonly produce AMR or AMR-WB files. ForgeFile is optimized to handle AMR's compressed, narrow-band audio and deliver accurate transcripts despite the lower audio quality compared to MP3 or WAV.

Upload your .amr or .awb file and receive a formatted transcript with speaker separation and timestamps. No conversion needed - the AMR file works directly. Exports available as TXT, DOCX, SRT, and VTT.

Frequently Asked Questions - AMR Voice Note Transcription

What formats are supported?

We support AMR (narrow-band) and AMR-WB (wideband, .awb extension) - both commonly produced by mobile phones, WhatsApp, and VoIP applications.

How accurate is AMR transcription?

AMR uses a narrow-band codec (typically 8 kHz) which limits audio quality compared to MP3 or WAV. Our AI is optimized for this compression and typically achieves 85–95% accuracy on clear AMR speech. Heavy background noise or very compressed files may reduce accuracy.

Can I transcribe WhatsApp voice notes in AMR format?

Yes. WhatsApp voice notes are typically saved as .opus (Android) or .m4a (iOS), but some older versions or exports produce .amr files. AMR files from WhatsApp exports can be uploaded directly.

Can you separate different speakers?

Yes. Speaker diarization labels each unique speaker in the transcript. Works well for two-party calls and smaller multi-person groups.

What output formats are available?

TXT (plain text), DOCX (editable Word document), SRT (subtitle file with timestamps), and VTT (WebVTT subtitle file).

Is my recording kept private?

Yes. All AMR files are uploaded over an encrypted connection, processed in an isolated environment, and permanently deleted after you download the transcript.
