AMR (Adaptive Multi-Rate Audio) AMR (Adaptive Multi-Rate Audio) is a speech-focused codec used in mobile phone networks worldwide. It encodes voice calls and voice messages on GSM and 3G networks. Because of AMR's acceptable for speech quality, Blazescribe delivers reliable results, especially when the original recording has clear speech.

Blazescribe supports AMR files up to 1 GB. AMR files are typically extremely compact — about 0.1 MB per minute (optimized for voice). Because of their compact size, most AMR files upload in seconds.

AMR is commonly used for phone call recordings, mobile voicemail, GSM/3G voice, WhatsApp (older versions). Transcribing these recordings lets you search through hours of content by keyword, create written summaries, generate subtitles, or repurpose the content for blogs and social media.

AMR files are narrowband (8 kHz sample rate) so they lack high-frequency detail. Blazescribe's models are trained on telephony-grade audio and handle AMR well despite the low bitrate. Additionally, clear speech with minimal background noise always produces the best results, regardless of file format.

Yes. After Blazescribe transcribes your AMR file, you can export the transcript as SRT or VTT subtitle files with accurate timestamps. These files can be paired with any video that uses the same audio.
